Adjustable-Rate Mortgage (ARM)
A lower rate when it matters most
An adjustable-rate mortgage (ARM) starts with a fixed introductory rate that's typically lower than a 30-year fixed, then adjusts periodically based on a market index. For buyers who plan to sell, move, or refinance before the first adjustment, an ARM can mean real monthly savings with minimal rate risk.
- Lower initial rate than 30-year fixed
- Fixed for 5, 7, or 10 years initially
- Rate caps limit how much rates can move
- Ideal for shorter planned ownership horizons
Why choose this loan
Benefits of a Adjustable-Rate Mortgage (ARM)
Meaningful savings in the fixed period
ARM start rates are typically 0.5–1.0% below comparable 30-year fixed rates. On a $500,000 loan that can translate to $250–$400 less per month during the fixed introductory window.
Built-in rate caps protect you
Federal regulations require periodic and lifetime caps on ARM adjustments. A common structure is a 2/2/5 cap — rates can only rise 2% at first adjustment, 2% per subsequent adjustment, and no more than 5% over the life of the loan.
Smart match for shorter time horizons
If you expect to sell, relocate, or refinance within five to seven years, you may never reach the first adjustment date — capturing all the savings with none of the variability.
Potential rate decreases too
If market interest rates fall, your ARM rate may adjust downward, reducing your payment without the cost and hassle of refinancing.

Frequently asked questions
How does a 5/1 ARM work exactly?
The '5' means your rate is locked for the first five years. The '1' means it can adjust once per year after that, based on a margin added to a benchmark index (typically SOFR). Rate caps limit how large each adjustment can be.
What are ARM rate caps and how do they protect me?
A standard 2/2/5 cap structure means: the first adjustment can't exceed 2%, subsequent annual adjustments can't exceed 2%, and the rate can never rise more than 5% above your initial rate over the life of the loan.
Can I refinance out of my ARM before it adjusts?
Yes — and many borrowers do exactly that. If rates have fallen or your equity has grown, refinancing into a fixed-rate loan before the first adjustment is a common and straightforward strategy.
Do I qualify at the start rate or the fully adjusted rate?
Under current ATR/QM rules, lenders qualify ARM borrowers at the fully indexed rate (index + margin), not just the teaser start rate. This protects you from being approved for a payment you couldn't sustain after adjustment.
