Debt secured by real property, whether viewed as a single borrower's mortgage balance or as a broader category of housing-related leverage.
Mortgage debt is debt secured by real property, usually a home, apartment building, or commercial real estate asset.
The term can refer to one borrower’s outstanding mortgage balance or to mortgage borrowing as a broader category in the economy.
Mortgage debt matters because it is often the largest liability on a household balance sheet. At the system level, changes in mortgage debt affect housing affordability, leverage, bank exposure, and sensitivity to rate changes.
The borrower receives funds and pledges the property as collateral. If the borrower fails to meet the repayment terms, the lender may have foreclosure or other enforcement rights against the property.

Mortgage debt can be fixed-rate or variable-rate, amortizing or non-amortizing, and owner-occupied or investment-related.
A homeowner buys a property with a mortgage and still owes $240,000 several years later. That remaining secured liability is the homeowner’s mortgage debt.
Mortgage debt is secured by property, which changes both lender risk and borrower consequences in default.
The term can describe both one loan on one property and a whole category of leverage in the financial system.
Mortgage: Core loan structure that creates the debt.
Loan-to-Value Ratio: Key measure of leverage against the secured property.
Collateral: The property interest supporting the debt.
Mortgagor: The borrower responsible for repaying the debt.
Foreclosure: Main enforcement path if the debt is not repaid.
