Description

Apparatus for an online platform that provides real estate information {apparatus for online platform that provides real estate information}

The present invention relates to a method and device for operating a reverse auction service for real estate for sale. In detail, it relates to a service that recommends to the user an appropriate real estate listing among the proposed real estate listings, when a user enters conditions for a real estate listing for which he or she wishes to bid, and brokers propose appropriate real estate listings.

In general, reverse auctions, unlike regular auctions, are consumer-oriented commerce that allows consumers to purchase goods at the lowest price by competing with suppliers. In particular, in real estate transactions, reverse auctions not only save buyers (or consumers) the hassle of visiting multiple real estate agents to compare prices or find good properties, but also provide the fun of bargaining when prices fall.

In general, reverse auctions are widely developed only in Internet shopping malls. Anyone who wants to use a reverse auction must first visit a reverse auction website on the Internet, look at product information, and decide on a product to purchase. Then, they go to the bidding bulletin board and register the product model name, quantity, and their email address, and the reverse auction begins from then on. He visits the bulletin board from time to time to check the prices offered by companies, and after the auction closes, he checks the lowest winning bid via his email and makes an electronic payment or remittance.
