A few months ago, we discussed the benefits of Hybrid Arms. The recent increase in mortgage rates has the discussion regarding Hybrid ARMs starting again. The use of 5/1 Hybrid ARMs have increased primarily because they offer significantly lower initial interest rates than 30-year fixed-rate mortgages. With mortgage rates remaining above many borrowers’ comfort levels, buyers are looking for ways to improve affordability and qualify for homes. Recent market data shows 5/1 ARM rates running roughly 0.7% to 1.0% below comparable 30-year fixed rates, creating meaningful monthly payment savings.
The Mortgage Bankers Association recently reported that ARM applications accounted for nearly 10% of all mortgage applications, the highest share since late 2025. According to MBA economists, borrowers are increasingly selecting ARMs because the ARM rate advantage is significantly below the 30-year fixed rate.
Another factor is borrower’s expectations regarding future interest rates. Many homebuyers believe that if rates decline over the next several years, they may be able to refinance before the ARM begins adjusting. A borrower choosing a 5/1 ARM today receives a fixed rate for five years, providing time for potential rate improvements while benefiting from a lower payment immediately.
ARMs have also become attractive to buyers who do not expect to remain in the home for the long term. First-time buyers, move-up buyers, and relocating professionals often anticipate selling or refinancing within five to seven years. For these borrowers, the lower initial rate may outweigh the future adjustment risk. Community discussions among borrowers frequently cite planned moves, expected promotions, or anticipated refinancing opportunities as reasons for choosing a 5/1 ARM.
From a mortgage underwriting perspective, the increase in ARM usage is largely an affordability story. As home prices remain elevated and fixed mortgage rates stay above historical lows, borrowers are using 5/1 Hybrid ARMs to lower monthly housing expenses, improve debt-to-income ratios, and qualify for larger loan amounts. For borrowers who understand the adjustment risk and have a clear exit strategy, the product can be an effective financing tool. However, lenders should ensure borrowers are qualified based on the fully indexed rate requirements applicable to the loan program and understand the potential payment changes after the fixed-rate period expires.
