① The subject matter of the transaction is uncertain. Because the house has not been completely built and the construction period is relatively long, there are indeed many uncertainties in the transaction target. The risk of buying this type of house is indeed much greater than that of an existing house. For example, after the developer receives the house payment in advance, the project cannot be continued or even stopped for some reasons, which will cause great losses to the buyers.
② The pre-sale contract of commercial housing is prone to problems. Generally, after signing the pre-sale contract, the buyers get only a kind of expectation right, not the ownership of the house.
