For mortgage loans, according to the provisions of the Banking Law, the Contract Law and the General Principles of the Civil Law, if the debtor fails to repay the bank loan at maturity, the bank has the right to auction the collateral through the court and give priority to compensation according to law.

The insufficient part, the bank has the right to continue to recover from the loan unit or individual.

Among them: if a limited liability company borrows money from a bank in the name of the company and uses the company's property as collateral, and it is unable to pay off after the expiration, the bank can continue to recover the money if the auction collateral is insufficient, but if the limited liability company goes bankrupt, the insufficient part will eventually become bad debts.

However, if it is an individual, the bank can continue to recover from the debtor if it is still insufficient after compensating the price of the collateral.

Note that our country's laws prohibit paying debts in kind. If the debtor is unable to repay the mortgaged creditor's right after it expires, the creditor may demand to auction the mortgaged property for compensation according to law, but it cannot directly pay the debt in kind when it expires.
