Question 1

How long is the fixed period on an ARM?

Accepted Answer

Most ARMs have a fixed period of 5, 7, or 10 years. After that, the rate adjusts annually based on a market index. A 7/1 ARM means 7 years fixed, then adjusts once per year.

Question 2

Is an ARM risky?

Accepted Answer

It depends on your plans. If you expect to sell or refinance within the fixed period, an ARM can save you significant money vs. a fixed rate. ARMs also have rate caps that limit how much the rate can increase.

Question 3

What does '5/1' or '7/6' ARM mean?

Accepted Answer

The first number is how many years the rate stays fixed. The second is how often it adjusts after that. A 7/6 ARM is fixed 7 years, then adjusts every 6 months.

Question 4

How much can my ARM rate increase?

Accepted Answer

All ARMs have caps: an initial cap on the first adjustment, a periodic cap on each subsequent adjustment, and a lifetime cap. Common caps are 2/2/5 or 5/2/5.

Question 5

What index does an ARM use?

Accepted Answer

Most modern ARMs use SOFR (Secured Overnight Financing Rate) plus a margin — typically 2.75%. LIBOR-based ARMs are being phased out.

Question 6

Can I refinance out of an ARM later?

Accepted Answer

Yes — and many borrowers do, before the fixed period ends. If rates have dropped or you're staying longer than expected, refinancing into a fixed rate is straightforward.

Question 7

Are ARM rates really lower than fixed?

Accepted Answer

Usually 0.25–0.75% lower at the start. Over a 7-year fixed period, that can save tens of thousands in interest if you sell or refinance before it adjusts.

Question 8

Who shouldn't use an ARM?

Accepted Answer

Anyone planning to stay in the home long-term who values payment stability. If you can't comfortably afford the payment if rates rose, stick with a fixed rate.
