Adjustable-Rate Mortgages for Washington Buyers

An adjustable-rate mortgage starts with a fixed rate for 5, 7, or 10 years, then adjusts every six months with the market. The lower starting rate can make a real difference in today's rate environment, especially if you expect to sell, refinance, or move before the fixed period ends. Marc Hendrickson will show you the worst-case payment, not just the starting one.

How ARM Caps Work

How the rate can change, in plain numbers

Every ARM has caps that limit how far the rate can move. Most conforming ARMs today use one of two cap structures, written as three numbers: the first adjustment, each later adjustment, and the lifetime maximum.

ARM typeFixed periodCaps (first / later / lifetime)What that means
5/6 ARM5 years2% / 1% / 5%The first adjustment can move the rate up to 2 points, later adjustments up to 1 point every six months, and it can never rise more than 5 points above the start rate.
7/6 ARM7 years5% / 1% / 5%The first adjustment can use the full 5-point lifetime cap, then up to 1 point every six months after that.
10/6 ARM10 years5% / 1% / 5%Same caps as the 7/6, with three more years of fixed payments up front.

These are the standard cap structures for conforming SOFR ARMs. Always check the specific loan disclosure.

Example: a 5/6 ARM that starts at 6.00%

  • Years 1 to 5: 6.00%, fixed.
  • First adjustment: no higher than 8.00%.
  • Later adjustments: up to 1 point every six months.
  • Lifetime maximum: 11.00%.

The rate can also come down if the market does. Marc will show you the payment at the start, at the first adjustment, and at the lifetime cap, so there are no surprises.

When an ARM Makes Sense

Built for buyers with a shorter timeline

An ARM is a bet that you'll be out of the loan, or into a new one, before the fixed period ends. For the right buyer, that bet is a good one.

You Plan to Refinance

If you expect rates to fall or your finances to change, an ARM's lower start rate can carry you until you refinance into a fixed rate. Refinance options.

You Want a Lower Payment Now

A lower starting rate frees up monthly cash for the first several years, which can matter on a larger loan.

How the Rate Is Set

Index plus margin: where an ARM rate comes from

Once the fixed period ends, your rate isn't set by the lender's mood that day. It follows a published formula you can check yourself.

The Margin

A fixed number of percentage points added to the index. It's set when you take out the loan and never changes, so it's worth comparing between offers.

The Fully Indexed Rate

Index plus margin equals your new rate at each adjustment, limited by the caps. If the index is 4.00% and your margin is 2.75%, the formula rate is 6.75%.

Comparing Your Options

ARM, fixed rate, or buydown?

An ARM is one of several ways Marc helps buyers manage today's rates. Here's how it compares with the alternatives.

ARM vs. 30-Year Fixed

A fixed rate never changes, which is worth paying for if you'll stay put for a long time. An ARM costs less up front if you won't.

ARM vs. Temporary Buydown

A 2-1 or 1-0 buydown lowers your rate for the first year or two while keeping a fixed rate long term. Sellers often pay for it as a concession.

ARM vs. Permanent Buydown

Paying points at closing lowers a fixed rate for the life of the loan. It makes the most sense if you'll keep the loan past the break-even point.

Jumbo ARMs

Adjustable rates are common on larger loans, where the payment difference is biggest. Jumbo loans.

Qualifying for an ARM

Lenders qualify 5/6 borrowers at the higher of the fully indexed rate or the start rate plus 2 points, which builds in a cushion.

Getting Out Later

You can refinance out of an ARM into a fixed rate at any time, subject to qualifying and closing costs.

ARM FAQ

Common questions about adjustable-rate mortgages

When does an ARM make sense?

Typically when you plan to sell, refinance, or move before the fixed period ends. If you'll keep the home for decades, a fixed rate is usually the safer choice.

What happens when the fixed period ends?

The rate starts adjusting every six months based on the index plus a fixed margin, within the loan's caps.

What is SOFR?

The Secured Overnight Financing Rate, a benchmark based on overnight lending backed by Treasury securities. Conforming ARMs use its 30-day average as their index.

How do ARM caps work?

Caps limit how much the rate can move at the first adjustment, at each later adjustment, and over the life of the loan. A 5/6 ARM commonly uses 2/1/5 caps, while 7/6 and 10/6 ARMs use 5/1/5.

Can my rate go down?

Yes. If the index falls, your rate can adjust down at the next change date, though many ARMs won't go below the margin.

How do lenders qualify me for an ARM?

For a 5/6 ARM, lenders qualify you at the higher of the fully indexed rate or the start rate plus 2 points. For 7/6 and 10/6 ARMs, it's the higher of the fully indexed rate or the start rate.

Is an ARM riskier than a fixed-rate loan?

It carries more rate uncertainty over time, which is why it fits best when you have a clear shorter-term plan for the home.

Should I consider a buydown instead of an ARM?

Possibly. A temporary or permanent buydown can lower your payment while keeping a fixed rate. Marc can compare both for your situation.
