Generally speaking, there are requirements for the company's registration period, which usually takes six months to more than one year. It depends on the policy of the local branch. Different banks have different requirements.

Is there a requirement for the size of the mortgaged house, the old and new degree, and the proportion of all real estate licenses?

There are also standards for the area and the old and new degree of the house. If the real estate license has multiple names, the mortgage loan needs to be signed by all property owners for confirmation.

The name of the legal person is full house. Can the full house of the spouse and his parents be used as collateral?

Spouses and their parents can also operate the whole house, but the procedures are different.

I don't know what your capital needs are and what your requirements are. I suggest comparing several banks.
