What Is a Mortgage?

A mortgage is a loan used to buy real estate. The property acts as collateral, which means the lender can take legal action if payments are not made as agreed. For most buyers, a mortgage makes homeownership possible by spreading the purchase cost over many years.

How Mortgages Work in Plain Language

When you borrow money for a home, you agree to repay the amount borrowed (principal) plus interest. Payments are usually monthly. Early in the loan, a larger portion of each payment goes toward interest. Over time, more goes toward principal. This process is called amortization.

Core Mortgage Terms Beginners Should Know

Principal

The amount you borrow after your down payment.

Interest Rate

The yearly cost of borrowing. Even small rate changes can impact monthly payment significantly. Test scenarios with the Mortgage Calculator.

Loan Term

Common terms are 15 and 30 years. Shorter terms usually mean higher monthly payments but lower total interest paid.

Simple Example

If you borrow $300,000 at 6.5% for 30 years, your monthly principal-and-interest payment is much lower than a 15-year version, but the 30-year option usually costs more in total interest. Scenario testing is critical before choosing.

Before You Apply

Review your credit profile, stabilize income documentation, and estimate a realistic monthly budget including taxes and insurance. Your lender may approve more than you are comfortable paying, so use your own affordability threshold first.
