The so-called maximum mortgage refers to the agreement between the mortgagor and the mortgagee to guarantee the creditor's rights that occur continuously for a certain period of time with collateral within the maximum creditor's rights limit.

For example, the seller will continue to supply the seller for a period of time. As long as the buyer wants it, the seller will give it, and the price will be settled at the end of the month and paid in one lump sum. Therefore, the price cannot be determined during the supply period. The buyer provided the factory building as collateral, worth 200,000 yuan. So the maximum mortgage value is 200 thousand. If the debt cannot be repaid at maturity, if 250,000 yuan is paid, the seller can only give priority to the property of 200,000 yuan.
