ARM vs. Fixed-Rate Mortgage: Which Is Right for You?

The choice between an adjustable-rate mortgage (ARM) and a fixed-rate loan comes down to a trade-off between a lower starting payment and long-term certainty.

Fixed-rate: predictable for life

Your principal-and-interest payment never changes, no matter what rates do. It's the simplest choice and the safest if you'll keep the home a long time or want zero surprises.

ARM: lower now, variable later

An ARM (like a 5/1 or 7/1) offers a lower fixed rate for an initial period, then adjusts periodically with the market. The early savings are real, but your payment can rise after the fixed period ends.

When an ARM can make sense

• You expect to sell or refinance before the fixed period ends.
• You want lower payments now and can absorb a future increase.
• The rate gap between ARM and fixed is large enough to matter.

When to lock in fixed

If you value certainty, plan to stay put, or rates are historically low, fixed is usually the smarter long-term call. A broker can price both for your scenario so you see the real numbers, not generalities.
