Description

{Real Estate Buyer Selection System}

The present invention relates to a method for selling real estate at an appropriate price and at a desired time, and more specifically, to a method of determining a seller and an appropriate selling price, publicizing a property for sale at an amount obtained by multiplying the selling price by a flexible set rate, allowing flexible buyers to bid with small amounts, and selecting one successful buyer among them for the transaction, and when extracting a successful bid number, extracting the successful bid number through a public live broadcast at a specific time using a 64 to 256 BIT algorithm or a random method such as an arrow shooter, thereby providing higher reliability than existing speculative methods, so that a seller can dispose of his or her real estate at an appropriate price within a desired selling period, and a buyer is given the opportunity to select an expensive real estate that suits his or her taste and region and acquire it at a low price.

In general, in real estate transactions, the seller's real estate price at the time of sale is determined by market conditions or negotiations with brokers or buyers, but it was difficult to even determine the timing of the sale, which made it difficult. In addition, with the current real estate bubble bursting, the real estate market is shrinking, and as a result, even if they want to sell their real estate, they cannot sell it at an appropriate price and at a reasonable timing, turning them into a new type of house poor, and this could have a dangerous impact on the national economy.

In addition, due to inflation and interest rate instability, jeonse prices have skyrocketed and government-provided rental housing is still too expensive for ordinary citizens to purchase, forcing them to wander around in search of cheap jeonse (monthly rent).

In addition, many construction companies that have taken out PF loans and made investments are also facing the risk of bankruptcy due to the increase in unsold apartments, which has led to financial pressure and a worsening financial structure.

In addition, the controversy over manipulation of the gambling industry is constantly being raised, and public distrust continues to grow. The royalties that must be paid while using the lottery system and the spread of illegal gambling activities cannot but be serious problems for our economy.

The present invention has been devised to improve the above problems, and the purpose of the present invention is to prevent sellers from becoming house poor by selling their real estate at a desired time, to provide buyers who are wandering around without being able to find their own place with an opportunity to purchase real estate in an area of their choice at a low price, and to also provide construction companies facing bankruptcy to escape financial pressure by disposing of unsold apartments.

Another object of the present invention is to provide a real estate transaction system that provides an innovative real estate transaction method to all who are in conflict due to real estate, by extracting a successful bid number by a random method such as a 64 to 256 BIT algorithm method or an arrow shooting method through a public live broadcast at a specific time in order to select a fair and clear successful bidder, thereby providing higher reliability than existing gambling methods, and having a substitute function for illegal gambling and solving the above-described real-world problems, etc.

An operation method of a real estate transaction system according to one embodiment of the present invention is characterized by comprising the steps of: setting a transaction method of a real estate to be registered for sale for real estate sale; setting a bidding cost and a number of bidders for the real estate sale according to the set transaction method; receiving a bidding cost from a plurality of bidders for the real estate and receiving bidding information related to the transaction of the real estate; analyzing a first information group including at least one of the bidding information, the bidding cost, and the number of bidders according to the transaction method of the real estate to determine whether the transaction of the real estate is concluded; and selecting a successful bidder from the plurality of bidders if the transaction of the real estate is concluded according to the determination result, and performing a transaction processing for the selected successful bidder and a refund procedure for a certain percentage of non-successful bidders.

Meanwhile, in a real estate transaction system according to an embodiment of the present invention, the real estate transaction system comprises an electronic transaction server, and the electronic transaction server comprises a transaction method setting unit that sets a transaction method of a real estate to be registered for sale for real estate sale, a bid registration management unit that receives a bidding cost from a plurality of bidders for the real estate, receives bidding information related to the transaction of the real estate, and performs bidding registration processing, a transaction success determination unit that analyzes a first information group including at least one of the bidding information, the bidding cost, and the number of bidders according to the transaction method of the real estate to determine whether the transaction of the real estate is successful, and a transaction/refund processing unit that performs a transaction processing for a successful bidder selected from among the plurality of bidders when the transaction of the real estate is successful and a refund procedure of a certain percentage for non-successful bidders, and is characterized in that the bidding cost and the number of bidders for the real estate transaction are adjusted according to the transaction method set for the real estate.

According to another embodiment of the present invention, a real estate buyer selection system includes a seller terminal which accesses an online service for real estate transactions, registers a real estate to be sold, and provides information on the sale price and sale period of the registered real estate, a buyer terminal which accesses the online service, purchases virtual currency, and participates in a bid for the purchase of the registered real estate using the purchased virtual currency, and a real estate buyer selection device which provides a service screen of the online service, calculates a bid price of a preset amount and a number of possible bidders for the sale price of the real estate, and when the real estate is sold to a random user among the number of possible bidders by satisfying the number of possible bidders calculated above within the sale period, distributes a remaining bid amount obtained by subtracting the sale price from the total bid amount of the possible bidders to the users who did not win the bid.

The above real estate purchaser selection device can return a portion of the above bid price by dividing the remaining bid amount by the number of users who did not win the bid and distributing it equally.

The above real estate buyer selection device may request modification of information on the registered real estate property through the seller terminal when the number of possible bidders is not met within the above sales period.

The above real estate buyer selection device can communicate with the seller terminal and buyer terminal related to the successful bid real estate property, respectively, and proceed with the contract procedure using an artificial intelligence (AI) chatbot service.

The above real estate purchaser selection device is linked through API with the registration office server that processes the registration of the above registered real estate and the tax office server that processes tax payment work, and can provide a one-stop service that processes real estate transactions in one place through the artificial intelligence chatbot service and the API linkage.

The above real estate buyer selection device, when the above-mentioned successful bid is made, can create a messenger-based group room for the seller of the above-mentioned real estate, the buyer for whom the above-mentioned successful bid was made, and the broker who brokered the above-mentioned real estate, and then invite the seller, the buyer, and the broker to the created group room to proceed with the above-mentioned contract procedure in a chat manner.

The real estate transaction system of the present invention has the advantage of providing sellers and construction companies who are in a crisis due to failure to sell in a real estate market depressed by economic instability with the ability to dispose of real estate at a reasonable price within the period in which they wish to sell or distribute it, as well as the opportunity to purchase real estate that is still expensive despite the controversy over the real estate bubble at an extremely low price.

In addition, in order to select a fair and clear successful bidder, the winning number is extracted randomly using a 64 to 256 BIT algorithm or an arrow shooting method through a live broadcast at a specific time, providing higher reliability than existing gambling methods, and has various advantages such as being able to solve both the alternative function of illegal gambling and the real-world problems described above, providing an innovative real estate transaction system to everyone who is in conflict due to real estate.

Hereinafter, the present invention will be described in detail by describing preferred embodiments of the present invention with reference to the attached drawings. The same reference numerals presented in each drawing represent the same components.

FIG. 1 is a diagram showing the overall configuration of a real estate lottery sale method according to an embodiment of the present invention. As illustrated in FIG. 1, a real estate lottery sale method according to an embodiment of the present invention comprises: a set rate calculation server (100) that searches for sale information while executing a sale request contract with a seller, multiplies the agreed sale price by a flexible set rate to calculate a small amount and a flexible bidder number, and transmits the same to an electronic transaction server; a seller terminal (200) that negotiates the sale period and sale price of a real estate to be sold, writes a real estate sale contract in a separately provided form (exclusive transaction contract, etc.), and provides various sale documents (registration right certificate, seal certificate), etc., necessary for performing a real estate lottery sale; An electronic transaction server (400) that receives the arithmetic-processed listing information from the above-mentioned ratio arithmetic server, announces the listing information, processes the qualification requirements and cost processing of the purchasing members bidding thereon, generates and sends a bid number to the purchasing members who meet the conditions, receives a winning number from a winning number extraction server (500) when the number of bidders for the arithmetic-processed listing information is sufficient, generates a winning bid result matching the bid number, announces the winning bid result and sends it to the purchasing successful bidder, and stores the winning bid information; A buyer terminal (300) that searches for the arithmetic-processed listing from the above-mentioned electronic transaction server, conducts bidding on listings that match one's taste, and if the number of bidders for the arithmetic-processed listing is limited, conducts bidding on a first-come, first-served basis, undergoes an adult verification procedure for the qualification requirements of the purchasing members, and requests a bid number after going through a public authentication procedure for processing the bidding cost, and allows one opportunity for one listing; It is configured to include a winning number extraction server (500) that receives the arithmetic-processed listing information from the above-mentioned setup ratio arithmetic server, generates a specific time, extracts a winning number through a 64 to 256 BIT algorithm or a random method such as an arrow shooting through a public live broadcast to ensure a fair and clear drawing, and sends it to an electronic transaction server.

As mentioned above, each server can be operated independently, but if necessary, the setup ratio calculation server (100); the winning bid number extraction server (500); can be modularized and installed in the electronic transaction server (400).

The above seller terminal and buyer terminal refer to an unspecified number of persons, and the type of terminal is not limited to a computer terminal, mobile terminal, etc., as long as it can access a website and does not interfere with using the system of the present invention.

FIG. 2 is a block diagram of a setting ratio calculation server (100) for a real estate lottery sale method according to one embodiment of the present invention.

As illustrated in FIG. 2, the setup ratio calculation server (100) according to an embodiment of the present invention includes: a sales contract writing unit (110) that receives a certain rate of commission from the selling price by referencing real estate information set by the seller terminal (200) and writes information on the selling price and the selling period; a sales information search unit (120) that analyzes and searches the actual transaction price and rights of the real estate in question by referencing the information of the sales contract writing unit (110); a setup ratio calculation unit (130) that multiplies the selling price agreed upon based on the sales contract writing unit (110) by a flexible setup ratio to calculate the purchase bid amount and the number of purchase bidders; a listing information generation unit (140) that generates listing information by referencing the bid amount and number calculated by the setup ratio calculation unit (130) and the listing information analyzed by the selling information search unit (120); It is configured to include an item information transmission unit (150) that transmits the item information generated from the above item information generation unit (140) to an electronic transaction server (400).

In particular, the setup ratio arithmetic unit (130) is characterized by multiplying the selling price agreed upon with the selling member by a flexible setup ratio to calculate the purchase bid amount and number of people.

For example, if the agreed selling price is 300 million won and the flexible setting ratio is 0.003% of the selling price and the number of bidders is set to 15 times the selling price, then the bidding price will be 10,000 won and the number of bidders will be 45,000, so 45,000 people can bid on a first-come, first-served basis during the selling period. To explain in more detail, the selling price varies depending on the use of the real estate such as apartments, houses, land, and commercial properties, the bidding price setting ratio is a flexible number that is applied by multiplying the selling price by 000000001 to 1 to make a small bidding price, and the number of bidders is a flexible number that is applied by multiplying the number of bidders by 1 to an infinite number, so that the bidding price and number of bidders differ for each property.

FIG. 3 is a block diagram showing an electronic transaction server (400) for a real estate lottery transaction method according to one embodiment of the present invention.

As illustrated in FIG. 3, an electronic transaction server (400) according to an embodiment of the present invention comprises: an item information request storage unit (405) that receives and stores item information generated by arithmetic processing from a setup ratio calculation server (100); an item information announcement unit (410) that announces the item information stored by the item information request storage unit (405) on a website; a bid qualification authentication unit (415) that authenticates the adult authentication and real name qualifications of members who wish to bid after viewing the item information announced through the item information announcement unit (410); a bid cost settlement unit (420) that settles the arithmetic-processed purchase bid amount of members who have passed the bid qualification authentication unit (415); When a cost processing completion signal is received by the above-mentioned bid cost settlement unit (420), a bid number generation and transmission unit (425) which generates a unique bid number and transmits it to the buyer terminal (300); a setting ratio control unit (430) which determines whether the purchase bid amount and number of bidders calculated by the setting ratio calculation server (100) have been met or not, and if so, transmits the condition to the bid number request storage unit (440), and if not, to the escrow management unit (435); an escrow management unit (435) which returns the amount of the purchasing bidder when the condition is not met from the setting ratio control unit (430); a winning number request storage unit (440) which requests a winning bid number from the setting ratio control unit (430) when the condition is met and receives and stores it; It is composed of a winning result generation unit (445) that extracts matching information from among the winning number stored by the winning number request storage unit (440) and the information of the winning number generated by the winning number generation and transmission unit (425); a winning result transmission announcement unit (450) that transmits the information extracted by the winning result generation unit (445) to the buyer terminal (300) and announces it on the website; and a winning information storage unit (455) that stores the overall information generated by the winning result generation unit (445), member information, result information, etc., as evidence of the terms and conditions set by this system.

In particular, the setting ratio control unit (430) has the characteristic of controlling the satisfaction of conditions for the purchase bid amount and number of people calculated from the setting ratio calculation server (100) and ensuring a fair and clear real estate lottery sale method.

FIG. 4 is a block diagram showing a winning bid number extraction server (500) of a real estate lottery sale method according to one embodiment of the present invention.

As illustrated in FIG. 4, a winning number extraction server (500) according to an embodiment of the present invention comprises: a specific time information generation unit (510) for generating specific time information for extracting a winning number; a 64 to 256 BIT algorithm operation unit (520) for randomizing the information to extract a fair winning number at the specific time generated by the specific time information generation unit (510); a winning number extraction unit (530) for extracting a winning number in a random manner, such as by shooting an arrow, to extract a fair winning number at the specific time generated by the specific time information generation unit (510); a winning number reception storage unit (540) for receiving and storing the winning numbers extracted by the 64 to 256 BIT algorithm operation unit (520) and the winning number extraction unit (530); It is configured to include a winning number transmission unit (550) that transmits the winning number generated in the winning number reception storage unit (540) to the electronic transaction server (400).

In particular, the method for extracting the winning bid number described in the present invention may be a 64 to 256 [0058] BIT algorithm operation unit (520) that is a random number processing method, or may be a random method such as an arrow shooting method. Any random method that can execute a public live broadcast at a specific time and extract a fair winning bid number within that time will be acceptable for operating the system of the present invention.

Fig. 5 is a flow chart showing a real estate transaction method according to one embodiment of the present invention. The various operations illustrated in Fig. 5 may be performed through the electronic transaction server, the set ratio arithmetic server, and the winning bid number extraction server illustrated in Fig. 1, or may be performed by the electronic transaction server, the set ratio arithmetic server, and the winning bid number extraction server according to another embodiment of the present invention to be described below.

As illustrated in Figure 5, a property is registered for a real estate sale transaction (S11). For the registration of a property, the agreed sale period and sale price, the written real estate sale contract, and various sale documents can be registered on the electronic transaction server.

For the sale transaction of the above registered property, a property transaction method is set (S12). According to an embodiment of the present invention, real estate properties can be sold according to various transaction methods, and real estate transactions are made according to different transaction methods for each real estate property, thereby allowing sales to be made according to the optimal transaction method for each real estate.

In addition, according to an embodiment of the present invention, the transaction method may include two or more methods, a lottery transaction method and an auction transaction method, and further, the auction transaction method may include a first auction transaction method that places a limit on the number of people and a second auction transaction method that does not place a limit on the number of people.

As above, when the property is registered and the property transaction method is set, the bidding process is carried out by the bidders providing the prescribed bidding fee or commission and bidding information. The bidding information may include information related to the bidder or information related to the auction price when the auction transaction method is in progress.

First, it is determined whether the transaction for a given real estate is conducted by a lottery transaction method (S13). As a result of the determination, if the real estate is traded by a lottery transaction method, the bidding cost and the number of people are set (S14). The setting of the bidding cost and the number of people can be performed in the setting ratio calculation server as described above, and the bidding cost can be calculated by multiplying the selling price of the real estate by the flexible setting ratio. In addition, the number of people can be set by considering the flexible setting ratio, and for example, if the total bidding cost is set to be 15 times the selling price of the real estate, the number of people can be set to 45,000 when the selling price is 300 million and the bidding price is 10,000 won.

On the other hand, if the transaction for real estate is not conducted by the lottery method, it is determined whether the real estate is traded according to the first auction method (S15). If the determination result shows that the real estate is traded by the first auction method, a step of setting the commission and the number of bidders is performed (S16_1). In the case of a transaction according to the auction method, rather than adding up the bidding cost and trading the real estate through a lottery among the bidders, the transaction can be conducted by a method in which the bidder who offers the highest bid price among the bidders is successful.

According to an embodiment of the present invention, the first auction method is a method for conducting an auction with a limited number of bidders, and for this purpose, when a transaction is conducted by the auction method (e.g., the first auction method), the fee (bidding cost) to be paid by the bidder and the number of bidders are set. That is, the bidding cost and the number of bidders may be set differently depending on the type and sale price of each real estate, and the bidding cost may be calculated by multiplying the sale price by a flexible setting rate, and further, the limited number of bidders may be set in consideration of the flexible setting rate. For example, when the sale price of real estate is 100 million won, the bidding cost may be set to 10,000 won by multiplying the flexible setting rate, and further, the number of bidders may be set to 10,000 in consideration of the bidding cost and the sale price of real estate.

Meanwhile, if the above judgment result shows that the real estate is not traded according to the first auction method, the real estate is determined to be traded according to the second auction method. According to an embodiment of the present invention, the second auction method is a method for conducting an auction without limiting the number of bidders, and for this purpose, a fee (bidding cost) to be paid by a bidder is set when a transaction is conducted according to the auction method (e.g., the second auction method). The bidding cost and the number of bidders may also be set differently depending on the type and sale price of each real estate, and the bidding cost may be calculated by multiplying the sale price by a flexible setting rate. For example, if the sale price of the real estate is 100 million won, the bidding cost may be set to 10,000 won by multiplying the flexible setting rate. The fee is set according to the calculated bidding cost (S16_2).

According to the above real estate transaction method, when various information required for bidding is set, various bidding information is received from bidders who wish to purchase real estate (S17). Authentication processing is performed using information such as adult authentication and real name of members who wish to bid through the announced property information, and cost processing required for bidding is also performed. When bidding processing is normally completed, a bidding number is generated and sent to the bidder (S19).

The above bidding process is performed for multiple bidders, and then it is determined whether the bidding period has elapsed, or if the number of bidders is limited by the lottery transaction method or the first auction transaction method, it is determined whether the number of bidders has elapsed (S19). As a result of the above determination, if the bidding period or the number of bidders has not elapsed, the steps of continuously receiving and processing bidding information from bidders and sending a bidding number are performed, and if the bidding period or the number of bidders has elapsed, the bidding procedure for the real estate transaction is terminated (S20).

The method of real estate transaction according to the embodiment of the present invention described above is a process of performing bidding processing from multiple bidders starting from registering a property for sale, and the transaction can be performed in various forms depending on the characteristics of each real estate, for example, whether each real estate is appropriately traded by auction or by lottery. In addition, in relation to real estate transactions with many failed bids due to low interest from buyers, real estate transactions can be activated by inducing purchases of real estate through simple bidding, and the stability of the transaction can be improved.

In addition, in the above embodiment, the cost paid by bidders in the lottery method is defined as a bidding cost, and the cost paid by bidders in the first and second auction methods is defined as a commission. However, the basic cost for participating in a bidding may also be defined as a bidding cost.

Fig. 6 is a flow chart showing a method of real estate transaction according to another embodiment of the present invention. In the case of the embodiment of Fig. 6, an example of the operation process from the end of the bidding stage to selecting a successful bidder and performing the transaction procedure is shown.

The e-commerce server performs real estate transaction procedures using a large amount of bidding information received and registered through the bidding process.

First, a step is performed to analyze the bidding information and determine the transaction method for the real estate in question (S21). As described above, the transaction method according to the embodiment of the present invention may include a lottery transaction method, a limited-person auction method (hereinafter, the first auction method), and an unlimited-person auction method (hereinafter, the second auction method).

First, it is determined whether the transaction method for the above real estate is a lottery transaction or a first auction method (S22). That is, based on the result of the above determination, it is determined whether the transaction method for the above real estate is a lottery transaction or a first auction method with a limited number of bidders, or a second auction method with an unlimited number of bidders.

As a result of the above judgment, if the transaction method for the relevant real estate is a lottery transaction or a first auction method, the number of bidders who have bid for the relevant real estate is determined (S23). This can be determined by analyzing the bidding information stored in a database within the electronic transaction server. On the other hand, if the transaction method for the relevant real estate is a second auction method, the auction price and commission information are extracted from the bidding information received through the bidding process, and a process of calculating the auction price and commission with each other is performed (S24).

In the case of the lottery transaction or the first auction method, when the number of bidders is determined, it is determined whether the number of bidders is greater than or equal to a predetermined set value (S25). That is, in the case of the lottery transaction or the first auction method, whether the transaction is successful can be determined based on the result of comparing the number of bidders with the predetermined set value when determining whether the transaction is successful. If the number of bidders is greater than or equal to the predetermined set value, the transaction is determined to be successful, and the process of selecting a successful bidder is then performed (S28).

The above-mentioned successful bidder selection process can extract a successful bid number randomly or by using a BIT algorithm to extract a fair successful bid number at a specific time as described above.

Meanwhile, if the number of bidders is less than the set value, the sale transaction is judged not to have been successful, and the sale is canceled and the bid fee paid by the bidder is refunded (S27). In other words, the real estate subject to the sale transaction can be registered again as a sale item in the future and the sale price or sale transaction method can be adjusted to attempt the sale.

Meanwhile, if the transaction method for the real estate in question corresponds to the second auction method, an operation is performed to compare the result (operation value) of calculating the auction price and commission with a predetermined amount (S26). As an example, an operation may be performed to add the highest auction price among the auction prices received from multiple bidders and the sum of the commissions from all bidders, and an operation may be performed to determine whether the calculated value is higher than the sale price of the real estate in question. However, the embodiment of the present invention is not limited thereto, and it may also be determined whether the calculated value is higher than a value obtained by adding a certain amount to the sale price of the real estate in question. The certain amount may be a type of closing fee provided to a transaction brokerage business (or system operator) when a sale transaction for the real estate in question is concluded, and may be set as, for example, an amount corresponding to a certain percentage (for example, 1%) of the real estate sale price.

In other words, if the sum of the highest bid and the commission from all bidders is greater than the sum of the real estate sale price and the above-mentioned closing fee, the sale transaction can be concluded.

On the other hand, if the above operation value is less than the selling price, the transaction may not be concluded. In this case, the transaction may be cancelled and the bidding fee deposited by the bidder may be refunded, as in step S27 described above.

Depending on the transaction method set for the relevant real estate, whether or not a sale transaction is successful is determined in different ways, and if the sale transaction is successful, after the successful bidder selection process, the real estate sale procedure with the successful bidder is performed, and a partial refund processing procedure is performed in which a portion of the bid amount is distributed to the bidders or a portion of the commission is distributed to the bidders (S29).

Meanwhile, as the aforementioned transaction methods, examples of real estate transaction methods according to the first auction method and the second auction method are explained using the following table.

Table 1 shows an example of a real estate transaction according to the first auction method. The selling price of the real estate is 100 million won, and the setting fee is set as a bid participation fee as a result of multiplying the selling price by a flexible setting rate (for example, one ten-thousandth to one hundred-thousandth). For example, the selling price of the real estate is 100 million won and the bid participation fee is set at 10,000 won. Considering this, the number of bidders is

This can be set to 10,000 people. In this case, if all 10,000 bidders pay the fee, the total amount of the bidding fee will be 100 million won, which is the same as the real estate sale price. Each bidder can participate in the auction process by paying the above fee, and for the actual real estate transaction, in addition to the fee, the information on the auction price (bidding price) that he/she proposes for bidding is provided to the electronic transaction server.

The starting price of an auction can start from a certain value, for example, as shown in Table 1, the starting price can be 1 million won, which is 1% of the selling price. The bidder who offers the highest bid among the bidders wins the auction, and the winning bidder can purchase the property by paying the bid price, income tax, and purchase cost in addition to the commission. In addition, the subsidy provided to the winning bidder can be the amount of the selling price minus the winning bid price.

In the first auction method as shown in Table 1, the number of bidders is limited to 10,000. Accordingly, the electronic transaction server determines the number of bidders, and if the number of bidders does not reach 10,000, the transaction is cancelled and a refund is processed. Meanwhile, the real estate seller is provided with the amount equivalent to the auction price from the successful bidder, and for the remaining amount, a portion of the commission from multiple bidders is provided, thereby providing the real estate sale price. In addition, for the remaining portion of the above commission, a certain percentage of the remaining commission other than the closing fee provided to the transaction intermediary (or system operator) can be refunded to multiple bidders.

Meanwhile, Table 2 is a table showing an example of a real estate transaction according to the second auction method, where the sale price of the real estate is 100 million won, and the sale price is multiplied by a flexible set rate (for example, one ten-thousandth to one hundred-thousandth), and the set fee is set as the bid participation fee. On the other hand, since there is no limit on the number of bidders, a greater number of bidders can participate in the real estate transaction, and accordingly, there is no limit on the total amount of the bid fee.

In the second auction method, whether or not a sale transaction is successful is determined by a different method. That is, if the number of bidders is small and the total amount of the auction price and commission is less than the real estate sale price, the sale transaction cannot be successful. In this case, the result of calculating the auction price and the total amount of commission is used to determine whether or not a sale transaction is successful. For example, if the sale price is greater than the sum of the highest bid price and the total amount of the bid commission, the sale transaction may be unsuccessful. Alternatively, if the sum of the highest bid price, the total amount of the bid commission, and a certain percentage (e.g., 3%) of the sale price is greater than the sale price, considering the success fee of the transaction intermediary (or system operator) as shown in Table 2, the sale transaction may be successful. If the sale transaction is successful, the real estate sale transaction may proceed through the assistance and expenditure of the successful bidder in the same way as in the first auction method described above.

Meanwhile, as in the above-described embodiment, in the case of the lottery method, the first and second auction methods in the present invention, the conditions for determining whether a transaction is successful may be set differently. Accordingly, among the plurality of pieces of information including the bidding information, bidding cost, and number of bidders, the information used in the lottery method may be defined as the first information group, and the information used in the first and second auction methods may be defined as the second and third information groups, respectively.

Fig. 7 is a flow chart showing a method of real estate transaction according to another embodiment of the present invention. In the embodiment of Fig. 7, an example is described in which, in a real estate transaction system according to an embodiment of the present invention, at least two transaction methods are automatically switched according to the bidding results.

As shown in Fig. 7, a step of analyzing the bidding information and determining the transaction method for the real estate is performed (S31). It is assumed that the bidding procedure for the real estate is conducted through an auction method, and first, it is determined whether the bidding procedure for the real estate is conducted through the first auction method (S32).

As a result of the above judgment, if the above real estate has undergone a bidding process through the first auction method, since the first auction method is a limited-person auction method, the number of bidders who have bid for the above real estate is determined. In addition, if the number of bidders is determined, it is determined whether the number of bidders is greater than a predetermined set value (S33). The predetermined set value may be a value set by considering various information such as the sale price of the real estate and the flexible set ratio value as in the above-described embodiment.

If the above real estate is not subject to a bidding procedure through the first auction method, it is determined that the above real estate is subject to a bidding procedure through the second auction method, and subsequent operations are performed. Alternatively, if the number of bidders is less than a predetermined set value in step S33, the auction method is switched to sell the above real estate through the second auction method. In the above case, in order to perform a real estate sale transaction according to the second auction method, an operation is performed to compare the result (calculated value) of calculating the auction price and commission with a predetermined amount (S34). If the calculated value is less than the selling price, the sale transaction may not be completed, and accordingly, an operation is performed to cancel the sale and process a refund (S35).

Meanwhile, as described above, if the number of bidders is greater than or equal to a predetermined value according to the first auction method, or if the calculated value is greater than or equal to the selling price according to the second auction method, the relevant sale transaction can be concluded. Accordingly, the first auction method or the second auction method is automatically switched, and the real estate sale transaction is performed according to one of the methods. To this end, after the successful bidder selection process (S36), the real estate sale procedure with the successful bidder is performed, and a partial refund processing procedure is performed in which a portion of the bid amount is distributed to the bidders or a portion of the commission is distributed to the bidders (S37).

By the real estate transaction method according to the embodiment of the present invention described above, a customer who wishes to sell real estate can sell real estate in various transaction forms based on the characteristics of his or her real estate, his or her intention to sell, etc., and a customer who wishes to purchase real estate can also attempt to purchase real estate through a small amount (by lottery) if necessary, or can attempt to purchase real estate through a normal auction method (first and second auction methods). In addition, by the real estate transaction method according to the embodiment of the present invention, a convenient and stable real estate transaction system is provided for sellers and buyers, thereby improving the convenience and stability of transactions and activating real estate transactions.

FIG. 8 is a block diagram showing an implementation example of an electronic transaction server of a real estate transaction system according to one embodiment of the present invention.

The system illustrated in FIG. 8 is an implementation example for performing the real estate transaction operation method of FIGS. 5 to 7 described above. Each of the configurations illustrated in FIG. 8 may have different terminology from the configurations of the various servers illustrated in FIGS. 2 to 4. However, each of the configurations illustrated in FIG. 8 may be a configuration included in the configurations of the various servers illustrated in FIGS. 2 to 4, or may be an equivalent (or identical) configuration thereto. Alternatively, each of the configurations of FIG. 8 may be a concept including at least one of the configurations of the various servers illustrated in FIGS. 2 to 4.

As illustrated in FIG. 8, the electronic transaction server (1000) of the real estate transaction system may include a system [0096] control unit (1100), a property registration management unit (1200), a transaction method setting unit (1300), a property information receiving unit (1400), and a bid registration management unit (1500).

In addition, the electronic transaction server (1000) may further include a transaction method management unit (1600), a transaction success determination unit (1700), a successful bidder selection unit (1800), and a transaction/refund processing unit (1900), and the electronic transaction server (1000) may further include a database unit (1910) that stores various types of information related to real estate sales transactions according to an embodiment of the present invention in a database.

The system control unit (1100) controls the overall operation of the electronic transaction server (1000) and can also control the operation of various components provided in the electronic transaction server (1000). The property registration management unit (1200) registers various information related to real estate to be traded, and can register, for example, the agreed sale period and sale price, the written real estate sale contract, and various sale documents.

The transaction method setting unit (1300) sets the transaction method for each real estate to be traded. According to an embodiment of the present invention, by allowing each real estate to be traded according to at least two transaction methods, the transaction is performed according to the optimal transaction method for each real estate. For example, the transaction method for a property may include a lottery transaction method and an auction transaction method as two or more methods, and further, the auction transaction method may include a first auction transaction method that places a limit on the number of participants and a second auction transaction method that does not place a limit on the number of participants.

The listing information receiving unit (1400) receives listing information, such as the bid cost and number of people set for the corresponding real estate. The listing information receiving unit (1400) may receive the listing information from a server (e.g., a setting ratio calculation server) located outside the electronic transaction server (1000) of the real estate transaction system of the present invention. Although not shown, the electronic transaction server (1000) may perform a setting operation, such as the bid cost and number of people for the corresponding real estate, and in this case, the configuration of the listing information receiving unit (1400) may be omitted.

Meanwhile, as each property is registered and the transaction method for the property is set, bidding processing is performed according to the set transaction method. The bidding registration management unit (1500) performs registration processing using bidding information such as a predetermined bidding fee, commission, and auction price provided by bidders. Authentication processing is performed using information such as adult authentication and real name of members who wish to bid through the announced property information, and also, when the cost processing operation required for bidding is performed and the bidding processing is completed normally, a bidding number is generated and sent to the bidder. In addition, for normal bidding processing, the bidding registration management unit (1500) can determine whether the bidding period for the property or the set number of bidders has been exceeded.

The electronic transaction server (1000) performs a successful bid processing operation for the real estate after the above-mentioned bidding processing operation is completed. The transaction method management unit (1600) can determine the transaction method set for the real estate for the successful bid procedure and output the determination result. The determination result is provided to another component within the electronic transaction server (1000) so that the successful bid processing is performed according to the transaction method set for the real estate.

In addition, the transaction method management unit (1600) can manage the transaction method for the real estate to be automatically switched based on the bidding processing result in order to flexibly perform the real estate sale transaction and reduce the probability of the failure of the bidding. For example, the transaction method management unit (1600) receives whether the transaction for the real estate has been concluded (whether the conditions for successful bidding have been met) and controls the switching of the transaction method for the real estate using this. If the transaction method for the real estate is currently set to the first auction method, whether the transaction has been concluded can be determined based on the result of first determining whether the number of bidders is greater than a predetermined set value, and if the transaction information is provided to the transaction method management unit (1600), the transaction method management unit (1600) switches the transaction method for the real estate to the second auction method. Accordingly, the result of calculating the highest auction price among the auction prices received during the bidding process for the real estate and the commission from the bidders is compared with the predetermined amount to determine whether the transaction for the real estate has been concluded. Depending on the results of the judgment, subsequent bidding processing procedures may be carried out.

The transaction success determination unit (1700) determines whether a transaction for the relevant real estate is successful by using the bidding results according to each transaction method as described above. As described above, if the real estate follows the lottery transaction method or the first auction method, the number of bidders who have bid for the relevant real estate is determined by using the bidding results, and whether a transaction is successful can be determined based on the result of comparing the number of bidders with the predetermined set value. On the other hand, if the transaction method for the relevant real estate corresponds to the second auction method, the auction price and commission information are extracted from the bidding information received through the bidding process, and the auction price and commission are calculated with each other, and then the result of the calculation is compared with the predetermined value, thereby determining whether a transaction is successful.

Meanwhile, the bidder selection unit (1800) selects the bidder by randomly extracting the winning number or by using the result of extracting the winning number using the BIT algorithm. As described above, if a predetermined winning number extraction server is placed outside the e-commerce server (1000), the winning number can be provided from the winning number extraction server to the e-commerce server (1000), and the bidder selection unit (1800) performs the winning bidder selection operation by using the received winning number. The transaction/refund processing unit (1900) processes the real estate transaction procedure with the winning bidder according to the winning bid result, and also performs a partial refund processing procedure of distributing a portion of the bid amount to the bidders or distributing a portion of the commission to the bidders.

Fig. 9 is a block diagram showing a detailed implementation example of the electronic transaction server of Fig. 8. For convenience of explanation, Fig. 9 shows an implementation example of a transaction method setting unit (1300), a bid registration management unit (1500), a transaction method management unit (1600), and a transaction success determination unit (1700).

The transaction method setting unit (1300) may include a lottery transaction setting unit (1310), a limited-person auction setting unit (1320), and an unlimited-person auction setting unit (1330). Each of the setting units sets a transaction method for each property using the listing information for the relevant property (e.g., information such as bid price, commission, and limited number of people), and sets information such as bid price, commission, and limited number of people according to the relevant transaction method.

In addition, the bid registration management unit (1500) may include a bid information receiving unit (1510), a bid number transmitting unit (1520), a bid registration processing unit (1530), and a bid period determining unit (1540). The bid information receiving unit (1510) receives bid information such as a predetermined bid fee or commission, and an auction price provided by bidders. In addition, after authentication processing is normally performed for each bidder, the bid number transmitting unit (1520) generates a bid number and transmits it to the bidder. The bid registration processing unit (1530) performs an operation of registering and processing various bid information from the bidder and the bid number transmitted to the bidder within the system. In addition, the bid period determining unit (1540) determines the bid period for the real estate transaction in question, and registers the bid normally or disallows registration depending on whether the period has been exceeded.

Meanwhile, the transaction method management unit (1600) may include a transaction method judgment unit (1610), a transaction information reception unit (1620), and a transaction method conversion unit (1630). The transaction method judgment unit (1610) refers to information related to various sales transactions stored in the database unit (1910) within the system to judge the transaction method set for the relevant real estate and outputs the judgment result. The judgment result may be used by various other components within the system.

The transaction information receiving unit (1620) receives information related to whether or not a transaction has been concluded from the transaction conclusion judgment unit (1700), and based on this, switches the transaction method set for the relevant real estate. The transaction method switching unit (1630) performs a switching operation, such as switching the transaction method of the relevant real estate from the lottery method to the auction method, or switching from the first auction method to the second auction method, using the transaction information from the transaction information receiving unit (1620). When such a switching operation is performed, the transaction method for the relevant real estate is automatically switched, and the sales procedure is performed according to the switched method.

Meanwhile, the transaction conclusion judgment unit (1700) may include a bid information analysis unit (1710), an auction price and commission calculation unit (1720), and a threshold value comparison unit (1730). The bid information analysis unit (1710) analyzes bid information to analyze information related to the transaction method set for the relevant real estate, or information such as the number of registered bidders, auction price, and commission.

The auction price and commission calculation unit (1720) performs a predetermined calculation process using the information such as the analyzed auction price and commission. That is, in order to determine whether a transaction according to the second auction method is successful, the auction price and commission information are extracted from the bidding information, and the process of calculating the auction price and commission with each other is performed. The threshold comparison unit (1730) performs a predetermined comparison operation to determine whether a transaction is successful using information related to the transaction method or information such as the number of registered bidders, the auction price, and commission. For example, it determines whether the number of bidders is equal to or greater than a predetermined set value according to the lottery method or the first auction method, and it can also determine whether the calculation result from the auction price and commission calculation unit (1720) is equal to or greater than the sale price of the corresponding real estate (or the sum of the sale price and a predetermined closing fee) according to the second auction method. The threshold value may correspond to the aforementioned predetermined set value or may be a value corresponding to the sale price of the corresponding real estate.

FIG. 10 is a block diagram showing an implementation example of a setup ratio arithmetic server of a real estate transaction system according to one embodiment of the present invention.

A real estate transaction system according to one embodiment of the present invention may further include a set ratio arithmetic server (2000) in addition to an electronic transaction server (1000), and the set ratio arithmetic server (2000) may further include a set ratio arithmetic unit (2200), a set ratio conversion unit (2300), and a listing information generation/transmission unit (2400) together with a system control unit (2100) that controls the operation of the entire system.

The set ratio calculation unit (2200) performs an operation of calculating the purchase bid amount and the number of purchase bidders by multiplying the sale price of the real estate that has been agreed upon by the agreement by the flexible set ratio, and provides the result of the calculation to the electronic transaction server (1000). The set ratio conversion unit (2300) performs an operation of converting the set ratio in order to adjust the bid amount (or commission) or the number of bidders according to the real estate sale transaction method, and provides information related to the converted set ratio to the set ratio calculation unit (2200). The listing information generation/transmission unit (2400) generates listing information including information related to the calculated bid amount and the number of bidders, and transmits the listing information to the electronic transaction server (1000) by referring to the listing information analyzed by the above-mentioned selling information search unit (120).

Although the present invention has been described with reference to the embodiments shown in the drawings, these are merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Accordingly, the true technical protection scope of the present invention should be determined by the technical idea of the appended claims.

FIG. 11 is a drawing showing a real estate buyer selection system according to another embodiment of the present invention, and FIG. 12 is a drawing schematically showing the real estate buyer selection process of FIG. 11.

As illustrated in FIG. 11, a real estate buyer selection system (or real estate transaction system) (3090) according to an embodiment of the present invention includes part or all of a seller terminal (4000), a buyer terminal (4010), a communication network (4020), a real estate buyer selection device (or real estate transaction service device) (4030), and a third-party device (4040).

Here, the term "including some or all" means that some components, such as a communication network (4020) or a third-party device (404), are omitted so that the system (3090) is configured so that, for example, the seller terminal (4000) or the buyer terminal (4010) performs direct communication (e.g., P2P, etc.) with the real estate buyer selection device (4030), or some or all of the components constituting the real estate buyer selection device (4030) can be integrated into a network device (e.g., a wireless switching device, etc.) constituting the communication network (4020), and is explained as including all in order to help a sufficient understanding of the invention.

The seller terminal (4000) refers to a user device of a user who wants to sell his or her own real estate, and includes various devices such as a smart phone, a tablet PC, a laptop computer, a desktop computer, a smart TV, and even a wearable device that the user wears on his or her wrist. In addition, the seller terminal (4000) may include a device operated by a real estate agent or brokerage firm that delegates work to the owner selling the real estate and acts on his or her behalf.

The seller terminal (4000) can connect to a real estate transaction service, etc., provided by the real estate buyer selection device (4030) to sell real estate and proceed with the sale of real estate. As can be seen in Fig. 12, the seller terminal (4000) can connect to the service and register property information.

Through this, sellers can dispose of their real estate at a reasonable price within the period they wish to sell through the real estate transaction system, and buyers are given the opportunity to select expensive real estate to their taste and acquire it at a low price, and sellers decide on the appropriate selling price and period when registering a property for transaction. Of course, if the seller initially wanted to sell within the registered selling price and period, but the number of buyers participating in the bid, i.e. the number of bidders, is insufficient, additional actions can be taken to modify the already registered information.

In addition, the seller terminal (4000) can check the process of trading a property registered in the real estate transaction service (e.g., online website) provided by the real estate buyer selection device (4030) through a broadcast lottery method, or can be notified of the lottery result, and if the buyer is selected, can be notified of this from the real estate buyer selection device (4030). Of course, additional actions for concluding a contract with the buyer can be performed later. Such a contract can be performed by attaching contract documents through a service provided by the real estate buyer selection device (4030), etc. For example, in the case where an artificial intelligence chatbot service is used for concluding a contract, the chatbot service can be performed in a messenger manner, and the contracting parties can attach documents through the chatbot service and sign the contract, etc., so the embodiment of the present invention will not be particularly limited to such a contract method. Here, the AI chatbot service is a combination of AI technology and messenger-based chatbot technology, and can be seen as characterized by the AI robot for chatting recognizing the status of the seller and buyer and automatically operating to perform the appropriate next procedure. For example, if it is the buyer's turn to sign but there is no signature, a message requesting the buyer to sign can be sent to the buyer's terminal (4010) through the chatbot service.

The buyer terminal (4010) is a user terminal device of buyers who participate in the bidding by accessing the web service provided by the real estate buyer selection device (4030) to purchase real estate items registered by sellers who wish to sell real estate. Therefore, it may also be called a bidder. Of course, the buyer terminal (4010) may also include various devices such as a smartphone, tablet PC, or desktop computer, just like the seller terminal (4010). In addition, the buyer terminal (4010) may also include a user device such as a real estate transaction broker or agent who participates in the bidding according to a contract of authority with the buyer.

Of course, before that, the buyer terminal (4010) is registered as a member in order to use the web service according to the embodiment of the present invention, just like the seller terminal (4000), and in particular, the buyer, i.e. the user of the buyer terminal (4010), can purchase and use points or cyber money, etc. to use on the web service in order to participate in the bidding. In other words, the buyer of the buyer terminal (4010) can use his/her credit card, etc. that has been registered through points, cyber money, or even online money charging, etc. to participate in the bidding on the real estate buyer selection device (4030). In addition, it is possible to participate in the bidding on the service provided by the real estate buyer selection device (4030) using the purchased points or cyber money. Of course, it is possible to participate in the bidding by depositing a fixed amount of money required for participation in the bidding into the account of a company providing a web service without using points or virtual currency and receiving permission to participate in the bidding from the real estate buyer selection device (4030), so the embodiment of the present invention will not be particularly limited to any one form.

In addition, the buyer of the buyer terminal (4010) may receive a portion of the point amount paid to participate in the bid. For example, if 10,000 won is paid for the bid with points, the amount minus a certain amount of commission may be returned if the bid is not successful. Of course, the buyer terminal (4010) may be notified of this fact from the real estate buyer selection device (4030). In addition, the bid participation fee paid to participate in the bid varies depending on the selling price of the real estate to be sold, and therefore, the amount returned will naturally vary even if the bid is not successful, that is, if the bid is not successful. In addition, since the amount to be returned is distributed and provided to the number of people who participated in the bid, the amount may vary depending on the number of people who participated in the bid. Of course, these differences can be changed in various ways through programs set according to the service policy of the company (or business) providing the service, but above all, in the embodiment of the present invention, the buyer can receive a refund of a portion of the bid amount, such as points or virtual currency, paid to participate in the bid, and the amount may also differ depending on the number of bidders.

On the other hand, the buyer who has made a successful bid can enter into a contract with the seller according to the service provided by the real estate buyer selection device (4030) through the buyer terminal (4010). Of course, such a contract is usually made offline, for example, under the intervention of a broker, but in the embodiment of the present invention, it is also possible to make it online according to a preset program. For example, a typical example is receiving a signature on a contract through an electronic signature. Above all, the center can provide a service in which the seller, buyer, and broker form a group in the form of a group chat room through an artificial intelligence (AI) chatbot, or more precisely, a messenger-style chatbot service, and proceed with the contract through chatting, etc., and also register and sign necessary documents through the chatbot service, and the buyer can participate in this operation through the buyer terminal (4010). Of course, in the process of using a chatbot service, a touch operation may be made on the screen for a contract, or the buyer may utter a voice command, which may be received by a microphone or the like on the terminal and recognized by a voice recognition module to process the service. Therefore, the embodiment of the present invention will not be particularly limited to any one form.

The communication network (4020) includes both wired and wireless communication networks. For example, the communication network (4020) may use or be connected to a wired or wireless Internet network. Here, the wired network includes an Internet network such as a cable network or a public switched telephone network (PSTN), and the wireless communication network includes CDMA, WCDMA, GSM, EPC (Evolved Packet Core), LTE (Long Term Evolution), Wibro, etc. Of course, the communication network (4020) according to the embodiment of the present invention is not limited thereto, and may be used, for example, in a cloud computing network under a cloud computing environment, a 5G network, etc. For example, if the communication network (4020) is a wired communication network, an access point within the communication network (4020) can connect to a telephone exchange, etc., but if it is a wireless communication network, data can be processed by connecting to an SGSN or GGSN (Gateway GPRS Support Node) operated by a communication company, or data can be processed by connecting to various relays such as a BTS (Base Transmissive Station), NodeB, or e-NodeB.

The communication network (4020) may include an access point (AP). The access point here includes a small base station such as a femto or pico base station that is often installed inside a building. The femto or pico base station is classified according to the maximum number of seller terminals (4000) and buyer terminals (4010) that can be connected to the small base station. Of course, the access point may include a short-range communication module for performing short-range communication such as Zigbee and Wi-Fi with the seller terminal (4000) and buyer terminal (4010). The access point may use TCP/IP or RTSP (Real-Time Streaming Protocol) for wireless communication. Here, the short-range communication may be performed in various standards such as Bluetooth, Zigbee, infrared, RF (Radio Frequency) such as UHF (Ultra High Frequency) and VHF (Very High Frequency) in addition to Wi-Fi, and ultra-wideband communication (UWB). Accordingly, the access point can extract the location of the data packet, designate the best communication path for the extracted location, and transmit the data packet along the designated communication path to the next device, such as a real estate buyer selection device (4030). The access point can share multiple lines in a general network environment, and includes, for example, a router, a repeater, and a repeater.

The real estate buyer selection device (4030) may be called a real estate transaction service device and may be configured as a server, for example. The real estate buyer selection device (4030) enables the sale of real estate at a desired time for the seller, and provides a service in which the seller determines an appropriate sale price and period and, accordingly, multiplies the price by a flexible setting rate to disclose the property for sale. Here, the "flexible setting rate" may be regarded as a preset rate for setting the bid price and, further, the number of bidders according to the sale price. Accordingly, this rate may vary depending on the sale price, and in the embodiment of the present invention, it is named "flexible" because it is automatically recognized and set by the system or program. In addition, the real estate buyer selection device (4030) allows people who have difficulty in purchasing a home due to expensive real estate issues to pay a small amount of bid money and make a bid for real estate items, for example, items listed on a website. This allows sellers to sell their properties at a reasonable price within the period they wish to sell, and provides buyers with the opportunity to select from a variety of properties to suit their tastes and acquire them at a low price.

More specifically, the real estate buyer selection device (4030) provides a service for selling expensive real estate online without having to visit each local brokerage office when selling real estate. For example, if the selling price is 100 million won, and the real estate buyer selection device (4030) applies a setting fee multiplied by the selling price Х 1/10,000 according to the program design, the bid amount becomes 10,000 won. If the bid amount is set to 10,000 won and the set number of people is set to 100%, the set number of people is 10,000, and if it is set to 150%, the set number of people is automatically set to 15,000, so that the number of buyers changes in various ways. If the number of buyers is met for a certain period of time, a buyer is selected for a certain period of time. At this time, the selection method can be variously given, such as a 256-bit algorithm extraction method or a random arrow shooting method as mentioned above. In addition, in a system including a real estate buyer selection device (4030), the set amount and set number of people can be determined and the period can be designated, so real estate can be sold without wasting time waiting for a buyer through a brokerage or internet company as in the existing real estate selling method. Buying bidding members can choose a real estate that suits them with a small amount of money and are given the opportunity to purchase it for a small amount of money, which is usually the selling price × (1/100 to 1/∞), which is cheaper than the cost of purchasing real estate through other auction bidding.

The real estate buyer selection device (4030) can process real estate seller membership registration and exclusive contracts such as trust registration through the website. In addition, the real estate buyer selection device (4030) can determine the seller's selling price Х setting fee adjustment (e.g. selling price × (1/100 ~ 1/∞) autonomous and delegated method. For example, in the case of a sale of 100 million won, the bidding amount can be set to an infinite number of values such as 10 won ~ 1 million won. The administrator of the real estate buyer selection device (4030) can set it manually, but it can also be set automatically through a preset program. Alternatively, the setting can be performed automatically by applying artificial intelligence deep learning, etc. in performing such setting, and the setting information can be changed based on the progress of the auction, etc. In other words, performing artificial intelligence learning can be representatively seen as automatically lowering the bidding amount if it is determined that the first round was unsuccessful, i.e., if it is learned.

The real estate buyer selection device (4030) can also determine the bid number setting fee according to the selling price setting fee when the bidding amount is determined. In the case of the setting fee, it can also be determined in the form of the selling price setting fee × (1/1 ~ 1/∞). For example, if the selling price setting fee (or bidding price) is 10,000 won, the number of bidders can be set to an infinite number, such as 100 to 100,000 people. More precisely, it can be set infinitely.

When this process is completed, the real estate buyer selection device (4030) generates various bid amounts and set numbers for each real estate seller and property, allows the purchasing bidding member to purchase virtual currency when bidding, grants a unique number, and returns the entire bid amount if the designated number of people is not met within a certain period of time. In addition, the real estate buyer selection device (4030) selects one of the purchasing bidding members, for example, by the lottery method mentioned above, and incurs an opportunity cost in the form of a commission for the remaining bidding members. After this, the real estate buyer selection device (4030) can support one-stop services (legal, tax, etc.) such as registration transfer and taxes (e.g., acquisition tax, capital gains tax, unearned income tax) so that a normal real estate sales contract between the seller and the successful purchaser can proceed. One-stop service means that all tasks related to real estate transactions can be processed in one place online. The detailed operation of the real estate buyer selection device (4030) that communicates with the seller terminal (4000) and the buyer terminal (4010) is well illustrated in Fig. 12.

For example, the real estate buyer selection device (4030) may recommend a legal, tax, etc. agent based on the area where the buyer resides, or in this case, contact may be made with an agent through an online service, and may be linked to a tax office or registration office based on an API (Application Programming Interface) to enable submission of documents and payment of taxes, etc. In other words, in order to provide a one-stop service, the real estate buyer selection device (4030) may design a program linked to a server of a tax office or registration office, and may present a web service screen to a seller terminal (4000) or a buyer terminal (4010) through this to enable a one-stop service.

The third-party device (4030) includes various devices such as government offices that operate in conjunction with the real estate buyer selection device (4030). The third-party device (4030) may include a registry office server that processes real estate registration, a tax office server that processes work related to taxes for real estate transactions, and a payment server of a payment company that operates in conjunction with a payment module installed inside when purchasing virtual currency using a credit card pre-registered in the real estate buyer selection device (4030). These servers are linked by API. Accordingly, when the real estate buyer selection device (4030) provides previous documents for real estate registration online according to API linkage, the tax office server can process them, and when taxes are paid, the tax office server can provide related documents and payment information. In this way, the real estate buyer selection device (4030) can provide a one-stop service related to real estate transactions in one place, i.e., an online service, through API linkage. In other words, you can complete real estate transactions, contracts, registration transfers, and tax payments all in one site, reducing or eliminating the hassle of having to visit multiple sites or visit offline.

In summary, the buyer terminal (4010) purchases points (e.g., 10,000 won to 100,000 won) on the web equivalent to a certain amount (usually 10,000 won to 100,000 won), searches for properties that suit his or her taste, and then selects a specific property to bid on, i.e., participates. At this time, the bid amount can be an amount multiplied by 1/10,000 to 1/10,000 of the selling price. For example, if an apartment worth 300 million won is listed, 10,000 won multiplied by 1/30,000 becomes the purchase bid amount, and 10,000 points becomes the purchase bid point score. At this time, if the number of bidders is limited to 50,000, the total bid amount becomes 500 million won, and one of the 50,000 people is selected by lottery, and the successful bidder and the seller enter into a sales contract.

At this time, the selling price of 300 million won is paid from the total bidding amount (500 million won), and the remaining balance of 170 million won, excluding 10% of the selling price [total (500 million won) = selling price (300 million won) + 10% commission (30 million won)], is divided fairly among the unsuccessful bidders. Accordingly, the purchasing bidders pay 10,000 won in points to obtain the 300 million won real estate, and when they are eliminated, they usually spend 30% to 60% of the points as a participation fee, and the remaining difference in points is returned.

The successful bidder enters into a sales contract with the seller either offline through the member brokerage that registered the property or, in an embodiment of the present invention, through a one-stop service provided. The seller's capital gains tax and the successful bidder's acquisition tax incurred here are processed in the same manner as in a normal sales contract, and due to the nature of the real estate lottery sale according to the embodiment of the present invention, the successful bidder also bears the burden of unearned income tax.

Accordingly, one property registered in the real estate lottery sales method according to the embodiment of the present invention is usually processed within a period of one month, and the tax and legal processes in this process are also carried out transparently, thereby providing an innovative real estate sales method to everyone who is in conflict due to real estate.

In addition, in terms of the lottery method and management, the lottery sales method according to the embodiment of the present invention assigns a unique number (e.g., the last digits of the resident registration number, etc.) to the purchasing bidders in order to extract the purchasing successful bidders, enters into a business agreement with an internet or cable broadcasting company, etc., and selects the purchasing successful bidders through a public live broadcast at a specific time (usually Saturday morning, etc.) using a 256-bit algorithm extraction method or a random method such as an arrow shooting method to ensure a fair and transparent lottery.

Additionally, to ensure the reliability of this live broadcast, police officers, employees of related organizations, and prospective bidders may be selected to attend.

Figure 13 is a block diagram showing the detailed structure of the real estate buyer selection device of Figure 11.

As illustrated in FIG. 13, the real estate buyer selection device (4030) of FIG. 11 according to another embodiment of the present invention includes part or all of a communication interface unit (5000), a control unit (5010), a real estate buyer selection unit (or a real estate transaction processing unit) (5020), and a storage unit (5030).

Here, the term “including some or all” means that some components, such as the storage unit (5030), may be omitted to configure the real estate buyer selection device (4030), or some components, such as the real estate buyer selection unit (5020), may be integrated into other components, such as the control unit (5010), and is described as including all in order to help a sufficient understanding of the invention.

The communication interface (5000) communicates with at least one of the seller terminal (4000) and the buyer terminal (4010) via the communication network (4020) of Fig. 11. The communication interface unit (5000) can perform various operations such as modulation/demodulation, muxing/demuxing, encoding/decoding, and scaling to convert resolution during the communication process, and since this is obvious to those skilled in the art, further description thereof will be omitted.

The communication interface unit (5000) can selectively provide a service screen of the website upon a service request before or after the member registration of the seller terminal (4000), through which the seller of the seller terminal (4000) can perform an operation for registering his/her real estate listing. For example, the screen can be viewed before the member registration. In addition, a specific screen for participating in a bid can be provided after the member registration. In the process of registering a listing, information related to an appropriate selling price can be provided, and a period for requesting a sale can be registered. Of course, the communication interface unit (5000) can be involved in such an operation.

In addition, the communication interface unit (5000) communicates with the buyer terminal (4010) of Fig. 11 so that the buyer, or more precisely, the bidder (i.e., the participant participating in the bidding) who bids or responds to the real estate listing registered by the seller can purchase currency such as virtual currency to bid on a specific listing after registering as a member. To this end, a payment method such as a credit card can be registered when registering as a member, and the purchase of the virtual currency can be made through the registered credit card. Of course, for this purpose, the communication interface unit (5000) can be connected to an external payment server, etc., at the request of the control unit (5010) to proceed with the payment.

In addition, the communication interface unit (5000) can perform various operations according to the request of the control unit (5010), and can participate in additional operations such as notifying details related to the drawing of a bid item, notifying a message related to the successful bid via text message (SMS) or messenger in the case of a successful bid, and further, in the case of a successful bidder, allowing a contract to be concluded through an AI chatbot service, etc. Here, the AI chatbot service is a combination of AI technology and messenger-based chatbot technology, and is characterized by the fact that the AI robot for chatting recognizes the text content or status of the seller and the buyer and automatically operates to perform the appropriate next procedure. For example, when it is the buyer's turn to sign but there is no signature, a text requesting the buyer's terminal (4010) to sign can be transmitted through the chatbot service. Through this, the text can be displayed on the screen of the buyer's terminal (4010).

The control unit (5010) may include a processor such as a CPU, an MPU, a GPU, etc., and is responsible for the overall control operation of the communication interface unit (5000), the real estate buyer selection unit (5020), and the storage unit (5030) of FIG. 13. For example, the control unit (5010) may control the real estate buyer selection unit (5020) so that a real estate transaction service according to an embodiment of the present invention is performed, execute a program installed therein, and provide a service screen to the seller terminal (4000) and the buyer terminal (4010). Of course, the service screen here may be information related to real estate that sellers intend to sell through the buyer terminal (4010). The sale price or period information may be disclosed.

In addition, the control unit (5010) can control the communication interface unit (5000) to temporarily store data processed by the real estate buyer selection unit (5020) in the storage unit (5030) and then systematically classify and store the data in the DB (4030a) of FIG. 11. In addition, the control unit (5010) controls the real estate buyer selection unit (5020) to execute the program according to the embodiment of the present invention so that the various operations described above can be performed when the number of bidders for a certain property is met and a drawing is conducted. For example, the drawing can be conducted through a broadcast by a separate broadcasting station, but it can be linked to the server of the broadcasting station to recognize the successful bidder for a specific property based on information (e.g., a unique number assigned upon membership registration) and execute the program of the real estate buyer selection unit (5020) based on this so that the contract can continue to proceed.

The real estate buyer selection unit (5020) is equipped with a program that runs under the control of the control unit (5010). Of course, the program may be a separately produced program to provide a service according to an embodiment of the present invention, and may basically provide a web screen such as a web service. Of course, a mobile-based application service may also be provided. On the service screen, the sale price related to the real estate listing, of course, the sale price may be determined by the seller or determined by a separate real estate appraisal company or an appraisal staff member of a company providing the service, may be disclosed, and information such as the sale period may be exposed. In addition, the bid price that can be bid on the listing may be presented.

The real estate buyer selection unit (5020) determines (or calculates) the bid amount and the number of bidders based on the determined selling price for the real estate when multiple sellers register a property to be sold through their seller terminals (4000). Of course, the determination of the bid amount and the number of bidders can be set in advance during the program design so that the program can be executed. For example, when the bid amount is 100 million won, the bid amount can be set to 10,000 won, when it is 500 million won, the bid amount can be set to 50,000 won, and the number of bidders can be set to 10,000 people (100% of 10,000 won) when it is 10,000 won, and to 50,000 people (100% of 500 million won). Therefore, the real estate buyer selection unit (5020) can automatically determine or select the bid amount and the number of bidders when the corresponding price is registered and disclose them on the service screen. Of course, this selection process can be carried out in various ways depending on the intention of the program designer, and in such a selection process, automatic selection can be carried out through artificial intelligence deep learning. For example, based on the condition of a specific property to be sold (e.g. management condition or geographical location, etc.), of course, this information can be registered by the seller or brokerage firm, but when it is a property that users like a lot or demand is expected or in such a condition, when it is judged that there will be many bids, the bid price and the number of bidders are increased, and when it is judged that the preference is low, the bid price and the number of bidders are reduced.

Of course, the real estate buyer selection unit (5020) performs an operation to select a buyer for the real estate to be sold, and for this purpose, a certain amount of bid price is automatically determined based on the selling price of the property to be sold and data set during program design is referenced to automatically determine the number of bidders. In addition, when the number of bidders is met, a separate broadcasting server can be requested to conduct a lottery. In addition, when the lottery is completed, it can be determined which user among the bidders has bid based on the user information of the lottery winners, and a contract for the real estate can be concluded. A separate message can be provided to enable the contract to be concluded offline, or a separate group room based on messenger can be created to automatically invite the seller, the buyer, and the broker to the group room, and the contract can be concluded through the group room. In this process, by applying an artificial intelligence chatbot service, the contract can be presented to the seller and the buyer, and when it is determined that there is a signature of the seller and no signature of the buyer, the artificial intelligence chatbot can recognize this and provide a chat service to the buyer to sign.

In addition, the real estate purchaser selection department (5020) can provide a one-stop service for real estate contracts. In addition to the contract conclusion process above, instead of visiting the registration office to submit the relevant documents, documents can be automatically submitted by linking to the registration office server through API, etc. In addition, tax payments can be automatically made through API linkage in the case of the tax office.

The storage unit (5030) can temporarily store various data processed under the control of the control unit (5010). For example, when data such as an image of a property and various information for property registration are received from a seller through a service screen provided to a seller or buyer, the data can be temporarily stored in the storage unit (5030) and then provided to the real estate buyer selection unit (5020) so that the property can be posted (uploaded) or disclosed through the service screen when the service screen is provided.

Meanwhile, the communication interface unit (5000), the real estate buyer selection unit (5020), and the storage unit (5030) according to the embodiment of the present invention are configured as hardware modules that are physically separated from each other, but each module may store software for performing the above operations therein and execute the same. However, the software is a collection of software modules, and each module may be formed of hardware, so there will be no particular limitation on the configuration, such as software or hardware. For example, the storage unit (5030) may be hardware, such as storage or memory. However, since it is also possible to store information (repository) in software, there will be no particular limitation on the above.

In addition to the above, the communication interface unit (5000), control unit (5010), real estate buyer selection unit (5020), and storage unit (5030) of Fig. 13 can perform various operations, and since other detailed information has been sufficiently explained above, such information will be used instead.

Meanwhile, as another embodiment of the present invention, the control unit (5010) may include a CPU and a memory, and may be formed as a single chip. The CPU may include a control circuit, an operation unit (ALU), a command interpretation unit, and a registry, and the memory may include a RAM. The control circuit may perform a control operation, the operation unit may perform an operation of binary bit information, and the command interpretation unit may include an interpreter or a compiler to convert a high-level language into machine language and vice versa, and the registry may be involved in software data storage. According to the above configuration, for example, at the beginning of the operation of the real estate buyer selection device (4030), the program stored in the real estate buyer selection unit (5020) may be copied and loaded into the memory, that is, the RAM, and then executed, thereby rapidly increasing the data operation processing speed.

FIG. 14 is a flowchart showing the operation process of the real estate buyer selection device of FIG. 11 according to another embodiment of the present invention.

For convenience of explanation, referring to FIG. 14 together with FIG. 11, a real estate buyer selection device (4030) according to an embodiment of the present invention provides a service screen of an online service for real estate transactions to a seller terminal (4000) that sells real estate and a buyer terminal (4010) that purchases or bids (or responds to bids) for real estate (S1400).

In addition, the real estate buyer selection device (4030) calculates the bid price and the number of bidders based on the sale price of the real estate to be sold provided by the seller terminal (4000) (S1410). Here, the bid price and the number of bidders can be determined in various ways, and it is clear that the product of the bid price and the number of bidders must exceed the sale price. At this time, the multiple by which it exceeds varies depending on the service policy. The bid price and the number of bidders according to the sale price can be set at a set ratio based on data set at the time of program design, and can be flexibly performed according to the sale price. As mentioned above, this process can be automatically adjusted by considering various situations of the property to be sold by applying deep learning of artificial intelligence. The method of setting the set ratio can be called a rule method in contrast to artificial intelligence.

In addition, the real estate buyer selection device (4030) distributes the remaining bidding amount, which is calculated by subtracting the selling price from the total bidding amount of the bidding possible number, to the users who did not win the bid when the real estate property is sold to a random user among the number of possible bidders by satisfying the number of possible bidders calculated within the period requested by the seller to sell the real estate (S1420).

For example, if the selling price is 100 million won, the total bid amount is 500 million won, and the total number of bidders is 50,000, the real estate buyer selection device (4030) divides the total 500 million won minus the selling price of 100 million won, or 400 million won, into equal portions among bidders other than the successful bidder, thereby deducting a portion of the bid amount as a commission and refunding the remaining amount.

For example, if the bid price was 10,000 won, you can see that the remaining amount is returned after deducting 4-5,000 won as a commission in the above manner. This can be seen as activating real estate transaction services, and above all, allowing sellers to sell real estate at their desired time and secure funds, and providing buyers with an opportunity to secure real estate at a low cost.

Meanwhile, even if all the components constituting the embodiments of the present invention are described as being combined as one or operating in combination, the present invention is not necessarily limited to such embodiments. That is, within the scope of the purpose of the present invention, all of the components may be selectively combined and operated one or more times. In addition, although all of the components may be implemented as independent hardware, some or all of the components may be selectively combined and implemented as a computer program having a program module that performs some or all of the functions combined in one or more hardware. The codes and code segments constituting the computer program may be easily inferred by a person skilled in the art of the present invention. Such a computer program may be stored in a non-transitory computer readable medium and read and executed by a computer, thereby implementing the embodiments of the present invention.

Here, the non-transitory readable storage medium means a medium that semi-permanently stores data and can be read by a device, rather than a medium that stores data for a short period of time, such as a register, cache, or memory. Specifically, the above-described programs can be stored and provided on a non-transitory readable storage medium, such as a CD, DVD, hard disk, Blu-ray disk, USB, memory card, or ROM.

Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above, and various modifications may be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims. Furthermore, such modifications should not be individually understood from the technical idea or prospect of the present invention.
