The Bottom Line

Choose a fixed rate mortgage if you plan to stay long-term and want payment certainty. Choose a variable rate (ARM) if you plan to move or refinance within 5-7 years and want lower initial payments. In the current 2026 rate environment, fixed rates offer security while ARMs offer short-term savings.

Frequently Asked Questions

What does 5/1 ARM mean?

The rate is fixed for the first 5 years, then adjusts once per year after that. Common ARMs include 3/1, 5/1, 7/1, and 10/1.

Can my ARM rate increase without limit?

No. ARMs have caps: a per-adjustment cap (usually 2%), an annual cap, and a lifetime cap (usually 5-6% above the initial rate).

Should I get a fixed rate in 2026?

With rates between 6.5-7%, a fixed rate makes sense for long-term homeowners. If you expect rates to drop and plan to refinance or move within 5 years, an ARM may save money.
