If the loan has been approved by the bank, the buyer and the seller can only wait patiently for the loan at this time;

If the loan is not approved, the buyer and the seller can negotiate how to pay the final payment. If the buyer really can't pay the final payment, he can only terminate the contract according to the relevant provisions of the contract.

Secondly, if you buy a house through an intermediary, the borrower can put pressure on the intermediary to urge the bank to lend as much as possible in a short time.

If you really can't do it and want to buy a house, you can also ask a third-party guarantee company for assistance.
