Lower initial rate than a fixed mortgage. Rate adjusts after the initial period. Available in 7 states.
An adjustable-rate mortgage (ARM) is a home loan with an interest rate that stays fixed for an initial period and then adjusts periodically based on market conditions. Common ARM structures include 5/1, 7/1, and 10/1, where the first number is the fixed-rate period in years and the second is how often the rate adjusts after that. ARMs typically offer a lower starting rate than a 30-year fixed mortgage.

Adjustable-rate mortgages can offer advantages depending on your situation:
These features can make ARMs attractive for borrowers who value lower upfront costs or anticipate future changes.
After the initial fixed-rate period ends, the interest rate on an ARM adjusts at scheduled intervals. Rate changes are based on a financial index plus a set margin.
Most ARMs include caps that limit how much the rate can increase:
These caps help limit payment changes over the life of the loan.
An ARM is a strong option for borrowers who plan to sell or refinance before the fixed period ends. If you expect to move within 5 to 10 years, the lower initial rate of an ARM reduces your monthly payment and total interest paid during the time you own the home. An ARM is not the right fit for borrowers who plan to stay long term and want rate certainty

An ARM can offer flexibility and lower initial costs, but it also comes with potential rate changes over time. Understanding how adjustments work and how long you plan to stay in the home is critical when evaluating this option.
A personalized review helps determine whether an adjustable-rate mortgage aligns with your homeownership strategy.
Common questions about how ARM loans work, how rates adjust, and when they make sense.
ARM rate changes are limited by caps built into the loan. The initial adjustment cap limits how much the rate can change at the first adjustment. The periodic cap limits changes at each subsequent adjustment. The lifetime cap limits the total rate increase over the life of the loan. Most ARMs have a 2% initial cap, 2% periodic cap, and 5% lifetime cap, though terms vary by program and lender.
An ARM carries more payment uncertainty than a fixed-rate mortgage because your payment can change after the initial period. The risk depends on how long you plan to keep the loan. If you plan to sell or refinance before the rate adjusts, the risk is minimal. If you plan to stay in the home long term, a fixed-rate mortgage offers more predictability.
