You'd better consult the housing management network, which is actually the local real estate trading center.
Ask them if they are the most authoritative, and the policies vary from place to place.
In some places, it is forbidden to change the contract name of pre-sale houses in order to prevent scalpers from speculating in real estate.
Therefore, once the pre-sale contract is signed, the name cannot be changed.
Policies such as loans for first-hand housing sales are different from those for second-hand housing. Others are no different.
If they cheat you into signing a second-hand house contract, it is estimated that the first-hand house will be turned into a second-hand house at a higher price and sold to you to make money.
If you just change the name of the pre-seller of the first-hand house. That might be okay.
In short, you can get the change information of the first-hand house on the website of the real estate trading center.
Be careful.
