Pre-sale of a house refers to a transaction in which the buyer pays a down payment and owns an existing house in the future. In fact, it is only a futures contract, and it and the finished house have become two forms of housing sales in the market. What is the pre-sale system of commercial housing?

① Pre-sale houses must be built into houses, not social welfare houses or social relief houses, nor non-socialized and commercialized houses such as self-built fund-raising houses within units. Therefore, this kind of housing has the characteristics of socialization and commercialization.

② The pre-sold houses are in a specific state, that is, they must be under construction and under normal construction, but there are no unfinished commercial houses. It is not a project that has not yet started, nor an existing house that has been completed, nor is it a semi-finished project that has stopped working. The completion time is determined.

③ Pre-sale houses exist objectively and are under normal construction. Commercial housing does not exist before completion. Therefore, as an unfinished delivery, it is not a real pre-sale, but a feature of pre-sale.

④ The main body of the pre-seller is the commercial housing developer, who has the qualification of pre-selling commercial housing, that is, the legal specific enterprise. Any citizen who wants to buy a pre-sale house can become the buyer of the pre-sale house.
