The house payment should be supervised as much as possible to ensure safety;

If it is a loan to buy a house, you should confirm your loan ability and loan qualification in advance;

If the purchase area is restricted, you need to confirm that you are qualified to buy a house, and do a good job in reviewing the qualification of buying a house in advance;
