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 go through the transfer formalities directly.
Therefore, the pre-sale contract signed will not be signed when the house is handed over, and the transfer formalities can be directly handled. If the pre-sale contract was signed before1May 3, 9971,it is still necessary to sign the sales contract according to the contract itself before registering in registered permanent residence.
Supplementary agreement:
This supplementary agreement is often something that is not stipulated in the purchase contract, usually stipulated in the supplementary terms. To some extent, the supplementary terms are more important than those agreed in the house sales contract, because the supplementary terms are agreed according to the different specific conditions of different projects. Therefore, we should grasp several issues when signing supplementary terms.
First, it is necessary to clarify the responsibilities of both parties to the mortgage failure. Buying a house usually requires a mortgage. In fact, in some cases, the mortgage loan has not been completed. The reasons for not doing it are very complicated, including the reasons for property buyers, the reasons for real estate developers, even the reasons for banks, and some comprehensive reasons. It is necessary to clarify what the respective responsibilities of both parties are if they cannot apply for a mortgage.
The second is to clarify the time for handling housing ownership certificates. Because the sales contract usually doesn't say how long it will take to complete the title certificate, it is usually agreed in the supplementary terms.
