Description

Technical Field

[0001] The present invention relates to a real estate trading system.

Background Art

[0002] In recent years, it has become possible to buy and sell studio apartments (hereinafter referred to as properties) via the Web. When selling or buying a property, the seller wants to sell it under the best possible conditions with no risk. Also, the buyer wants to purchase it at the lowest possible price.

[0003] It is mainstream to search for properties that meet such conditions and send information to the seller or the buyer. For example, Patent Document 1 is disclosed. This Patent Document 1 aims to eliminate the need for a real estate agent to accompany the property information and provide a detailed explanation thereof, and its solution means is as follows.

[0004] A real estate transaction support system including a server, a seller terminal for use by a seller connected to the server via an Internet system, and a plurality of buyer terminals for use by buyers connected to the server via the Internet system, the system comprising: property information registration means for registering property information regarding a property provided via the seller terminal; buyer information registration means for registering information regarding a buyer provided via the seller terminal; property information display means for displaying a main part of the registered property information; chat permission means for enabling dialogue by e-mail between the seller-side terminal and the buyer-side terminal; and property guidance application means for the seller-side terminal to request guidance to a property related to the above property information.

[0005] The origin of real estate agency fees is the brokerage contract. Based on this brokerage contract, the real estate agency obtains income from the buyer (lessee) and the seller (lessor). Currently, many consumers are often unaware of the existence of this brokerage contract. For real estate agents, especially in the case of buyers (lessees), it is almost never the case that a brokerage contract is concluded from the very beginning of property search. This is because consumers are hesitant to affix their seals when they are not even sure if they will decide to buy (lease) the property, and since agents are aware of such reactions from buyers (lessees), they do not bring up the matter of the brokerage contract so as not to drive away potential customers.

[0006] First of all, property search is often conducted through flyers of real estate companies, information magazines, etc. At the stage of inquiring with a real estate company about a property in a flyer, it is often the case that the brokerage contract is not reached for the reasons mentioned above. Therefore, generally for buyers (lessees), when they find a good property and are informed of the existence of the brokerage contract just before the transaction, they often conclude a brokerage contract with the brokerage company that introduced the property.

Mode for Carrying Out the Invention

[0019] Hereinafter, each embodiment will be described in detail with reference to the accompanying drawings. In this example, descriptions of technologies that are already known will be omitted. Also, the devices and methods for embodying the technical idea of the invention are merely examples, and the technical idea of the present invention is not limited to the following. The technical idea of the present invention can be variously modified within the scope of the matters described in the claims. In particular, it should be noted that the drawings are schematic and different from the actual ones.

[0020] FIG. 1 is a schematic configuration diagram of the real estate trading system 1 of this embodiment. As shown in FIG. 1, the real estate trading system 1 is connected via a communication network 30 (such as the Internet) to a seller terminal 10 (a personal computer or a smartphone), a buyer terminal 20 (a personal computer or a smartphone), a judicial scrivener's personal computer 40, a financial institution system 50, a property trading site 100, etc.

[0021] The property trading site 100 (composed of a computer system) is composed of a property trading support server 101, a site-side terminal 200, etc. The property trading support server 101 is composed of a membership registration section 110, an auction processing section 120, a re-listing processing section 130, etc. By providing these respective sections, this system auctions a studio apartment, matches the respective conditions between the seller and the buyer, and the property trading site 100 substitutes for the troublesome process up to the settlement.

[0022] The membership registration section 110 registers membership registration information. The membership registration information includes that of the seller and the buyer, and identification codes such as general member information, silver member information, gold member information, platinum member information, etc. (collectively referred to as the level of excellence) are assigned to the members. Note that the brokerage contract information is stored in association with the member information.

[0023] Specifically, the seller's membership registration information (also simply referred to as seller information) consists of the seller's name, phone number, account, email address, account information (including credit), registration date, etc. The seller's membership registration information is associated with the property for sale condition information. The property for sale condition information includes the seller's name, account, property address, property environment, property images (still images, videos), expected selling price, year of construction, etc.

[0024] Also, the buyer's membership registration information (also simply referred to as buyer information) consists of the buyer's name, phone number, account, email address, account information, registration date, etc.

[0025] The buyer's membership registration information is associated with the property purchase condition information. The property purchase condition information includes the buyer's name, account, expected purchase price, purchase conditions, year of construction, etc.

[0026] In this embodiment, the property purchase condition information and the property for sale condition information are collectively referred to as provisional property transaction information. Furthermore, the membership registration unit 110 has means for storing the seller's property for sale condition information or the buyer's property purchase condition information as property transaction information in the memory and assigning a goodness degree based on this property transaction information, means for providing a screen for registering the property for sale condition information to the seller terminal 10, means for providing the property for sale condition information to the buyer terminal 20, etc.

[0027] The auction processing unit 120 provides the property registration information for which transactions are possible to the real estate auction site and causes the auction site to return the winning bid price information to the property transaction site 100. The re-listing processing unit 130 receives the seller's property for sale condition information or the buyer's property purchase condition information from the seller terminal 10 or the buyer terminal as property transaction information, and has means for storing this property transaction information as provisional property transaction information for a certain period, means for auctioning the provisional property transaction information as property information for which transactions are possible, etc.

[0028] The aforementioned certain period is included in the brokerage contract information, and this brokerage contract information is within the range that does not exceed the agency contract regarding the listing deadline (however, the upper limit is 3 months).

[0029] Referring to FIGS. 2 to 23, the overall schematic operation of the real estate trading system 1 will be described with reference to the smartphone screens (seller terminal 10 and buyer terminal 20).

[0030] FIG. 2 is the initial screen G1 of the real estate trading system 1, and the heading of "One-room Apartment Auction System" is displayed. On the screens G2 and G3 of FIG. 2, the tutorial of this system is displayed. For example, explanations such as "Safe and Secure Sale Support" and "Purchase Experience Like Never Before" are displayed. That is, no groundless intermediaries are involved. Information such as no margin is generated is displayed on the seller terminal 10 and the buyer terminal 20. Although omitted in the following description, the screen G is displayed on the seller terminal 10 and the buyer terminal 20. The property trading site 100 controls the display execution.

[0031] After understanding this tutorial, the buyer taps the "Want to Buy" button displayed on the screen G4 of FIG. 2. The "Want to Sell" of the seller will be described later.

[0032] Referring to FIG. 3. The screen G5 of FIG. 3 is the dashboard, and the basic screen is displayed. When the "Want to Buy" button is selected, it transitions to the screen G6 of FIG. 3. A plurality of properties registered for sale are displayed on the screen G6 of FIG. 3. The buyer taps and selects the property that the buyer hopes to buy.

[0033] Referring to the screen G7 of FIG. 3 to the screens G8 to G10 of FIG. 4. It is the detailed information screen of the selected property. It is the content appraised by the property trading site 100, and information on the content generally displayed as real estate is displayed (for example, address, nearest station, distance from the station, etc.).

[0034] Also, when viewing the rent, the buyer needs to input the input items (e-mail address, password, etc.) shown on the screen G11 of FIG. 5 and log in.

[0035] Based on this login, as shown in the screens G12 of FIG. 5 to the screens G13 to G15 of FIG. 6, information such as the tenant's rent is displayed on the buyer terminal 20 on the buyer side so that it can be viewed.

[0036] If the buyer is satisfied, tap the "Bid" button on screen G15 in Figure 6. At this timing, the screen transitions to screen G16 in Figure 7, and a pop-up menu for identity verification appears, allowing you to enter whether identity verification (for example, you may use identity verification for eKYC (online identity verification)) can be performed.

[0037] As shown in screen G17 of Figure 7, select whether the buyer is a corporation or an individual. In this embodiment, the case of an individual will be described.

[0038] When the individual button is tapped, enter the name, address, phone number, etc. from screens G18 and G19 in Figure 8 to perform identity verification. As shown in screens G20 and G21 of Figure 9, perform identity verification based on the input information from an external service (such as eKYC (electronic Know Your Customer)). As a result, bidding becomes possible, so once, return to screen G22 in Figure 9 of the dashboard.

[0039] And at the timing when the "Bid" button on screen G23 in Figure 10 is tapped, enter the bid amount from screens G24 and G25 in Figure 10.

[0040] As a result, as shown in screen G26 in Figure 10, a reply such as "Bid accepted" is displayed in the pop-up menu. Then, return to screen G27 in Figure 10 of the dashboard. Note that no winning bid is made for a certain period. This is because there may be buyers who drop out.

[0041] After that, as shown in screen G28 in Figure 11, select whether to purchase in cash or on loan. In this example, the case of using a loan will be described.

[0042] Then, as shown in screen G29 in Figure 11, a button for executing a simulation is displayed and tapped.

[0043] Execute and display the cache flow simulation shown on screens G30 to G32 of FIG. 12. Here, perform a simulation of whether a loan can actually be repaid by inputting rent, income, down payment, etc. On screen G32 for displaying the results, re - input and re - editing are possible after re - input.

[0044] If the above content is acceptable, the buyer proceeds to apply for a loan purchase. The loan purchase application form is divided into three stages.

[0045] On screens G33 and G34 of FIG. 13, as the first stage, input name, address, workplace, phone number, etc.

[0046] On screen G35 of FIG. 13, as the second stage, input family composition, etc. On screens G36 of FIG. 13 to G37 - G39 of FIG. 14, as the third stage, the scheduled contract date, purchase price, down payment, etc. are displayed, and finally, confirm the last - entered item and tap "Send".

[0047] As shown on screen G40 of FIG. 15, a pop - up menu of "Application Accepted" is displayed. After this, the process of contract conclusion, delivery, payment, settlement, etc. follows. Then, the screen returns to the dashboard screen G41.

[0048] Explain the case when the "Want to Sell" button is tapped on screen G42 of FIG. 16. On screen G43 of FIG. 16, a "Conduct Appraisal" button is displayed, and tapping it executes the appraisal.

[0049] As shown on screen G44 of FIG. 17, select either the "Simple Appraisal" or "Detailed Appraisal" button. When "Simple Appraisal" is selected, input information such as the number of years of construction, floor area, nearest station, time to the station, etc. on screen G45 of FIG. 17, and tap "Calculate Input Purchase Price".

[0050] As shown on screens G46 and G47 of FIG. 17, a rough appraisal amount (19 million yen to 21 million yen on the screen) is displayed on the same screen as the input information.

[0051] On the other hand, when "Detailed Appraisal" is tapped, a message for logging in is displayed as shown on screen G48 in Fig. 18. Log in on screen G49 in Fig. 18.

[0052] Subsequently, on screen G50, if it has already been registered in the database (hundreds of thousands of records are registered. 90% of studio apartment properties), select the registered property.

[0053] If it is not registered in the database, enter and register the property name and address from screen G51 in Fig. 18.

[0054] In this embodiment, the case where it is registered in the database will be described. As shown on screen G52 in Fig. 19, select the registered and displayed property. Thereby, as shown on screen G53 in Fig. 19, the property details are displayed. After confirmation, proceed to the input.

[0055] On screens G54 and G55 in Fig. 19, enter room information, room number, floor plan, etc. Subsequently, enter the rental information on screen G56 in Fig. 20. On screen G57, enter management fees, etc. On screen G58, enter the remaining debt, number of years of ownership, etc.

[0056] Based on the above input information, display the provisional market price, price basis, market price, etc. as shown on screen G59 in Fig. 20. Then, the seller enters the asking price for sale from screen G59.

[0057] Enter the selling period as shown on screen G60 in Fig. 21. Subsequently, confirm the information entered so far on screen G61.

[0058] The seller requests an appraisal as shown on screen G62 in Fig. 21. Then, messages such as "Appraisal request received" and "Please wait a while until the appraisal is completed." are displayed. Then, return to the dashboard on screen G63.

[0059] On the one hand, when the assessment is completed, the seller can confirm it from the screen G64 in FIG. 22. Thus, the price changes from the provisional market price to the market price. Select the "List" or "Do not list" button from the screens G64 and G65 in FIG. 22. If "Do not list" is selected, enter the reason for not listing as shown in the screen G66 in FIG. 22. If listing, enter the desired minimum price and the desired maximum price. Then, return to the dashboard screen shown in the screen G67 in FIG. 23.

[0060] As a result, as shown in the screen G68 in FIG. 23, it will be listed in the listing list.

[0061] FIGS. 24 to 27 are sequence diagrams of member registration in the present embodiment. As shown in FIG. 24, in the present embodiment, the member registration unit 110 registers individual members and corporate members. The individual member information includes gold member R1 and platinum member R2, and the corporate member is gold member R3.

[0062] The registration of corporate members will be described with reference to FIG. 25. The member registration unit 110 determines whether it is a normal member based on the registration information from the seller terminal 10 or the buyer terminal 20 (S10). In step S10, if it is not a normal member (for example, in the case of the first time, etc.), it is registered as a normal member (S11). Thereafter, the member registration unit 110 performs the processing.

[0063] If it is determined to be a normal member in step S10, it is determined whether it is an individual member or a corporate member (S12). If it is determined to be an individual member in step S12, an individual gold member is registered (S13).

[0064] If it is determined to be a corporate member in step S12, the basic corporate information is input (S14), and the process of consenting to the anti-social check usage agreement is performed (S15). Then, it is determined whether consent is given (S16), and it is determined whether consent is given to the CIC management transfer (S18).

[0065] If consent is given, the company confirmation and anti-social check process are performed (S19), and it is determined whether the gold member status is available (S20).

[0066] If not a Gold member, set as a Black member (S21). If it is a Gold member, perform Gold member registration processing (S22).

[0067] Next, the individual Gold member registration process will be described with reference to Fig. 26. As shown in Fig. 26, the membership registration unit 110 determines whether it is a normal member as described above (S30). If it is not a normal member, register it as a normal member (in the case of the first time, etc.) (S31).

[0068] If it is not a normal member, determine whether it is an individual or corporate member (S32). In the case of a corporate member, perform corporate member Gold registration processing (S34). In the case of an individual member, have the individual basic information and questionnaire input (S33), and perform the process of having the user agree to the anti-social check usage agreement (S35).

[0069] Then, determine whether the user agrees (S36), and determine whether the user agrees to the CIC management transfer (S37).

[0070] If the user agrees, perform anti-social check processing through API connection (S38), perform eKYC check (S39), and perform anti-social check (S40).

[0071] If it is difficult to determine the anti-social check, make an individual judgment by the operation (S41). The person in charge inputs it into the terminal. Then, make a determination (S42). If it is NG, set it as a Black member (S43).

[0072] Also, if the determination is OK, register as a Gold member (S44).

[0073] Next, the Platinum member registration will be described with reference to Fig. 27. However, Fig. 27 assumes that it is a Gold member.

[0074] After the my page registration process (S50), the membership registration department 110 performs platinum membership registration processing (S51). At this time, it communicates with the financial institution system 50 to determine whether a loan can be arranged or if there are unexpected circumstances, and conducts consultation processing (S52). This is done by phone, email, etc.

[0075] In addition, when performing the aforementioned platinum membership registration, it determines whether it is a platinum member (S56), whether two years have passed since the previous platinum membership registration (S57), and whether it is the most recent data (S58), and notifies the results to the platinum membership registration process in S51.

[0076] That is, it provides unique preferential measures for excellent members. On the other hand, at the time of winning the bid, if there is a financing need (buyer), financing processing is performed (S59). However, it obtains information such as the type of funds, whether the bank review has been completed, the content of the review results, and the existence of other borrowings from financial institutions such as banks and review institutions.

[0077] That is, for platinum members, if less than two years have passed since the previous time and it is the most recent case, financing is accepted. Therefore, excellent members will always be given preferential treatment.

[0078] The overall life cycle of this embodiment will be described with reference to FIG. 28. As shown in FIG. 28, first, the seller operates the seller terminal 10 to access the property transaction support server 101 of the property transaction site 100 and registers the listing information of the studio apartment (d10). This listing information consists of the property address, property photos, age, facilities, asking price, etc.

[0079] Then, the person in charge of the property transaction site 100 appraises this property information (selling property condition information) (appraisal amount, etc.) on the screen of the site-side terminal 200 (d12). Then, the person in charge of the property transaction site 100 provides this property information to the auction site on behalf of the seller (d14), signs a contract after winning the bid (d16), and settles the payment (d18). This is the process.

[0080] Note that the property information includes, for example, price, category (single-family house, condominium, studio, land, condominium for building sale, apartment for building sale, building, etc.), area, floor plan, age of construction, region, number of floors, direction, frontage, type of adjacent road, width of adjacent road, terrain, topography, public status of the property (unpublished property that can only be publicly disclosed in a limited manner, publicly disclosed property that can be publicly disclosed without limitation), etc., but is not limited thereto.

[0081] Using FIG. 29, the details of the specific transaction flow (transaction life cycle) will be described. This process is performed by the auction processing unit 120 of the property transaction support server 101 of the property transaction site 100.

[0082] Listing preparation (d10) performs pre-listing processing. This pre-listing processing includes pre-listing inoperability (d22), pre-listing withdrawal (d24) where the seller withdraws the listing before listing, pre-listing withdrawal (d26) where the site side withdraws the listing before listing, etc. (such as anti-social organizations, etc.).

[0083] Auction (d14) is a case where the listing becomes valid through pre-listing processing, and there are situations such as listing suspension (d32) where the listing becomes unsalable after listing and before the expiration of the listing period, and listing expiration (d34) where the listing period expires and the listing becomes unsalable after listing.

[0084] And before the listing is completed, but the contract is almost finalized in the auction and the listing ends (d40), and the transaction is completed (d50).

[0085] In this embodiment, as shown in FIG. 30, relisting of the same property is possible (relisting processing unit 130). For example, if seller A lists property A (d40) and even if the listing is withdrawn, but buyer A purchases the property, then that property A is managed as transaction B (d41). That is, the buyer of the property information is associated and registered as B.

[0086] The preparation for listing will be specifically described with reference to Fig. 31. As shown in Fig. 31, the seller accesses this website and inputs the room information of the studio apartment (address, photos, price, floor plan, facilities, seller information, etc.) (d52).

[0087] The relisting processing unit 130 determines whether it is possible to present a tentative market price based on this room information (address, photos, price, floor plan, facilities, seller information, etc.) (d54). If it is not possible to present a tentative market price, listing is not allowed. This may also be done by the person in charge by viewing the site-side terminal 200.

[0088] If it is determined that a tentative market price can be presented, the tentative market price is presented (sent) to the seller terminal 10 as tentative property transaction information (including the property number) (d56). When the tentative market price is presented, the seller is made to input the selling conditions (d57), and it is determined whether this seller is a gold member (d58). If not a gold member, gold member control processing is performed (d59). This may also be done by the person in charge by viewing the site-side terminal 200.

[0089] Also, in the case of a gold member, a listing appraisal is performed (d60).

[0090] The description of the listing appraisal will be supplemented with reference to Figs. 32 and 33 (however, it will be described in the case of a lease contract).

[0091] The person in charge of the site transmits the room information on the screen (address, photos, price, floor plan, facilities, seller information, etc.) to an external registration information providing service site (for example, it may be the judicial scrivener's personal computer 40) to obtain registration information (d61, d62).

[0092] Next, this registration information is uploaded (d63), a brokerage contract is created, and the seller is made to sign it via the electronic contract service site (d64, d65, d66). Also, the seller operates the seller terminal 10 to upload the lease contract, etc. from the registration information providing service site, and the person in charge of the registration information providing service site operates the site-side terminal 200 to obtain the lease contract, etc. (d67, d68).

[0093] At this time, if there is any deficiency, the person in charge shall take separate actions to obtain a lease contract or the like from outside and upload it (d69, d70, d71). Then, various appraisals are performed based on this lease contract, and the results are registered (d72, d73).

[0094] Then, it is determined whether handling is impossible (d74). If it is impossible, it is treated as an additional handling, and if it needs to be redone, it is cancelled (d76, d77).

[0095] On the other hand, if there is no problem, in the case of sales, the price is presented to the seller (d79), and the seller's intention to list is confirmed (d80). If the seller decides to list, the seller performs the input process for the listing preparation price (d81), and the site side conducts an agency contract, confirms the transaction description, and performs the listing operation to start an auction (d82~d85).

[0096] In addition, in the transaction, the server creates the property registration screen, and the information input on this property registration screen (referred to as property registration information) is registered in the storage unit. The property registration screen consists of the property type (for example, condominium), property name, size, presence or absence of a deposit, etc.

[0097] Also, in order to register property photos, property photo information (including photos, identification codes of owner information, date, year, month, day, hour, minute, and second, etc.) is registered. On the other hand, the buyer logs in to the site using an account and receives a screen (not shown) for inputting desired requirements.

[0098] For example, information about the desired property (name, phone number, location of the desired property, size, brightness, price range, etc.) is input and sent to the site. Then, every time property information is stored, the site searches for the registered property information that meets this desired property information and sends the searched property information to the buyer.

[0099] The site can also communicate with the seller terminal, the buyer terminal, and the judicial scrivener terminal via chat. For example, from the registration of the initial property information, some information is concealed and publicly disclosed (displayed), and chat (dialogue) is directly conducted with the consent of the buyer in response to inquiries from the registered buyers.

[0100] After several dialogues, if the buyer applies to the server's reception means for property guidance, after obtaining the seller's consent, the possibility of a deal is judged. If it is high, other information (which may include personal information) is added and the property information (information including the seller and the buyer) is sold.

[0101] Although each embodiment has been described in detail, it is not limited to a specific embodiment, and various modifications and changes are possible within the scope described in the claims. Also, it is possible to combine all or a plurality of the constituent elements of the above-described embodiments.
