Deficiency judgment in the context of "Mortgage law"

A secured loan is a loan in which the borrower pledges some asset (e.g. a car or property) as collateral for the loan, which then becomes a secured debt owed to the creditor who gives the loan. The debt is thus secured against the collateral, and if the borrower defaults, the creditor takes possession of the asset used as collateral and may sell it to regain some or all of the amount originally loaned to the borrower. An example is the foreclosure of a home. From the creditor's perspective, that is a category of debt in which a lender has been granted a portion of the bundle of rights to specified property. If the sale of the collateral does not raise enough money to pay off the debt, the creditor can often obtain a deficiency judgment against the borrower for the remaining amount.

The opposite of secured debt/loan is unsecured debt, which is not connected to any specific piece of property. Instead, the creditor may satisfy the debt only against the borrower, rather than the borrower's collateral and the borrower. Generally speaking, secured debt may attract lower interest rates than unsecured debt because of the added security for the lender; however, credit risk (e.g. credit history, and ability to repay) and expected returns for the lender are also factors affecting rates. The term secured loan is used in the United Kingdom, but the United States more commonly uses secured debt.
