Most ARMs require a 620 minimum credit score. Better scores get better margins — that's the multiplier added on top of the index at adjustment.
Lenders qualify ARM borrowers at the fully indexed rate, not the teaser rate. Your debt-to-income ratio must hold up at the higher number.
ARM pricing varies significantly across lenders. The index used, the margin, and the caps all differ — those details determine your worst-case rate.
At SRK CAPITAL, we shop ARMs across 200+ wholesale lenders. We compare initial rates, margins, and cap structures side by side before recommending one.
ARMs make sense when you have a clear exit — selling, refinancing, or paying down before the fixed period ends. Without a plan, the risk is real.
A 5/1 ARM in Merced bought you time at a lower payment. If you're confident in your 5-year timeline, that spread matters.

The rate is fixed for 5 years, then adjusts once per year. Your payment stays predictable during that initial window.
Rate caps control this. Most ARMs have a per-adjustment cap and a lifetime cap — ask your lender for both numbers upfront.

Yes, but refinancing costs money and depends on rates at the time. Don't assume a refi will always be available or affordable.
They can. Investors who plan to flip or hold short-term may benefit from lower ARM payments during their hold period.
Most ARMs today use SOFR as the benchmark index. Your margin is added on top of that index at each adjustment.
