The transfer process of unpaid mortgaged houses:
1. Pay off the remaining loan with the buyer's down payment. Second-hand housing transaction is the most common and convenient way. Applicable to the case that the original owner's loan amount is low or the remaining loan amount is small;
2. Refinancing (transferring the loan to the buyer). If you want to borrow money to sell a house, you need to transfer the mortgage to the buyer so that the buyer can continue to repay the seller's mortgage;
3. Refinancing to repay the remaining loans. Neither of the above two situations is feasible, and the seller can consider applying for a mortgage loan from the bank or the fund supervision institution with the collateral under his name to pay off the mortgage loan.
