Also known as: ARM, variable-rate mortgage

Quick Summary

An adjustable-rate mortgage (ARM) is a home loan where the interest rate can change periodically, typically after an initial fixed period. This means your monthly payments can increase or decrease over the life of the loan, unlike a fixed-rate mortgage where the payment remains consistent.1

ARMs often start with a lower "teaser rate" than fixed-rate loans, which can save money initially. However, after the fixed period, the rate adjusts based on market conditions, tied to an index rate plus a margin set by the lender. Federal law requires ARMs to have caps that limit how much the interest rate can increase at each adjustment and over the loan's lifetime, protecting borrowers from extreme payment hikes.1

An ARM might be suitable if you plan to sell the home before the fixed period ends, if the initial rate offers significant savings, or for larger loan amounts where even small rate differences matter. However, the risk of rising payments after the fixed period requires careful consideration of your budget and risk tolerance.1
