Homeowners with some tolerance for uncertainty might find that an adjustable-rate mortgage is worth considering as a way to get a low introductory rate before the adjustments kick in. This loan type can be a particularly good choice if you’re aiming to rent out for flip the property, or when you know you intend to move before the loan’s fixed-rate period ends.
Keep reading and we’ll explain how ARMs work, consider when an ARM is worth considering as an alternative to a fixed-rate mortgage, and look at ARM rates from a few top lenders.

ARM mortgage rates at top lenders
Fortune reviewed the most recent data available as of April 1. These are sample rates provided by the institutions. Each one is based off specific assumptions about a hypothetical borrower’s credit profile and location. Estimates may include an assumption of mortgage discount points.

A 7/6 ARM is one with a fixed rate for seven years, then adjustment periods every six months.
Fixed-rate vs. adjustable-rate mortgages
Fixed-rate mortgages dominate U.S. households, comprising about 92% of all home loans. Unlike adjustable-rate mortgages (ARMs), which allow interest rates to change after an initial period, fixed-rate loans offer consistency throughout their term—which likely explains their popularity.
That said, ARMs can be advantageous under specific circumstances. Around 8% of borrowers choose them for their unique benefits.
When you might consider an adjustable-rate mortgage
Three groups of homebuyers can commonly benefit from considering ARMs:
- Homeowners who intend to move soon: If you’re confident you’ll be moving in a few years, perhaps because this is a starter home, an ARM may let you enjoy a low introductory rate without worrying about future adjustments.
- Real estate investors: Landlords buying a property to rent out or house flippers intending to sell a property quickly may use ARMs with the intent of adjusting the monthly rent if interest rates increase or selling before the adjustment period kicks in.
- Buyers in high-interest environments: During times of elevated interest rates, ARMs can sometimes offer lower rates during the introductory period, and the potential for relief later if market conditions improve.
How adjustable-rate mortgages work
ARMs begin with an introductory fixed rate that often lasts three, five, seven, or 10 years before the loan transitions into its adjustment periods. How much your rate changes during an adjustment period can depend on a variety of factors, including:
- Benchmarks like SOFR: An ARM’s rate is typically tied to a benchmark, commonly SOFR. This particular benchmark reflects the cost for banks to borrow money overnight. The U.S. Treasury publishes an updated each morning.
- Margins: Fixed margins are added by lenders on top of the benchmark to determine your ARM rate. These can often range between 2% to 3.5%.
- Caps: Adjustment caps limit how much rates can increase at specific intervals or over time. You may hear about initial adjustment caps, subsequent caps, and lifetime caps.
Common ARM formats include 5/1 (an introductory rate that lasts for five years followed by annual adjustments) and 10/6 (a 10-year intro period followed by adjustments every six months) structures. Other structures on the market include 3/1 ARMs, 7/1 ARMs and 10/1 ARMs.

Refinancing from an ARM to a fixed-rate mortgage
Life happens. Plans change. If it turns out you’re going to be in your starter home longer than expected, and you initially took out an ARM, you might opt to refinance to a fixed-rate loan.
First, know you’re not alone. A large chunk of Millennial and Gen Z homeowners can’t afford to upgrade and are continuing on in their starter homes
To refinance from an ARM to a fixed-rate mortgage, the process is more or less the same as refinancing from one fixed-rate loan to another. You’ll shop around with various lenders, provide the application documents necessary to show your credit profile and income meet the lender’s requirements, and you’ll use the new loan to pay your old one off in full.
