Legal analysis: According to the housing mortgage loan policy, if the borrower has no real estate under his name, he can apply for a loan with the real estate under someone else's name as collateral, but he needs to obtain the consent of the owner of the house and issue a letter of commitment to agree to the mortgage, otherwise the mortgage will be invalid. Therefore, as long as parents agree to apply for a loan with their own property as collateral, they can apply. However, not all properties can apply for mortgage loans. Only houses with real estate license and state-owned land use certificate, which are within 20 years old and can be listed and traded normally, can apply for loans.

Legal basis: Article 394 of the Civil Law of People's Republic of China (PRC) guarantees the performance of debts. If the debtor or a third party mortgages the property to the creditor without transferring the possession of the property, the debtor fails to perform the due debt or the creditor has the right to receive priority compensation for the property. The debtor or the third party specified in the preceding paragraph is the mortgagor, the creditor is the mortgagee, and the property that provides guarantee is the mortgaged property.
