Housing authority. After the housing loan is settled, go to the Housing Authority to understand the mortgage situation. After the mortgage is paid off, if you want to apply for a mortgage, you must first apply to the loan handling bank for a loan settlement certificate, get back his other warrants, and then bring relevant information to the Housing Authority for cancellation of mortgage registration. As long as the information is handed over to the staff, the staff will review the information and release it on the spot after confirming that it is correct.
