ARM vs Fixed-Rate Mortgage: Which Should You Choose in 2026?

Full transcript

The verdict up front

The thirty year fixed remains the right default for buyers keeping a home — or at least a mortgage — beyond about seven years: one payment, zero rate risk, refinance optional if rates fall. A five six or seven six ARM earns its keep for genuinely short horizons — relocation track careers, planned upsizing, bridge situations — where twenty twenty six's ARM discount of roughly half a point buys real monthly savings during exactly the years you'll own the loan. The honest test: if you can't say when you'd exit, you're a fixed rate borrower.

How the ARM actually works

A five six ARM holds its intro rate five years, then adjusts every six months off the SOFR index plus a margin. The caps are the fine print that matters: typically two percent at the first adjustment, one percent per adjustment after, five percent lifetime. So a worst case is your intro rate plus five points — a number you should be able to afford before you sign, because lenders qualify you above the intro rate for exactly that reason.

Who each one fits

The ARM case needs three things: a concrete exit inside the intro window — orders, a residency, a planned sale; a discount that meaningfully cuts the payment now; and the ability to absorb the first adjustment cap if plans slip. The fixed case is everyone else — a long or honestly unknown horizon, a budget that values certainty, and the preference for falling rates to be pure upside through an optional refinance rather than a forced exit strategy.

The close

Run the arithmetic honestly: half a point on your loan size, times the years you'd genuinely hold it, against the risk of still owning the loan at adjustment. If the exit is real, the ARM discount is yours to take. If it's a hope, buy the fixed and sleep. The full comparison and FAQ are free at dreamy leads dot com.
