If a person can't go, he must write a power of attorney, notarize it in the notary office, and authorize another person to exercise the right to sign on his behalf.

In addition to signing the power of attorney, you should also bring the house ownership certificate, the copy of the land use right certificate (original inspection), the real estate appraisal report issued by a qualified appraisal agency and the copy of the ID card of the agent (original inspection).

Extended data:

Real estate mortgage means that the property owner takes the deed of house as the mortgage and obtains the loan to pay interest on schedule. The property right of the house is still managed by the property owner himself, and the creditor only takes interest on schedule and has no right to manage the house. After the loan is paid off, the property owner will terminate the mortgage of the deed. When the debtor fails to perform the debt, the creditor has the right to dispose of the mortgaged house according to law, and has the right to receive priority compensation for the proceeds from the disposal of the mortgaged house. The party who provides the mortgaged house is called the mortgagor, and the original creditor who accepts the mortgaged house is called the mortgagor. The mortgagor of a house must have full capacity for civil conduct, and a person without capacity for civil conduct or with limited capacity for civil conduct may not set up a house mortgage.
