Abstract

The present invention relates to a system and method of bargaining for a real estate transaction that a buyer and seller can directly bargain with each other over the amount and terms and conditions of a real estate transaction in real time. When one terminal approves a transaction, the transaction is concluded while the transaction is terminated so that all terminals cannot make inputs and the determined amount and terms and conditions of the transaction are immediately notified to a real estate broker terminal so that a buyer and a seller can negotiate directly with terminals, thereby making the buyer and seller easy to write a contract.

Description

The bargaining system and method of real estate transaction

This outbreak relates to a bargaining system and method for real estate transactions. Specifically, buyers and sellers can directly negotiate the transaction amount and conditions of real estate transactions through the Internet and a dedicated application in real time through a terminal. When the transaction is approved, the transaction is concluded, and at the same time, all terminals are unable to enter the transaction. As soon as the transaction is terminated, the transaction amount and the transaction conditions determined by the real estate broker terminal are notified, making it easy for the seller and the seller to negotiate directly through their terminals. It relates to a bargaining system and method for real estate transactions that can be made up to.

The use of wireless terminals such as terminals has already become common, and various additional services using wireless terminals in addition to basic functions are being performed. Among these additional services, a new possible field is the service that buyers and sellers can negotiate through the Internet and applications in real estate transactions.

Until now, real estate transactions have been handled only in limited real estate offices where the seller and the buyer delegated all transactions to the real estate broker to search for limited real estate properties held by the real estate broker with real estate brokers, or where the buyer must visit the real estate to find the real estate. In order to obtain information on real estate for sale using the Internet and wireless terminals, Internet Naver, Jikbang App, and Dabang App have been used recently.

The limitation of these Jikbang apps and Dabang apps is that there is only the function of providing information on the desired real estate to be traded by the seller, and the next step, a system for negotiating the transaction amount and trading conditions of the seller and buyer, has not yet been provided.

Therefore, in the present invention, when the information on the desired real estate is registered with the seller terminal on the server, the buyer sees this and puts it in the shopping cart for the real estate as a transaction wish indication on the terminal, and immediately sends a notification to the seller terminal and the seller terminal shopping cart. It is stored and the seller changes the transaction amount and conditions displayed at the time of real estate registration in order to close the transaction and enters the new transaction amount and conditions, and it is sent back to the buyer terminal, and the buyer reports the newly proposed transaction amount and conditions transmitted by the seller terminal. , If the buyer enters the new transaction amount and conditions desired by the buyer into the buyer's terminal, the bargaining process is immediately transmitted to the seller's terminal.

If the transaction is approved by either the buyer's terminal or the seller's terminal, the transaction is concluded and the transaction is concluded.At the same time, the transaction approval result is automatically notified to the real estate broker terminal with the details approved by the seller and the buyer, and the transaction is approved within the specified period. When registering real estate to be sold on the server with the seller terminal, a dedicated real estate brokerage office can be selectively designated.If the real estate brokerage office is not designated, the transaction result will be reported when the real estate transaction is approved with the seller terminal and the buyer terminal. It relates to a bargaining system and method for real estate transactions, characterized in that direct transactions in which sellers and buyers can directly make contracts are possible without notifying the real estate broker terminal.

Therefore, until now, only specific real estate brokers deal with limited sales of real estate requested by the seller, and there is a limited method of publicly notifying the real estate to those who wish to purchase the real estate, like a court real estate auction. If the property is not designated as a dedicated property and the property is exposed to other real estate brokers by registering the property in several real estate agency offices, the transaction may be missed. Therefore, the exact address of the property is not exposed, and only the surrounding area is exposed. The reality is that false sales are also registered to attract buyers who abused this. In addition, real estate brokers have complained that the seller and buyer were not always able to trade at a fair amount after the transaction due to transactions by limited areas and limited real estate brokers, such as prioritizing transactions of real estate with high brokerage fees in order to increase income. In addition, even though the real estate transaction has ended, real estate brokers who are not aware of the real estate transaction continue to promote the real estate.

In order to solve the problems of real estate transactions described above, the present invention allows the buyer to search real estate registered on the server with a terminal in the country, and if he wishes to purchase, the buyer can directly inform the seller of his intention to trade through the terminal. If you put it in the shopping cart, it is immediately sent to the seller to negotiate the transaction amount and transaction conditions, and if you approve the transaction on either terminal of the proposed transaction amount and transaction conditions, the transaction is immediately concluded and all the The terminal can no longer input into the terminal with a message notifying that the transaction has ended, and the transaction is terminated.

In addition, the transaction amount, transaction conditions, and information of the seller and buyer are notified to the real estate broker's terminal, so that a contract can be prepared.

In addition, if you visit the site to check the transaction property directly and take a picture of the street name address plate attached to the building with the terminal camera, without entering the address on the terminal's letter board, in the case of buildings and houses (hereinafter referred to as "building"). By recognizing the road name address of the building as a text, such as the name and resident registration number, the same address is searched and searched for, and the function shows real estate information for the building on the screen, and the real estate for the building found by recognizing the address by voice. It provides a real estate transaction bargaining system and method that allows you to selectively search for the relevant property on the site by providing three methods including the function of showing information and the function of searching for the relevant building by entering the address on the letter board. have.

In order to conveniently display the area of the room size calculated by the width and length by linking the terminal and the server, the room size is paralleled to ㎡, and the size of a single bed for one person is 2㎡ (2㎡ = 1m wide * vertical). By standardizing the size image to 2m), the server can provide a service that displays the room size with the number of single beds automatically calculated.

In order to achieve the above-described purpose, the real estate transaction bargaining system registers the real estate desired for real estate transaction, stores the real estate information, and processes the specific real estate registered on the server as a buyer terminal in the shopping cart. When saved, the counterpart terminal that registered the real estate is notified with a notification message and notification sound.

When the counterparty enters a new transaction amount and transaction conditions to close the transaction for the property notified by a notification message and a notification sound, the transaction is automatically transferred to the buyer's terminal in the shopping cart, and the buyer is sent a new transaction sent by the seller's terminal. A terminal capable of continuing the bargaining process of repeating the transfer to the buyer terminal immediately after viewing the presented transaction amount and conditions and entering the new transaction amount and conditions desired by the buyer into the buyer terminal.

If the property is a building or house, that is, a building, after visiting the site, without entering the address directly with a terminal keyboard such as a mobile phone, take a picture of the road name address plate attached to the building with a mobile phone camera and text the text in the picture. Recognized as the real estate information for the relevant building, you can conveniently check the real estate on the site, and even after checking the real estate on the site and a terminal that can search the real estate information of the relevant building stored on the server by voice By continuing to negotiate to propose new transaction amounts and conditions, the transaction is concluded immediately if either the seller's terminal or the buyer's terminal approves the transaction amount and the transaction conditions proposed by the other party. It is composed of a terminal using a communication network notified to a real estate broker terminal.

Real-time real estate information, notification, search, and transaction approval are automatically displayed on the terminal screen.

A display unit that automatically calculates and displays the number of single beds of the size of a single bed, which is 2㎡ (2㎡ = 1m wide*2m long), and the image is standardized, and data storage that stores all real estate information and transaction information. It is composed of a processing unit that processes input information of the terminal, such as notifications and shopping cart additions, and can be added to the shopping cart only by depositing the designated amount.

It relates to a bargaining system and method for real estate transactions, characterized in that the computer program for performing the method according to the above-described embodiment can be stored in a recording medium recorded in a computer program according to an embodiment of the present invention.

By using the real estate transaction bargaining system and method, it is possible to prevent the real estate transaction from becoming complicated and misunderstanding due to the involvement of many real estate brokers in the formerly, sellers, buyers, and many real estate brokerage offices. Real estate brokers prioritize real estate with high brokerage fees, and do not actively trade real estate with low brokerage fees, or sell the real estate for sale only at specific real estate brokerages, so that buyers and sellers who wish to trade will operate the real estate. With the present invention that the property for sale cannot be known without a good meeting, the exact real estate information marked with the address for the property is disclosed to anyone like a court auction property, so that the seller and the buyer can directly trade the property to quickly close the property. With the effect of helping a lot in transparent transactions at an appropriate price, it is possible to prevent the fair transaction price for real estate sales and the demand for unfair brokerage fees from real estate brokers.

In addition, the present invention can selectively designate a dedicated real estate brokerage office when registering real estate to be sold on the server with the seller terminal. If a real estate brokerage office is not designated, the seller and buyer will be informed when the real estate transaction is approved by the seller terminal and the buyer terminal. During bargaining, personal information such as personal information and phone numbers of the seller and buyer, which were not provided, are provided, so without notifying the transaction result to the real estate broker terminal, it is possible to conduct a direct transaction in which the seller and the buyer can directly make a contract.

The use of the present invention has the advantage of being able to negotiate as if playing games through a terminal rather than face-to-face with the adjustment of the transaction amount for the transaction only through a real estate agent.

Also, if the property is a building or house, that is, a building, you can take a picture of the road name address plate attached to the building with a mobile phone camera without entering the address directly on the mobile phone terminal. By recognizing the building address of the building, you can conveniently check the real estate on site by searching the registration information for the building, and a function to search the real estate information of the building stored on the server by voice is provided.

In particular, for young people, room size indications such as studios cannot be easily understood by reminiscent of the current pyeong (3.3㎡) or ㎡ displayed area, so if the items are small in daily life, a single server can be used as if comparing with a coin or cigarette pack next to it. By calculating the bed size as 2㎡ (width: 1m, length: 2m, size = 2㎡), the room size is uniquely displayed as a standardized image paper of the bed size instead of a cigarette pack so that anyone can easily understand the room size. I can help.

Furthermore, until now, in the case of renewal of charter or monthly rent for apartments, studios, officetels, etc. where you currently live, you usually do not face each other, but before the contract expires, both sides have discussed the extension over the phone. When there is no record of the call, there is room for contention, and it is true that the relationship between the landlord and the tenant is a relationship between the tenant and the tenant, so it is not easy for the tenant to negotiate sufficiently through voice due to lack of experience. By omitting the visiting step, the owner and the tenant of the real estate negotiate directly through the app of the present invention, such as chat without face-to-face, without going through the real estate brokerage office to obtain a satisfactory result and automatically save the record at the same time There is a convenience that can be used extensively in relation to real estate transactions, such as being able to fundamentally block the room for contention later.

Another feature of the present invention is that not only one seller terminal and one buyer terminal deal with a bargaining transaction for one real estate, but the seller terminal that first registered the real estate on the server is used by a number of real estate brokers for fast transaction. Real estate brokerage transactions are possible separately from the first seller who registered the real estate on the server by entrusting the transaction to the seller terminal, and one seller terminal among a number of delegated seller terminals can bargain with a number of buyer terminals.

In fact, at least one seller terminal and one buyer terminal can bargain for one registered real estate, and as many as 50, many buyers' terminals negotiating with the 10s, 20s, and 30s that are commissioned to sell. 100 units, 200 units... More one real estate can be bargained at the same time, and when one of the hundreds of terminals sees the transaction price and transaction conditions proposed by the other terminal and clicks "transaction approval", the transaction is established at the same time. As a result, all the sellers' terminals and buyers' terminals that were in progress stop bargaining for the real estate transaction, and immediately notify the end of the transaction by the server, "The deal with other buyers is approved and the bargaining ends" or "The deal with other sellers is approved and the bargaining is made. At the same time as the notification message is sent, bargaining and information input for the real estate is stopped, and the transaction is terminated, allowing you to trade the real estate quickly and with the right amount and conditions.

In addition, the server 100 registers real estate information desired for transaction from the seller terminal 220 and the buyer terminal 230, and the users and terminals of the seller terminal 220, the buyer terminal 230, and the real estate broker terminal 210 It registers and stores information, controls and manages computer programs, and provides necessary information in real time.

For example, if a buyer A wants to buy a specific real estate among the real estate information provided from the server 100, when he clicks Add to Cart (B900) with the buyer terminal, the real estate is the buyer terminal 230 and the seller terminal 220 ) It is displayed in the shopping cart (B910), and at the same time, the seller B who registered the property in the shopping cart is notified with a notification message and notification sound that it has been stored in the shopping cart (B910) of the seller's terminal 220, and seller B makes the transaction. In order to do so, when a new desired transaction amount and transaction conditions are entered into the seller's terminal 220, the new transaction amount and transaction conditions are automatically notified to the buyer A's terminal 230, and the buyer A After looking at the transaction conditions, the buyer A and the seller B's terminals repeatedly negotiated to transmit (suggest) the new transaction desired amount and transaction conditions to the seller B's terminal 220, and then the buyer A and the seller B's terminals determine the transaction amount and transaction conditions proposed by the other party. If you click OK, the transaction is concluded, and the transaction approval details are immediately notified to the real estate broker terminal 210 so that the real estate brokerage office can implement the contract business.

In addition, when the server 100 visits the site to check the real estate and takes a picture of the road name address plate attached to the building with a mobile phone camera to check the corresponding building, the server 100 immediately recognizes the address and shows the real estate information about the building (310 ), you can search by speaking the address by voice (330), and by entering the address by using the mobile phone (320), you can search for real estate information at the site and view it with a terminal, and all transaction information is automatically saved. Process.

The seller terminal 220 inputs real estate information to be sold to the server 100 wishing to sell the real estate, and when notified that the real estate to be sold is stored in the shopping cart from the buyer terminal 230, it presents other transaction amounts and transaction conditions. It is possible to negotiate, and when the transaction is successful, it is connected to the server 100 and the communication unit 150 to a terminal capable of transmitting the transaction result to the real estate broker terminal 210 to transmit and receive various information of the server.

The buyer terminal 230 is a terminal of a buyer who wishes to purchase the real estate. If there is a specific real estate to be purchased among the real estate provided from the server 100, if it is stored in the shopping cart B910, it is immediately transmitted to the seller terminal 220 and the new transaction price and The transaction conditions may be received from the seller terminal 220, and the bargaining process of changing the transaction price and transaction conditions of the received real estate to be sold to the seller terminal 220 may be continued.

In addition, when visiting the site to check the real estate during a bargaining, by taking a picture of the road name address plate attached to the building with a mobile phone terminal, the address of the building at the corresponding address is recognized, and the address is sent from the server 100 to the character plate of the mobile phone terminal. You can receive and view real estate information without entering it, and even after confirming the site of the real estate, the other party, whether the buyer terminal 230 or the seller terminal 220, meets the conditions presented to both parties by continuously negotiating the transaction amount and transaction conditions with the seller. As soon as the proposed condition is approved, the transaction is concluded and terminated immediately, and it is connected to the server 100 and the communication unit 150 as a terminal capable of transmitting the transaction result to the real estate broker terminal 210, so that information of the server can be used in various ways.

When the buyer terminal 230 and the seller terminal 220 approve the transaction price and transaction conditions presented by the other party, the transaction is concluded and the transaction is terminated, and a contract is made based on the reported transaction result information. It can be created, and when registering the real estate to be sold on the server with the seller terminal, it is possible to selectively designate a dedicated real estate brokerage office.If a real estate brokerage office is not designated, the transaction result will be displayed when the real estate transaction is approved by the seller terminal and the buyer terminal. Without notifying the broker's terminal, the seller and the buyer can make direct contracts.

The letter plate input unit 320 is an input system that can input the trader's personal information, real estate information, and bargaining information to the server through the letter plate of the terminal.

The camera input unit 310 is the seller terminal 220, the buyer terminal 230, the real estate terminal 210, the server recognizes the image of the road name address plate attached to the building with a mobile phone as letters, and real estate information of the server. It is an input system that provides a function to search without entering an address on a letter board, and to take pictures and videos related to real estate and store them in the server 100

The voice input unit 330 recognizes the information of the server 100 as a text when speaking with a voice without entering a text on the dial of the mobile phone among the seller terminal 220, the buyer terminal 230, and the real estate terminal 210. It is an input system that searches and displays.

The data storage unit 410 stores personal information and terminal information of buyers, sellers, and real estate brokers related to real estate transactions, real estate information about real estate, information generated during a bargaining process, and various information related to real estate transactions in the server, and (210, 220, 230), the server 100, and other terminals that wish to make one or more transactions store data and programs necessary to operate, and also various user interfaces (UI), graphic user interfaces (Graphic User).

2 is a flowchart illustrating a real estate transaction bargaining system and method according to an embodiment of the present invention.

Referring to FIG. 2, the server 100 may transmit information including a transaction amount and transaction conditions for real estate to the seller terminal 220 wishing to make a real estate transaction, and register and store it in the server (S610). The real estate information includes the registration date, building name, photo, number of floors, location address, completion date, floor plan, area, size, etc. for the desired property, air conditioner, bed, washing machine, elevator, microwave oven, desk, It may include registering information on real estate brokerage fees, such as chairs, the desired amount of transaction, transaction conditions, rental deposit, rental fee, etc. on the server.

In addition, the server 100 searches for the real estate stored in the server 100 with the buyer terminal 230 to buy the real estate, and then, if there is a real estate of interest or a real estate that wants to bargain for a transaction, add the real estate to the shopping cart ( When B900) is clicked, information indicating that the buyer has put it in the shopping cart B910 is automatically notified to the seller terminal that registered the real estate (S620).

That is, putting it in the shopping cart with the buyer's terminal 230 can be regarded as a step of expressing an intention through a computer that a person is interested in the property, and that a bargaining begins when the transaction price or transaction conditions are met.

According to an embodiment of the present invention, the server 100 is a step of receiving a notification from the buyer terminal 230 that the seller terminal 220 has put the desired real estate registered in the server in the shopping cart B910 (S630). ).

In other words, the buyer terminal 230 clicks the add cart (B900), and at the same time, the seller terminal 220 through the server 100 displays a notification 610 along with a notification sound "Thing ~ Dong" on the screen. The time that the buyer terminal 230 put in the shopping cart is displayed along with the notification text "

The server 100 checks that the desired real estate is contained in the shopping cart in the seller terminal 220, and informs the buyer terminal 230 by changing the transaction amount and transaction conditions currently registered in the server 100 in order to close the transaction. The real estate transaction can be bargained in a way that can be done (S640)

That is, the seller may transmit the changed transaction amount and transaction conditions to the seller terminal 220 to the buyer terminal 230 with the transaction amount and conditions more favorable to the buyer in order to close the transaction. In addition, the seller has to enter the buyer terminal 230 if the transaction amount and conditions do not change.

In addition, the server 100 is a road name address attached to the building by terminal cameras of terminals 210, 220, 230 to facilitate and conveniently search for the desired real estate when the buyer visits the site to check the actual real estate. Three methods (S650) including a method of searching by photographing a plate (S651), a method of searching by entering an address with a terminal font (S652), and a method of searching for an address using terminal voice recognition (S653) are selectively selected on one screen. It can be used to accurately search the relevant property on site.

In more detail, when the real estate is a building or a building, when the road name address plate attached to the building is photographed with a terminal camera, the server 100 immediately recognizes the address of the road name address plate as text and searches for the building at the corresponding address. With a technology that displays on the screen afterwards, you can conveniently search for real estate on site (S651), and in the case of land without buildings, you can search by entering the lot number with the terminal font (S652), or by voice (S653). ), three search methods (S650) can be selectively used on one screen, enabling a service to search for real estate without manually entering the terminal screen in winter or hot summer.

The server 100 checks the price and transaction conditions of the desired property sent from the seller terminal 220 to the buyer terminal 230, if the buyer who has confirmed the on-site request continues to negotiate the transaction, and then the price and transaction the buyer wants. By inputting the condition, it is transmitted to the counterparty, the seller terminal 220, and the bargaining can be continued (S660). The seller terminal 220 also checks the price and transaction conditions of the desired transaction property transmitted from the buyer terminal 230 from the server 100, and then transmits the new transaction price and transaction conditions to the buyer terminal 230. The process can be continued (S660)

In addition, when the buyer terminal 230 does not want to proceed with the transaction any more, the server 100 clicks the'interrupt transaction' 620 displayed on the screen, and at the same time, the buyer terminal 230 sends a message to the counterparty, the seller terminal 220, "the buyer stops the transaction. "I did" message and the transaction interruption time are displayed, and the transaction negotiation ends.

In addition, if the seller terminal 220 no longer wants to proceed with the transaction with the corresponding buyer, if he clicks'interrupt transaction' (620) displayed on the screen, at the same time, the buyer terminal 230, the counterparty, "Seller stopped the transaction". Message and the transaction interruption time are displayed, and the transaction negotiation of the two terminals ends.

According to an embodiment of the present invention, the server 100 is the buyer terminal 230 and the seller terminal 220 continuing to negotiate while continuously changing the price and transaction conditions of the real estate, and then the buyer terminal 230 or the seller terminal ( 220) If you click "transaction approval" 630 on the terminal screen after viewing the price and transaction conditions presented and transmitted by the other party, the real estate transaction is concluded and the transaction is terminated at the same time, and the server 100 automatically confirms the transaction. The details are notified to the real estate brokerage terminal 210, and a contract may be created with the notified transaction approval details (S670), or when registering the sold real estate on the server with the seller terminal, a dedicated real estate brokerage office may be selectively designated.

In addition, if a dedicated real estate brokerage office is not designated, if the real estate transaction is approved with the seller's terminal and the buyer's terminal, the transaction result is not notified to the real estate broker's terminal, and a direct transaction where the seller and the buyer can directly make a contract is possible.

The storage unit 410 of the server 100 stores a deposit sent from the buyer terminal 230 and the seller terminal 220 in order to guarantee a transaction. For example, the contract is not completed with the real estate terminal 210 notified by the other party within the specified period for a deposit stored in cash or guarantee insurance policy for 5% of the expected transaction amount, and the deposit is remitted to the other party as a penalty. do.

According to an embodiment of the present invention, in terms of transaction conditions with the terminals 220 and 230, the purchase and sale price, deposit, monthly rent, management fee, etc., and cleaning, washing machine, refrigerator, microwave oven, etc. Can be displayed, and the terms of the transaction specifying the contract period, interim payment, balance payment date, penalty, etc. can be included.

In addition, both the buyer and the seller can designate a reply deadline with the terminal, and if the transaction is not terminated because the real estate for sale is registered, the transaction conditions can be re-presented after the reply period has elapsed.
