Legal analysis: it can be sold. The house has been mortgaged, and the mortgagor, the property owner, can still sell the house. That is to say, the mortgaged house can be sold, and the mortgage can go with the house, which means that it can be sold together with the mortgage. Mortgage does not affect the transaction flow of real estate, and the consent of the mortgagee is not required for the sale of the house, but the property owner must inform the mortgagee when selling the house.

Legal basis: Article 406 of the Civil Code of People's Republic of China (PRC). During the mortgage period, the mortgagor may transfer the mortgaged property. Unless otherwise agreed by the parties, such agreement shall prevail. If the mortgaged property is transferred, the mortgage right will not be affected. Where the mortgagor transfers the mortgaged property, it shall promptly notify the mortgagee. If the mortgagee can prove that the transfer of the mortgaged property may damage the mortgage right, he may require the mortgagor to pay off the debt or deposit the proceeds of the transfer in advance with the mortgagee. The part of the transfer price exceeding the amount of creditor's rights belongs to the mortgagor, and the insufficient part is paid off by the debtor.
