Description

Technical Field

[0001] The present invention belongs to the technical field of real estate transactions, and in particular relates to an online house transaction method, system and program product for realizing balanced transactions. Background Art

[0002] At present, the existing housing transactions in the real estate market mostly adopt the transaction mode of broker matchmaking. This real estate transaction method has certain disadvantages, such as: 1. Information opacity and asymmetry. Under normal circumstances, buyers and sellers are relatively passive compared to the broker's knowledge. Most buyers and sellers understand the transaction cycle and price information of the market housing through the broker's oral communication, but there are considerable limitations. It is impossible to obtain comprehensive information on the price and selling / buying intention of the same type of housing, and its authenticity cannot be verified. 2. Buyers and sellers cannot obtain more transaction objects. The existing real estate transactions are more often communicated through the broker's retelling in a "back-to-back" or "one-to-one" manner, and it is impossible to achieve "one-to-many" or "many-to-many" "collective" docking. In the same time period, the transaction parties cannot obtain more real intention demand and intended price information, which may cause misjudgment of transaction decisions. 3. It is easy to mislead transactions. That is, it is easy to artificially "raise prices" or "press prices", provide misleading and biased information, and mislead the decision of buyers / sellers. The existence of these drawbacks leads to low transaction efficiency for buyers and sellers in traditional real estate transactions, and may even easily lead to situations where the interests of both parties are harmed.

[0047] Embodiment 1:

[0048] This embodiment provides an online house transaction method for achieving balanced transactions, which can be applied to corresponding real estate transaction platforms, such as Figure 1 As shown, the method comprises the following steps:

[0049] S1. Obtain the listing information of the property to be traded published by the seller.

[0050] In specific implementation, the platform first obtains the housing information of the property to be traded released by the seller, and the housing information includes the city information, regional information, project information, orientation information, apartment type information, floor information and housing area information corresponding to the property to be traded.

[0051] S2. Determine the reference price information of the real estate to be traded based on the house source information of the real estate to be traded, send the reference price information to the seller, and receive the listing price fed back by the seller based on the reference price information.

[0052] In specific implementation, after obtaining the house source information of the property to be traded, the platform can determine the reference price information of the property to be traded based on the house source information of the property to be traded, and the reference price information includes the appraisal price, the latest transaction price of similar properties, the reference price of similar properties that have been traded, and the reference price of similar properties that are being sold. Among them:

[0053] The latest transaction price of similar properties: In the same city, area, project, orientation and apartment type, you can select the transaction price of one property within the set area range that was recently sold as the latest transaction price of similar properties. The set area range can be set to [0.9 times the area of ​​the property to be traded, 1.1 times the area of ​​the property to be traded].

[0054] Reference price for similar properties that have been sold: In the same city, area, project, orientation and apartment type, you can select the maximum or average transaction price of the 10 most recently sold properties within the set area range as the reference price for similar properties that have been sold. The set area range can be set to [0.9 times the area of ​​the property to be traded, 1.1 times the area of ​​the property to be traded].

[0055] Reference price for similar properties for sale: In the same city, region, project, orientation and apartment type, you can select the maximum or average listing price of the 10 properties recently listed for sale within the set area range as the reference price for similar properties for sale. The set area range can be set to [0.9 times the area of ​​the property to be traded, 1.1 times the area of ​​the property to be traded].

[0056] Appraisal price: It is estimated based on the city information, area information, project information, orientation information, apartment type information, floor information and area information corresponding to the property to be traded, as well as the recent transaction price of similar properties, the reference price of similar properties that have been sold and the reference price of similar properties that are currently for sale.

[0057] After determining the reference price information, the platform will send the reference price information to the seller for reference in setting the listing price, and receive the listing price feedback from the seller based on the reference price information.

[0058] S3. Determine whether the listing price is a valid listing price based on the reference price information, and when the listing price is determined to be a valid listing price, push the property information and reference price information of the property to be traded to each buyer.

[0059] In specific implementation, the platform first determines whether the listing price is a valid listing price based on the reference price information. When 0.5 times the appraisal price ≤ listing price ≤ 1.5 times the appraisal price, it determines whether the listing price is a valid listing price. After determining that the listing price is a valid listing price, the seller needs to pay a deposit to the platform to guarantee the listing price set by himself, proving that the seller's listing price is real and valid and cannot be regretted. Then, the platform can push the house information and reference price information of the property to be traded to each buyer for reference and bidding.

[0060] S4. Obtain the buyer's bid of the corresponding buyer at the current moment, as well as the bidding price before the current moment, and determine whether the buyer's bid is a valid bid based on the listing price and the bidding price.

[0061] In specific implementation, the buyer side also needs to pay a deposit before bidding to guarantee its bid and prove that the buyer side's bid is real and valid and cannot be regretted. At the beginning of a round of bidding, the platform will take the first bid received from the corresponding buyer side as the initial bid, and then determine whether the initial bid is a valid bid based on the listing price. If the initial bid is determined to be a valid bid, the initial bid will be used as the initial bidding price of this round of bidding. Then, when conducting subsequent bidding, the platform obtains the buyer's bid of the corresponding buyer side at the current moment, determines the bidding price before the current moment, and then determines whether the buyer's bid is a valid bid based on the listing price and the bidding price, that is, when 0.5 times the listing price ≤ buyer's bid ≤ 1.5 times the listing price, and the buyer's bid ≥ bidding price + n times the set price increase, n is a positive integer greater than or equal to 1, the buyer's bid is determined to be a valid bid.

[0062] On the other hand, if the platform determines that the current bid of the corresponding buyer is greater than or equal to the listing price, the transaction is automatically determined to be completed, and then the current bid of the corresponding buyer is used as the final bidding price, and the transaction completion information is generated according to the final bidding price, and the transaction completion information is sent to the seller and the buyer corresponding to the final bidding price. Otherwise, this round of bidding will continue.

[0063] S5. When it is determined that the buyer's bid of the corresponding buyer at the current moment is a valid bid, and no new buyer's bid is obtained within the set bidding interval after the current moment, the buyer's bid of the buyer is used as the final bidding price, and the final bidding price is sent to the seller.

[0064] In specific implementation, when the platform determines that the buyer's bid of the corresponding buyer side at the current moment is a valid bid, and no new buyer's bid from other buyers is obtained within the set bidding interval after the current moment, the buyer's bid of the buyer side will be used as the final bidding price of this round of bidding, and then the final bidding price of this round of bidding will be sent to the seller side.

[0065] S6. When receiving bid confirmation information fed back from the seller within the set effective transaction period after sending the final bidding price to the seller, it is determined that the transaction is completed, and transaction completion information is generated according to the final bidding price.

[0066] In specific implementation, if the platform receives bid confirmation information from the seller within the set effective transaction period after sending the final bidding price to the seller, it means that the seller accepts the final bidding price of this round of bidding. The platform then determines that the transaction is completed and generates transaction completion information based on the final bidding price.

[0067] If the platform receives a bid rejection message from the seller within the set effective transaction period after sending the final bid price to the seller, it means that the seller rejects the final bid price of this round of bidding. At this time, the platform determines that this round of bidding is invalid, and then pushes the property information and reference price information of the property to be traded to each buyer for the next round of bidding, and receives the buyer's bid from each buyer in the next round of bidding. The buyer's bid from the corresponding buyer received first in the next round of bidding is used as the initial bid. The initial bid is determined to be a valid bid based on the listing price. When the initial bid is determined to be a valid bid, the initial bid is used as the initial bid price for the next round of bidding, and the next round of bidding continues.

[0068] If the platform does not receive any bid confirmation information or bid rejection information from the seller within the set effective transaction period after sending the final bidding price to the seller, the platform will also determine that this round of bidding is invalid, and then push the property information and reference price information of the property to be traded to each buyer for the next round of bidding, and receive bids from each buyer in the next round of bidding. The first bid received from the corresponding buyer in the next round of bidding will be used as the initial bid. The initial bid will be determined whether it is a valid bid based on the listing price. When the initial bid is determined to be a valid bid, the initial bid will be used as the initial bidding price for the next round of bidding, and the next round of bidding will continue.

[0069] S7. Send the transaction completion information to the seller and the buyer corresponding to the final bidding price.

[0070] During specific implementation, after the platform determines that the transaction is completed and generates transaction completion information based on the final bidding price, it will send the transaction completion information to the seller and the buyer corresponding to the final bidding price to achieve subsequent transaction docking between the buyer and the seller.

[0071] The method of this embodiment can realize the transparent push and intelligent management of real estate transaction information, break the information asymmetry phenomenon, and realize balanced transactions through a collective bidding transaction model, providing a transparent, fast and efficient online transaction channel for buyers and sellers of existing houses, so that buyers and sellers can complete real estate transactions without meeting in person.
