Adjustable-Rate Mortgage (ARM)

An adjustable-rate mortgage starts with a fixed rate that is often lower than a 30-year fixed, then adjusts periodically. It can be a smart choice if you plan to move or refinance within several years.

What is an Adjustable-Rate Mortgage?

An ARM has an initial fixed period, commonly 5, 7 or 10 years, followed by rate adjustments based on a market index plus a set margin. A 7/6 ARM, for example, is fixed for seven years and then adjusts every six months. Caps limit how much the rate can change at each adjustment and over the life of the loan.

Lower initial rate

Start with a rate that is often below fixed-rate options.

Rate caps

Built-in limits on how much your rate can rise.

Flexible terms

Choose 5, 7 or 10-year initial fixed periods.

Refinance option

Move to a fixed rate later if it makes sense.

How adjustments work

After the fixed period, your new rate equals an index plus a margin, subject to caps. Your loan documents list the index, margin and every cap so you know the worst case in advance.

Understanding rate caps

ARMs typically have three caps: one for the first adjustment, one for each later adjustment and one for the life of the loan. We will show you the maximum possible payment before you commit.

ARMs are described with numbers like 5/6 and caps like 2/1/5:

  • 5/6 means the rate is fixed for 5 years, then adjusts every 6 months
  • The first number in the cap is the most the rate can rise at the first adjustment
  • The second is the most it can rise at each later adjustment
  • The third is the most it can ever rise above the start rate

After the fixed period, the rate equals an index such as SOFR plus a set margin, within those caps.

When an ARM makes sense

ARMs fit buyers who expect to sell, relocate or refinance before the fixed period ends, and jumbo borrowers who want lower initial payments.

If you are confident you will sell or refinance before the fixed period ends, an ARM can save meaningful money. We will show you the worst-case payment so you know the risk before you choose.

Adjustable-Rate Mortgage FAQs

Have a question that is not answered here? Ask a loan officer.

Can my payment go down?

Yes. If the index falls, your rate can adjust downward, subject to the loan's floor.

What does 7/6 mean?

Fixed for the first seven years, then adjusts every six months.

Can I refinance an ARM into a fixed rate?

Yes, as long as you qualify at the time.

Are ARMs risky?

They carry more payment uncertainty than a fixed loan, which is why caps and a clear plan matter.

Can I refinance out of an ARM?

Yes. Many borrowers refinance into a fixed rate before the first adjustment, subject to qualifying at that time.
