After signing the subscription book, the next step is to sign a formal purchase contract. At the proposed time and place, the purchaser prepares all the documents and formally signs the purchase contract with the developer or agent. The purchase contract generally includes two types: the pre-sale contract of commercial housing (auction house) and the sale contract of commercial housing (existing house). The difference between the two is that the pre-sale contract is adopted for the pre-sale of commercial housing, and the house is delivered after completion. After the buyer has paid off all the house payment, he can directly handle the transfer. Commercial housing sales contracts are applicable to the sale of existing commercial housing (commercial housing that has passed the acceptance and obtained the title certificate).
