Adjustable-rate mortgages have regained market share as the spread between 5/1 ARM rates and 30-year fixed rates has widened to over 1.5 percentage points, creating meaningful savings for borrowers who understand the trade-offs.
Context
ARMs fell out of favor during the low-rate era when fixed rates below 3% made adjustable products unnecessary. Now, with 30-year fixed rates near 6.5%, the 5/1 ARM at roughly 5% is attracting borrowers who plan shorter tenures or expect rates to decline.
Details
The 5/1 ARM offers a fixed rate for five years before adjusting annually based on the SOFR index plus a margin. Rate caps typically limit adjustments to 2% per period and 5% over the loan's life. The 7/1 and 10/1 ARM products provide longer initial fixed periods at slightly higher rates.
Impact
On a $400,000 mortgage, choosing a 5/1 ARM at 5.0% over a 30-year fixed at 6.5% saves approximately $375 per month during the initial fixed period—totaling over $22,000 in the first five years.
Analysis
ARMs make the most financial sense for borrowers who are confident they will sell or refinance within the initial fixed period. Military families, corporate relocators, and buyers in appreciating markets are prime candidates.
Outlook
If the Fed follows through on projected rate cuts, ARM holders could see their rates adjust downward at the first reset, potentially making these products even more attractive in retrospect.
