After paying off the house, the house can't be untied. What does it mean to let real estate go free in summer?

The so-called solution is to go to the real estate center to handle the formalities of decompression and filing of the real estate license. In this way, the real estate license can be used for trading normally.

The mortgage has been paid off, and the formalities for canceling the real estate license shall be handled by the lending bank.

Because before lending, the developer issues the purchase contract and related materials, handles the real estate license, and then the bank takes it to the real estate center to do the mortgage pledge formalities for the record before lending.

Is the real estate license transferred from the developer to the buyer or kept by the bank? After the mortgage is paid off, the bank applies for cancellation of mortgage filing procedures, and then gives property ownership certificates to the buyers.
