What Is a Mortgage

A mortgage is a loan used to buy real estate, most often a home. The borrower repays the loan over time, and the property itself usually serves as security for the lender.

Because the loan is tied to property, mortgages are treated differently from many other borrowing products.

Definition: a mortgage is a secured home loan where the property backs the debt.

How a mortgage works

When you buy a home with a mortgage, the lender provides most of the purchase money upfront. You then repay that amount through scheduled payments over a long period.

Those payments usually include repayment of the loan principal plus interest, and sometimes other housing-related costs depending on the setup.

Why the property matters

A mortgage is secured by the home or property itself. That lowers lender risk compared with some unsecured borrowing products.

This is also why mortgages often involve detailed approval checks, including income review, debt review, and credit score assessment.

What borrowers compare

People comparing mortgages often look at interest rate, APR, loan term, monthly payment, required down payment, and total long-term cost.

A lower monthly payment may still mean higher total cost if the loan runs much longer or carries extra charges.

Why mortgages feel different from smaller loans

Mortgages are usually much larger than ordinary consumer loans, and the repayment timeline is much longer. That makes the borrowing decision more sensitive to small rate changes and fees.

It also means buyers need to think beyond approval and ask whether the payment fits the broader budget comfortably.

Summary

A mortgage is a loan used to buy property and secured by that property. Understanding how it works helps borrowers compare real housing costs instead of focusing only on the home price.
