Today's Adjustable Rate Mortgages (ARM) Rates

What Is a Adjustable Rate Mortgages (ARM) Loan?
An Adjustable Rate Mortgage (ARM) is a home loan with an interest rate that changes over time based on market conditions. ARMs start with a fixed-rate introductory period — the "7" in a 7/1 ARM means your rate stays fixed for the first 7 years. After that, the rate adjusts once per year (the "1") based on a benchmark index plus a margin set by your lender. ARMs typically offer lower initial rates than fixed-rate mortgages, making them attractive for buyers who don't plan to stay in the home long-term or expect rates to decrease.
Who Qualifies?
ARM qualification requirements are similar to fixed-rate conventional loans. You'll need a minimum credit score of 620 (700+ for the best ARM rates), a debt-to-income ratio below 45%, and a down payment of at least 5% (conventional ARM) or 3.5% (FHA ARM). Lenders will qualify you at the fully-indexed rate (not just the introductory rate) to ensure you can handle potential payment increases. Strong income stability and cash reserves improve your chances of approval.
