The down payment on the house was paid and the mortgage came down. Should I go to the Housing Authority for filing?

If the bank has lent money after the down payment for buying a new house, then the developer will go to the Housing Authority for the buyer's record, and the buyer can go to the Housing Authority to inquire. The query method is as follows:

Property owner with ID card;

Inquire in the self-service file inquiry machine of the Housing Authority;

Put the ID card into the sensing area of the document retrieval machine;

Select the house information under the query name;

If you find house information, it is already on file, and vice versa;
