What percentage of mortgages are adjustable rates in 2022?

In mid-2022, adjustable-rate mortgages made up nearly 10% of all new home loan applications, according to the Mortgage Bankers Association (MBA).

That may not sound like a lot, but it’s a far greater share of ARM loans than we’ve seen since 2008. And it’s easy to see why – with ARM rates hovering more than 100 basis points (1%) below fixed mortgage rates, home buyers in 2022 are leveraging adjustable-rate loans to lower their payments and afford more expensive homes.

ARMs are much cheaper in the short term

PRO TIP: One of the key benefits of an ARM is the initial interest rate is typically about 1.23% lower than a fixed-rate loan. Therefore, the monthly mortgage payment during the introductory period is lower with an ARM than with a fixed-rate mortgage.

The low-rate ARM trend is nothing new. Throughout 2022, even as interest rates have risen sharply, average adjustable rates have stayed around a percentage point or more below fixed mortgage rates.

A 5/1 ARM means the mortgage has its initial fixed rate for the first five years, and then the rate can adjust once per year for the remaining 25 years. Other common options include a 7/1 or 10/1 ARM, meaning your initial rate is fixed for seven or 10 years before it can adjust.

So, you could save a small fortune in monthly payments by opting for an ARM, at least over the first five to 10 years of your loan. Alternatively, you could afford a much nicer, more costly home with the same payments you’d make on a smaller, fixed-rate mortgage.

Of course, an ARM isn’t for everyone. If you plan to stay in your home longer than 10 years, an ARM might not be the best choice. But if an adjustable-rate loan works for your financial situation, you could have a much better shot at affording a home in today’s market.

Adjustable-rate mortgage trends over time

Adjustable-rate mortgages were hugely popular prior to 2008, at one point making up over a third of the total mortgage market. However, they were also riskier for borrowers.

Before the housing crash, ARM loans didn’t have the same protections they do now. As a result, homeowners largely avoided them over the last decade. Between 2008 and 2022, adjustable-rate loans never made up more than 10% of the mortgage market.

It’s no coincidence the share of adjustable-rate mortgages tends to move in accordance with average mortgage rates. As you read above, ARM rates are consistently lower than fixed rates on average. And as fixed mortgage rates rise, adjustable-rate loans tend to grow in popularity.

That’s exactly what we’ve seen in 2022 so far.

Adjustable-rate mortgages are less risky now

Adjustable-rate mortgages used to be far riskier than they are today. Prior to 2008, the initial fixed-rate period on an ARM (assuming you had one) was most likely brief and was the only time you were shielded from the full effects of rising interest rates. But, that has changed.

Today, the initial fixed-rate period on an ARM can last up to 10 years. When that period expires, there are caps that limit how much your rate can increase over time to help ensure you can still afford the loan, even if rates in general are rising.

Of course, the reason ARMs have lower rates is that you’re taking on some of the risk when rates spike. But borrowers are much better protected from that risk than they once were.

ARM rate caps offer protection

Each lender sets its own terms and conditions for adjustable-rate mortgages, so you’ll have to check your loan agreement for specifics. But ARMs today commonly offer three types of rate caps that protect borrowers from unreasonable rate hikes. Most ARMs have:

rate caps
End of fixed-rate periodA cap on how much your rate can increase at the end of the fixed-rate period. No matter how high interest rates have risen, it can’t exceed the cap.
Annual adjustmentsAnother cap on subsequent annual adjustments, meaning your rate can only increase by a certain amount each year.
LifetimeA third cap on how high your rate can go over the entire life of your mortgage. This protects homeowners from seeing their rates rise astronomically if the market takes a dramatic upswing.

Of course, you still have some exposure to higher interest rates – but these protections help ensure borrowers will still be able to afford their home loans, even if rates rise.

In fact, borrowers using ARM loans often must qualify based on their fully indexed rate. That means the lender will verify you’d be able to make payments even if your ARM rate was to meet its maximum cap. This rule helps ensure homeowners won’t default on their loans if rates rise sharply.

Is an adjustable-rate mortgage a good idea in 2022?

If you’re buying your forever home, there’s still real value in a fixed-rate mortgage loan. You’ll have a guaranteed rate and payment for the long haul, offering more security in your budget. And if rates fall, there’s always the option to refinance.

On the other hand, if you’re sure you’ll move within five to 10 years – within an ARM’s fixed-rate period – you should explore adjustable-rate mortgages.

After all, why pay more to lock in a rate for 30 years, when you can pay less to lock it for the number of years you’ll live in the home? For many, that’s a no-brainer.
