Adjustable-Rate Mortgage

An adjustable-rate mortgage is a type of mortgage where the interest rate can change over time, and as a result, the payment amount may also change. The rate is typically tied to a benchmark rate set by the lender and adjusts periodically based on market conditions.

Unlike fixed-rate mortgages, adjustable-rate mortgages expose borrowers to interest rate movements. When rates rise, payments may increase. When rates fall, payments may decrease, depending on how the mortgage is structured.

Why this matters:
Many borrowers focus on the initial rate without fully considering how payment changes could affect their budget. Understanding how adjustable-rate mortgages work helps borrowers assess risk, plan for potential rate increases, and decide whether payment flexibility is worth the uncertainty.
