Referring to Figures 1 and 2, the real estate transaction contract automatic generation system 100 according to an embodiment of the present invention includes a real estate brokerage server 200, a seller terminal 300, a buyer terminal 400, and a plurality of private blockchains. It may be implemented in the form of a node (not shown).

The real estate brokerage server 200 registers and manages sellers and buyers as members, stores listing information, generates a listing candidate list on the buyer terminal 400, transmits it to the buyer terminal 400, and processes the received transaction. A consultation request is transmitted to the seller terminal 300, and the real estate transaction contract is created based on the received contract application without the process of receiving confirmation of consent to the contract application from the seller terminal 300 or the buyer terminal 400. It is automatically generated by a contract writing system, or transmitted to the buyer terminal or seller terminal, which is the counterparty to the transaction, to confirm consent from the seller terminal 300 or the buyer terminal 400, and whether or not the contract application is agreed to. Upon receiving, the real estate transaction contract can be automatically generated by the contract writing system based on whether or not the contract application is agreed upon and transmitted to the seller terminal 300 and the buyer terminal 400. In addition, the real estate brokerage server 200 determines property rights analysis and contract suitability based on the contract application, and if the judgment result is suitable, automatically generates a real estate transaction contract and sends the seller terminal 300 and the buyer terminal ( 400), and if the judgment result is inappropriate, information on contract impossibility can be provided to the seller terminal 300 and the buyer terminal 400. In addition, the real estate brokerage server 200 receives a request to confirm whether payment of the transaction price is safe or a request for consignment payment from the buyer terminal 400 or the seller terminal 300, analyzes whether it is safe or makes a consignment payment, and determines whether the analysis result is a risk. In this case, you can recommend non-payment or inform of the impossibility of payment, and if the analysis result is safe, you can recommend payment or make payment.

The seller terminal 300 registers listing information on the real estate brokerage server 200, negotiates transaction terms with the buyer according to a transaction consultation request received from the real estate brokerage server 200, and negotiates transaction terms based on the agreed upon transaction conditions. Fill out a contract application form and send it directly to the real estate brokerage server without the process of confirming consent, or send it to the buyer terminal 300 to request confirmation of consent, and receive the contract application form written by the buyer terminal 400. Consent can be confirmed from the seller, and an electronic signature can be performed on the real estate transaction contract automatically generated by the real estate brokerage server 200.

Here, the seller includes the lessor and the lessor's agent, and the buyer includes the lessee and the lessee's agent, and the real estate transaction contract is automatically generated, which means that it is automatically created by the contract writing system of the real estate brokerage server 200. It may include the meaning of being created. In addition, contract applications and real estate transaction contracts refer to both general contracts and electronic contracts. The only difference between the two is the presence or absence of electronic functions and the signature method, but the application procedure, service procedure and method, and contract effect are the same.

Either the seller terminal 300 or the buyer terminal 400 prepares a contract application form according to the transaction conditions agreed upon during the transaction consultation process and transmits it directly to the real estate brokerage server 200 to generate the real estate transaction contract. Alternatively, in order to further increase the safety of the transaction, the real estate transaction contract can be created by going through the process of once again confirming consent from the transaction counterparty. That is, if the contract application form is filled out at the seller terminal 300, it is sent to the buyer terminal 400, and if it is written at the buyer terminal 400, it is sent to the seller terminal 300 to request confirmation of consent, and the result is sent to the seller terminal 300. This means that a real estate transaction contract can be created by receiving it from the real estate brokerage server 200. Whether or not to go through the consent process can be selected by agreement between the seller and buyer or by transaction type, and the speed of the transaction is If required, a transmission path to the real estate brokerage server 200 can be selected, and if transaction security is required, a transmission path to the transaction counterparty can be selected. However, without being limited to this, either the seller terminal 300 or the buyer terminal 400 may prepare and apply for a contract application even when the seller and the buyer have not agreed on transaction conditions, contract application preparation, and application method. there is. However, for security reasons, contract applications written and applied for without the transaction terms being agreed upon in advance cannot be used to create a real estate transaction contract without the consent of the transaction counterparty.

The buyer terminal 400 connects to the real estate brokerage server 200, displays a list of candidate listings generated through a listing search, and sends a transaction consultation request for the candidate listing selected by the buyer to the real estate brokerage server 200. The contract application form is prepared based on the transaction terms agreed upon through negotiation with the seller and sent directly to the real estate brokerage server 200 without the process of confirming whether the consent has been given, or to the seller terminal 300. transmit to request confirmation of consent, receive the contract application form prepared by the seller terminal 300, receive confirmation from the buyer of consent, and perform an electronic signature on the real estate transaction contract automatically generated by the real estate brokerage server. You can.

The method for the buyer to request transaction consultation through the seller terminal 300 is to use a method programmed as a system to achieve the purpose by interconnecting the functions of the brokerage server and an external professional company, or by using a method of general SNS. The method of using the communication function or other general wired or wireless communication functions can be selectively used depending on the buyer's environment.

The seller terminal 300 refers to a terminal owned by a seller who wants to sell real estate, and the buyer terminal 400 refers to a terminal owned by a buyer who wants to purchase real estate.

The seller terminal 300 and the buyer terminal 400 include a smartphone, a smartpad, a Tablet PC, a Personal Communication System (PCS), a Global System for Mobile communications (GSM), and a PDC ( Personal Digital Cellular), PHS (Personal Handyphone System), PDA (Personal Digital Assistant), IMT (International Mobile Telecommunication)-2000, CDMA (Code Division Multiple Access)-2000, W-CDMA (W-Code Division Multiple Access), It includes user-portable wireless communication devices such as Wibro (Wireless Broadband Internet) terminals and portable computing devices such as stationary PCs and laptops.

The real estate brokerage server 200 communicates with the seller terminal 300, the buyer terminal 400, and a plurality of private blockchain nodes to exchange information or data with each other and is responsible for real estate brokerage. This real estate brokerage server 200 has the same configuration as a typical web server in terms of hardware, and is implemented in various types of languages such as C, C++, Java, Visual Basic, and Visual C in terms of software, and provides various functions. It may include program modules that do. In addition, general server hardware is provided in a variety of operating systems such as DOS, Windows, Linux, Unix, Macintosh, Android, and iOS. It can be implemented using an existing web server program.

An example of network communication connecting the seller terminal 300, the buyer terminal 400, the real estate brokerage server 200 and a plurality of private blockchain nodes according to this embodiment is technical standards or communication methods for mobile communication. (For example, Global System for Mobile communication (GSM), Code Division Multi Access (CDMA), Code Division Multi Access 2000 (CDMA2000), Enhanced Voice-Data Optimized or Enhanced Voice-Data Only (EV-DO), WCDMA ( Wideband CDMA), HSDPA (High Speed Downlink Packet Access), HSUPA (High Speed Uplink Packet Access), LTE (Long Term Evolution), LTE-A (Long Term Evolution-Advanced), 5G, etc.) It may be included, but is not particularly limited. Additionally, an example of a wired communication network may be a closed network such as a LAN (Local Area Network) or a WAN (Wide Area Network), and it is preferably an open network such as the Internet. The Internet uses the TCP/IP protocol and several services existing at its upper layer, namely HTTP (HyperText Transfer Protocol), Telnet, FTP (File Transfer Protocol), DNS (Domain Name System), SMTP (Simple Mail Transfer Protocol), and SNMP ( It refers to a global open computer network structure that provides Simple Network Management Protocol (NFS), Network File Service (NFS), and Network Information Service (NIS).

The seller terminal 300 and the buyer terminal 400 according to this embodiment can perform functions related to real estate purchase, sale, lease, rental, etc. by installing a dedicated app separately provided by the real estate brokerage server 200 on each terminal. there is. Here, the dedicated app may be provided through the app market of a known smartphone operating system such as the Android Store or App Store, or may be provided separately from the real estate brokerage server 200.

Referring to Figure 2, the real estate brokerage server 200 according to an embodiment of the present invention includes an information management unit 210, an interface unit 220, a listing matching unit 230, a listing confirmation unit 240, and a contract management unit ( 250), it may include at least one of a security management unit 260, a transaction amount analysis unit 270, and a property inspection unit 280.

The information management unit 210 may store seller member information, buyer member information, and property information in a database. Additionally, the information management unit 210 may store a question list including a series of questions in the database.

The interface unit 220 allows users to register listing information, search for listings, consult on transactions, fill out and agree to contract applications, and electronically sign real estate transaction contracts through a dedicated application provided to the seller terminal 300 and buyer terminal 400. An interface can be provided. As an example, the interface unit 220 may provide a chat interface when a seller and a buyer negotiate transaction conditions through the transaction consultation request. At this time, an interface is provided at the top of the chat interface to adjust the desired selling price and desired buying price among the transaction conditions with a slider, and when the other party adjusts the desired selling price or desired buying price during negotiation of transaction conditions, an animation that changes in real time is displayed on both sides. can be provided.

In addition, when the desired sale price or desired purchase price is adjusted, information on changes in incidental costs such as transfer tax, registration tax, property tax, and brokerage fees that change along with this can be provided to the seller and buyer terminals in real time.

As another example, when the seller and buyer negotiate transaction terms through the transaction consultation request, the interface unit 220 provides an application form menu for filling out the contract application, including a form applying the standard contract and the real estate brokerage. A form randomly created by the server 200 is given, and the seller terminal 300 or the buyer terminal 400 selects and fills out one of the two forms for filling out the contract application form menu, and both forms are general information. Provides an interface for writing special contracts. The general terms apply to the contents of the standard contract and can be modified and added, and the special terms allow selection, modification, and addition in whole or in part from a list of special contracts provided in advance. provided so that the real estate transaction contract can be created.

The listing matching unit 230, in conjunction with the interface unit 220, generates at least one listing candidate among a plurality of listing candidates as a listing candidate list based on the listing search of the buyer terminal 400, and matches the listing to the buyer terminal ( 400). According to one example, the listing matching unit 230 generates the listing candidate list based on the listing search of the buyer terminal 400 when the buyer terminal 400 selects a general search, or selects a customized search to create a list of candidate listings. The questions are provided one at a time, but when the answers are completed, the next question is provided. When the answers to the series of questions are completed, the list of candidate listings can be generated in order of high matching based on the answers. . Additionally, the property matching unit 230 may change the items of the next question based on the buyer's response.

For example, a question about the area in which you wish to purchase could be structured as follows. ‘Select the property search area _____ city/province’ Here, the city/province can be entered through the drop-down menu, direct input, or search interface. The next question is that if the buyer selects Seoul or Gyeonggi-do, additional questions about detailed addresses by region will be asked. ‘Please select a property search area _____-gu/county’ If the buyer selects a specific county, county, city, etc., the next question may similarly ask about additional detailed addresses. In this way, you can easily enter the desired property information by asking one simple question at a time. Even after that, additional questions may be asked about the property type, desired purchase price, etc., and, like questions about the desired purchase area, the additional questions asked may change depending on the property type. If the property type is an apartment, follow-up questions will be asked, such as whether you prefer high-rises, low-rises, individual heating, or district heating. If the property type is a multi-family residence, follow-up questions will be asked, such as whether you prefer elevators, etc. This can come out.

In this way, the listing matching unit 230 provides a series of questions one by one in connection with the interface unit 220, and changes the follow-up questions according to the buyer's response, so that the user does not have to inconveniently enter listing information one by one, but only once. User convenience can be improved by allowing only one question to be answered.

The listing matching unit 230 may analyze responses to the series of questions, generate at least one listing candidate among a plurality of listing candidates as the listing candidate list, and transmit the listing to the buyer terminal 400. That is, the listing matching unit 230 searches the listing information stored in the database based on the responses to the series of questions, selects at least one listing with a high degree of relevance as a listing candidate, and orders the listing candidates in order of high relevance. The list can be provided to the buyer terminal 400.

For example, as a result of analyzing the responses to the series of questions above, the properties searched by querying the database for property information based on information such as the area desired by the buyer, type of real estate, desired purchase price, and desired purchase date are sorted by relevance. It can be sorted and provided to the buyer terminal 400. The results of responses to a series of questions are that the new building in 00-gu, 00-dong, Seoul, was built within 0 years, has an apartment, has an underground parking lot, has parking space for more than 1.5 cars per household, and the price can be between KRW 0 billion and KRW 0 billion. Based on the response, you can create a list of candidate listings by matching the most relevant listing information in the database. In addition, the listing candidate list may be provided by selecting a variable with high priority among various variables such as price, region, and square footage according to the buyer's input, and changing the order of the listing candidate list based on that variable.

The property confirmation unit 240 may provide property information about the property candidate selected by the buyer terminal 400. More specifically, when a candidate for sale is selected by a buyer from the list of candidate for sale, the property confirmation unit 240 displays it in a photo, VR, or 3D based on the property information of the candidate for sale, even if the property is not actually visited and confirmed. You can check the property for real-time. For this purpose, the seller terminal 300 may include a 3D camera or a general camera. When the seller terminal 300 includes a general camera, the property confirmation unit 240 may generate a VR or 3D image based on the image of the property provided from the seller terminal 300. At this time, the listing confirmation unit 240 may determine whether the listing is a false listing by comparing and analyzing the listing information registered from the seller terminal 300 and the image of the listing. For example, when the listing confirmation unit 240 receives an image for a listing, it checks the EXIF information of the listing image and compares the address in the listing information with the location information in the EXIF information. If there is an error of a certain distance or more, the seller terminal ( 300), additional location verification, such as requesting location information, can be performed.

The contract management unit 250 analyzes property rights and determines contract suitability based on the contract application, and if the judgment result is appropriate, automatically creates a real estate transaction contract and sends it to the seller terminal 300 and the buyer terminal 400. , and if the judgment result is inappropriate, information on the impossibility of contracting can be provided to the seller terminal 300 and the buyer terminal 400. The contract application form contains the agreed upon transaction conditions (transaction amount, payment method, payment date, etc. ), it may consist of items such as seller and buyer information, property information, general information, and special contract information. Each item is displayed in conjunction with the information already entered in the brokerage server at the time of membership registration and listing, and if the information is changed or added by agreement between the transaction parties, the applicant must directly change or add it to the relevant item. Special contract information can be created by the seller or buyer selecting all or part of the special contract contents already indicated in the contract application, and changes or content can be added by agreement between the transaction parties. In addition, the contract management department 250 can attach the results of analyzing the rights and safety of the transaction to the real estate transaction contract. The real estate transaction contract to which this analysis result is attached can be stored in a private blockchain by the security management unit 260. Through this, the real estate transaction contract signed by the seller and buyer is safely stored in a private blockchain, avoiding the risk of hacking and personal information leakage. Additionally, the transaction terms negotiation details attached to the real estate transaction contract may include the chat history in which the transaction terms were negotiated, which can help prevent future disputes.

The transaction amount analysis unit 270 receives a request for confirmation of safety of payment of the transaction amount or a request for consignment payment from the buyer terminal 400, analyzes whether the transaction is safe or makes a consignment payment, and if the analysis result is risky, a partial payment is made. Notifies the solicitation or impossibility of payment, and if the analysis result is safe, the solicitation for payment or payment can be performed.

As described above, the security management unit 260 can verify real estate transaction contracts electronically signed from the seller terminal 300 and the buyer terminal 400 and store them in a private blockchain. To this end, the real estate brokerage server 200 can exchange data in connection with a plurality of private blockchain nodes and an external certification authority server through a network.

The listing inspection unit 280 performs document verification for the listing candidate based on the API provided by the Internet registry office, and performs document verification on the listing candidate based on the results of the existence verification performed offline or online by the verifier. You can judge whether it is genuine or not.

Hereinafter, a method for automatically generating a real estate transaction contract according to an embodiment of the present invention will be described with reference to FIGS. 3A to 5.

3A to 3B, the method of automatically generating a real estate transaction contract according to an embodiment of the present invention includes the step of registering property information with the real estate brokerage server 200 by the seller terminal 300 (S110). Verifying and storing the property information by the real estate brokerage server 200 (S115), connecting to the real estate brokerage server 200 and searching for the property by the buyer terminal 400 (S120), Step of providing a listing search interface to the buyer terminal 400 by the real estate brokerage server 200 (S125), displaying a listing candidate list generated through a listing search by the buyer terminal 400 ( S130), transmitting a transaction consultation request for the property candidate selected by the buyer to the real estate brokerage server 200 by the buyer terminal 400, and negotiating transaction terms with the seller (S135), the seller terminal (300) or by the buyer's terminal (400), a contract application form is prepared (S140) based on the transaction terms agreed upon through negotiation of the transaction terms and sent directly to the real estate brokerage server (200) without the process of confirming consent. step, or prepare the contract application form based on the transaction terms agreed upon through negotiation of the transaction terms (S140) and send the buyer terminal 400 or the seller terminal 300, which are the counterparties to the transaction, to request confirmation of consent. A step of transmitting a contract application (S145), a step of confirming whether the buyer or seller agrees to the contract application by the buyer terminal 400 or the seller terminal 300 (S150), and the real estate brokerage server 200 ), a real estate transaction contract is automatically generated based on consent to the contract application received from the buyer terminal 400 or the seller terminal 300 and sent to the seller terminal 300 and the buyer terminal 400. It may include a step of transmitting (S155) and a step of performing an electronic signature on the real estate transaction contract by the seller terminal 300 and the buyer terminal 400 (S160).

In the step (S110) of registering property information with the real estate brokerage server 200 by the seller terminal 300, when the real estate brokerage server 200 provides a series of questions, the seller provides property information by responding to them. You can register. This can be performed similarly to the item matching unit 230 providing a series of questions to the buyer terminal 400 in connection with the interface unit 220. The property matching unit 230 generates questions based on a question list containing a series of questions stored in the information management unit 210 and provides a series of questions one at a time, but provides the next question when the answers are completed. You can provide questions with . Additionally, the items in the following questions can be changed based on the seller's response.

For example, a question about a property you wish to sell may be structured as follows. ‘Select the location of the property you wish to register _____ City/Province’ Here, the city/province can be entered through the drop-down menu, direct input, or search interface. The next question is that if the seller selects Seoul or Gyeonggi-do, additional questions about detailed addresses by region will be asked. ‘Please select the location of the property you wish to register _____-gu/county’ If the seller selects a specific county, county, city, etc., the next question may similarly ask about additional detailed addresses. In this way, you can easily enter information about the property you wish to register by asking one simple question at a time. Even after that, additional questions may be asked about the property type, desired selling price, etc., and the additional questions asked may change depending on the property type. If the property type is an apartment, follow-up questions may be asked, such as whether it is a high or low-rise building and whether there is individual heating. If the property type is a multi-family house, follow-up questions may be asked, such as whether there is an elevator, etc. After property information is entered through a series of questions, uploading additional property images may be requested. Accordingly, when the seller uploads a property image, the property confirmation unit compares the location information confirmed through EXIF information in the uploaded property image with the address in the property information, and if there is an error of a certain distance or more, a request for location information from the seller's terminal 300 is made. Verification can be performed for the same additional locations.

In the step S115 of storing the listing information by the real estate brokerage server 200, the listing information may be stored in a database through the information management unit 210.

In the step (S120) of accessing the real estate brokerage server 200 and searching for properties by the buyer terminal 400, the buyer terminal 400 can select a general search or a customized search.

In the step (S125) of providing a listing search interface to the buyer terminal 400 by the real estate brokerage server 200, when the buyer selects a general search, a list of candidate listings is provided based on the listing search of the buyer terminal 400. If you create a search or select a custom search, a series of questions will be provided one at a time, and once the answers are complete, the next question will be provided, and once the answers to the series of questions are completed, the order of highest matching is based on the answers. The list of candidate listings can be created as described above.

If a customized search is selected, for example, questions about the area in which you wish to purchase may be structured as follows. ‘Select the property search area _____ city/province’ Here, the city/province can be entered through the drop-down menu, direct input, or search interface. The next question is that if the buyer selects Seoul or Gyeonggi-do, additional questions about detailed addresses by region will be asked. ‘Please select a property search area _____-gu/county’ If the buyer selects a specific county, county, city, etc., the next question may similarly ask about additional detailed addresses. In this way, you can easily enter the desired property information by asking one simple question at a time. Even after that, additional questions may be asked about the property type, desired purchase price, etc., and, like questions about the desired purchase area, the additional questions asked may change depending on the property type. If the property type is an apartment, follow-up questions will be asked, such as whether you prefer high-rises, low-rises, individual heating, or district heating. If the property type is a multi-family residence, follow-up questions will be asked, such as whether you prefer an elevator or not. This can come out.

In the step (S130) of displaying a list of candidate listings generated through a listing search by the buyer terminal 400, when a general search is selected, a list of candidate listings is generated based on the listing search of the buyer terminal 400. When display or customized search is selected, responses to a series of questions are analyzed to generate at least one listing candidate among a plurality of listing candidates as the listing candidate list and transmitted to the buyer terminal 400. That is, based on the responses to a series of questions, the listing information stored in the database is searched, at least one listing with a high correlation is selected as a listing candidate, and the listing candidate list is sent to the buyer terminal 400 in order of high relevance. can be provided.

For example, as a result of analyzing the responses to the series of questions above, the properties searched by querying the database for property information based on information such as the area desired by the buyer, type of real estate, desired purchase price, and desired purchase date are sorted by relevance. It can be sorted and provided to the buyer terminal 400. The results of responses to a series of questions are that the new building in 00-gu, 00-dong, Seoul, was built within 0 years, has an apartment, has an underground parking lot, has parking space for more than 1.5 cars per household, and the price can be between KRW 0 billion and KRW 0 billion. Based on the response, you can create a list of candidate listings by matching the most relevant listing information in the database. In addition, the listing candidate list may be provided by selecting a variable with high priority among various variables such as price, region, and square footage according to the buyer's input, and changing the order of the listing candidate list based on that variable.

In addition, when a candidate for sale is selected by a buyer from the list of candidates for sale, it is displayed in VR or 3D based on the property information of the candidate for sale, so that the property can be confirmed realistically even without actually visiting the property in question. For this purpose, the seller terminal 300 may include a 3D camera or a general camera. When the seller terminal 300 includes a general camera, the property confirmation unit 240 may generate a VR or 3D image based on the image of the property provided from the seller terminal 300. At this time, it is possible to determine whether the property is a false property by comparing and analyzing the property information registered from the seller terminal 300 and the image of the property. For example, when the listing confirmation unit 240 receives an image for a listing, it checks the EXIF information of the listing image and compares the address in the listing information with the location information in the EXIF information. If there is an error of a certain distance or more, the seller terminal ( 300), additional location verification, such as requesting location information, can be performed.

In the step (S135) of transmitting a transaction consultation request for the property candidate selected by the buyer to the real estate brokerage server 200 by the buyer terminal 400 and negotiating transaction conditions with the seller (S135), the seller terminal 300 And through a dedicated application provided to the buyer terminal 400, a user interface for registration of property information, search for properties, transaction consultation, and electronic signature of a real estate transaction contract may be provided. Accordingly, a user interface for requesting transaction consultation may be provided. You can negotiate transaction terms with the seller.

For example, when a seller and a buyer negotiate transaction terms through a transaction consultation request, a chat interface may be provided. At this time, an interface is provided at the top of the chat interface to adjust the desired selling price and desired buying price among the transaction conditions with a slider, and when the other party adjusts the desired selling price or desired buying price during negotiation of transaction conditions, an animation that changes in real time is displayed on both sides. can be provided.

In addition, when the desired sale price or desired purchase price is adjusted, information on changes in incidental costs such as transfer tax, registration tax, property tax, and brokerage fees that change along with this can be provided to the seller and buyer terminals in real time.

Step (S145) of preparing a contract application form by the seller terminal 300 or the buyer terminal 400 based on the transaction terms agreed upon through negotiation of the transaction terms (S140) and transmitting it to the real estate brokerage server 200 (S145) In, the interface unit 220 provides an application form menu for filling out a contract application, where a form applying the standard contract and a form arbitrarily produced by the real estate brokerage server 200 are given, and the seller terminal 300 or The buyer terminal 400 selects and fills out one of the two forms for filling out the contract application form. Both forms provide an interface for writing general information and special provisions, but the contents of the standard contract apply to the general information. Modification and addition are possible, and the special contract is provided so that all or part of the special contract list can be selected, modified, or added in advance, so that the real estate transaction contract can be created.

The step (S145) of transmitting the contract application from the seller terminal 300 or the buyer terminal 400 to the buyer terminal 400 or the seller terminal 300 before being transmitted to the real estate brokerage server 200 (S145) is a contract. If the other terminal that did not fill out the application form (S140), i.e., the terminal that filled out the contract application form, is the seller terminal (300), the contract is contracted as the buyer terminal (400), and if the terminal that filled out the contract application form is the buyer terminal (400), the contract is contracted as the seller terminal (400). This means that the purpose is to further increase the safety of the transaction by sending the application and confirming the contents of the contract application to the transaction counterparty.

In the step (S150) of receiving confirmation from the buyer or seller whether they agree to the contract application by the buyer terminal 400 or the seller terminal 300, the buyer terminal 400 or the seller terminal 300 submits the contract application. This means that it is the seller's terminal 300 or the seller's terminal 400, which is the other party to the transaction, and not the terminal that created it. That is, the seller or buyer who wrote the contract application sends it to the buyer or seller who did not fill out the application, checks whether the contents of the contract application match the agreed transaction conditions, and then transmits it from the terminal to the real estate brokerage server 200 to purchase real estate. This means creating a transaction contract.

Referring to FIG. 4, the real estate brokerage server 200 automatically generates a real estate transaction contract based on consent to the contract application received from the buyer terminal 400 or the seller terminal 300. The step of transmitting to the seller terminal 300 and the buyer terminal 400 (S155) is a step of analyzing property rights and determining contract suitability based on the contract application by the real estate brokerage server 200 (S151), and It further includes a step of automatically generating the real estate transaction contract by the real estate brokerage server 200 if the determination result is suitable (S155), or providing contract impossibility information to the seller terminal and buyer terminal if the determination result is inappropriate (S152). This can be done, and it can be said that the above steps are naturally included in the procedure carried out without the process of requesting confirmation of consent to the contract application. Whether or not to go through the process of requesting consent to the contract application can be selected by agreement between the seller and buyer or by transaction type. If speed of transaction is required, the transmission path to the real estate brokerage server 200 is selected. , if transaction security is required, you can select the transmission path to the transaction counterparty.

When automatically generating a real estate transaction contract by the real estate brokerage server 200, the real estate transaction contract can be automatically generated based on the contract application form. For this purpose, a pre-saved real estate standard contract template can be loaded and the items in the contract application form can be automatically entered. Therefore, if the seller and buyer only agree on the transaction terms and fill out and agree to the contract application, they can automatically generate and receive a real estate transaction contract, and the process is carried out without the seller and buyer confirming whether they agree to the contract application. If you agree in advance, you can create and receive each of the above real estate contracts regardless of the process of receiving consent. In this case, the same services apply to the process of analyzing the rights of the property and determining whether it is safe, as well as the process after electronic signature.

In the step of performing an electronic signature on the real estate transaction contract by the seller terminal 300 and the buyer terminal 400 (S180), the seller and the buyer each perform an electronic signature on the received real estate transaction contract. The real estate brokerage server 200 can verify the electronic signature in connection with an external certification agency. In the step (S151) of analyzing property rights and determining contract suitability based on the contract application, the real estate brokerage server 200 conducts a rights analysis of the property in question and determines whether the contract is suitable in connection with an external verification agency or an organization that provides public data and legal data. Based on the above-agreed transaction conditions, property-related documents provided by external verification agencies or public data and legal data providers (courts, Ministry of Land, Infrastructure and Transport, Ministry of the Interior and Safety, etc.), and the actual existence of properties for sale using an online location information system or offline, etc. Real estate experts, such as real estate agents, can perform property rights analysis and determine contract suitability. In this process, if the judgment result is appropriate, the real estate transaction contract can be automatically generated, or if it is inappropriate, information on contract impossibility can be provided to the seller terminal 300 and the buyer terminal 400. At the same time, the real estate brokerage server 200 may return to the step of displaying the list of candidate items for sale on the buyer terminal 400 (S130) and provide the list of candidate items for sale. At this time, the property that has received information that a contract is not possible can be excluded from the list.

Referring to FIG. 5, after the step (S160) of performing an electronic signature on the real estate transaction contract by the seller terminal 300 and the buyer terminal 400, the safety of the transaction price is confirmed or the consignment payment is determined. It shows the process.

The process of confirming the safety of the transaction price or determining whether to make a consignment payment is performed after the step (S160) of performing an electronic signature on the real estate transaction contract by the seller terminal 300 and the buyer terminal 400. The server 200 receives a request for confirmation of whether payment of the transaction price is safe or a request for consignment payment from the buyer terminal 400 or the seller terminal 300, and analyzes (S161) whether it is safe or makes consignment payment. If the result is dangerous, it may include a step (S165) of recommending payment or notifying the inability to pay, and if the analysis result is safe, recommending payment or performing payment.

In the process of checking whether the transaction amount is safe or making a consignment payment, the real estate brokerage server 200 analyzes whether the transaction amount is safe or makes a consignment payment in conjunction with an external agency, and makes payments according to the analysis results. /Can perform non-payment recommendation or payment/non-payment. If the analysis result is a risk, the real estate brokerage server 200 may return to the step of displaying a list of candidate items for sale on the buyer terminal 400 (S130) and provide a list of candidate items for sale. At this time, the property that has received a non-payment recommendation or an inability to pay can be excluded from the list.

Referring to FIGS. 6A and 6B, the interface unit 220 in the automatic real estate transaction contract generation system 100 provides a chat interface when a seller and a buyer negotiate transaction conditions. When the seller and buyer negotiate transaction terms through a transaction consultation request, the interface unit 220 can negotiate face-to-face offline or use a chat interface. At the top of the chat interface, the desired selling price and the desired selling price among the transaction conditions are displayed. An interface for adjusting the desired purchase price using a slider can be provided. Additionally, the interface unit 220 can provide an animation that changes in real time to both sides when the other party adjusts the desired selling price or desired buying price during negotiation of transaction conditions, as shown in FIG. 6B.

For example, when checking listing information for a listing candidate selected by a buyer from the listing candidate list and requesting transaction consultation, a chat interface is provided for negotiating transaction conditions with the seller. When parties want to change their transaction terms through chat, they can adjust the slider at the top, and this process can be reflected and displayed in animation form on both terminals in real time. Whether or not the transaction terms are agreed upon can be determined by both parties adjusting their own sliders. If both sliders are located at the same point, the amount corresponding to that position can become the agreed upon transaction terms. However, the agreed upon transaction terms are not limited to the amount, and transaction conditions for transaction date, down payment, etc. may be provided in the form of an additional slider interface, and negotiations can be judged to be complete only when all transaction conditions match.

In addition, when the transaction amount is adjusted as shown in Figure 6a among the transaction conditions, information on changes in incidental costs such as transfer tax, registration tax, property tax, and brokerage fees that change along with this is sent to the seller terminal 300 and the buyer terminal 400 in real time. can be provided.
