1, the mortgage loan should have gone through the mortgage registration formalities. It is estimated that their internal inspection found that your property was not mortgaged, so they urged you to go through the mortgage registration. Officially, you go to register with the bank loan officer. Of course, some banks do not register in the housing management department, but leave the real estate license in the bank. The purpose is actually to save the registration fee. After the mortgage registration, the bank will not ask for your real estate license. The real estate department will issue certificates of other projects to the bank to prove that your real estate is being mortgaged. At the same time, you will stamp the mortgage registration seal on the real estate license, indicating the registration time and mortgage period.
