Bigger discounts on ARMs have pushed more borrowers to reconsider short-term rate risk
Brokers across the country leaned harder on adjustable-rate mortgages this year as the cost gap with 30-year fixed loans widened to its largest point since 2022, giving payment‑strapped borrowers another way to make deals pencil out.
According to a new Redfin analysis, the typical homebuyer would have cut their monthly payment by about $150 by choosing an adjustable-rate mortgage (ARM) instead of a 30-year fixed loan as of mid‑March.
The report found that borrowers using a 7/6 ARM took on an average rate of 5.51%, compared with 6.19% for a standard 30-year fixed. That's a spread of 68 basis points, the largest since June 2022.
Monthly payments for ARM borrowers averaged $2,578 versus $2,727 for fixed-rate borrowers, a 5.8% discount.
Redfin’s analysis also showed that the typical ARM payment of $2,578 fell roughly 7% from a year earlier, compared with a 5% decline for fixed-rate borrowers.
Over the same period, average ARM rates slipped from 6.38% to 5.51%, while 30‑year fixed rates eased from 6.77% to 6.19%.
ARM discounts revive an old tool for brokers
The Mortgage Bankers Association recently reported that ARM accounted for 8% of volume of total applications.
In several 2024-25 surveys, it climbed to roughly 9–10%, with ARM activity accounting for an even larger share of dollar volume as higher‑balance borrowers sought lower initial rates.

Bill Banfield, chief business officer at Rocket, framed ARMs as one of the few remaining tools to restore affordability.
“Adjustable-rate mortgages are offering meaningful savings in 2026’s expensive housing market,” Banfield said.
“Even though housing costs have recently come down a bit, it remains tough for first-time buyers to break in – and for existing homeowners to walk away from their ultra-low rates. With ARMs providing borrowers with the biggest discount in nearly four years, choosing an ARM could be a gamechanger, saving buyers hundreds of dollars each month and thousands over a few years. ARMs typically make sense when rates are high enough that buyers don’t want to lock them in – like now. When rates are low, like they were during the pandemic, it’s worth locking them in for as long as possible.”
Risk, regulation and the new ARM calculus
For many industry veterans, ARMs still carry the shadow of the subprime crisis. But post‑crisis rules changed how these products were structured and underwritten.
The Consumer Financial Protection Bureau’s ability‑to‑repay and Qualified Mortgage framework require lenders to document a borrower’s capacity to handle higher payments, not just an introductory “teaser” rate, and to qualify many ARM borrowers at a fully indexed or higher rate.
Regulators also pushed clearer guardrails on rate adjustments. Most mainstream ARMs now include periodic and lifetime caps on how far rates and payments could rise, limiting payment shock compared with pre‑2008 structures.
Those protections have not eliminated risk. After the initial fixed period, payments still could rise if benchmark rates move higher, and refinance or sale options remain uncertain in a weaker economy.
But for borrowers expecting to sell, move or refinance within seven to ten years – and for brokers fighting to keep deals alive in a high‑price market – the current discount on ARMs has become difficult to ignore.
