What Is an Adjustable-Rate Mortgage?

ARMs are home loans whose rates can vary over the life of the loan. Unlike a fixed-rate mortgage, which carries the same interest rate over the entirety of the loan term, ARMs start with a rate that’s fixed for a short period, say five years, and then adjust.

For example, a 5/1 ARM will have the same rate for the first five years, then can adjust each year after that—meaning the rate might go up or down, based on the market.

How Does an Adjustable-Rate Mortgage Work?

ARMs are always tied to some well-known benchmark—an interest rate that’s published widely and easy to follow—and reset according to a schedule your lender will tell you in advance. But since there’s no way of knowing what the economy or financial markets will be doing in several years, they can be a much riskier way to finance a home than a fixed-rate mortgage.

Pros and Cons of an Adjustable-Rate Mortgage

An ARM isn’t for everyone. You need to take the time to consider the pros and cons before choosing this option.

Pros of an Adjustable-Rate Mortgage

• Lower initial interest rates. ARMs often, though not always, carry a lower initial interest rate than fixed-rate mortgages do. This can make your mortgage payment more affordable, at least in the short term.
• Payment caps. While your interest rate may go up, ARMs have payment caps, which limit how much the rate can go up with each adjustment and how many times a lender can raise it.
• More savings in the first few years. An ARM may still be a good option for you, particularly if you don’t think you’ll stay in your home for a long time. Some ARMs have initial rates that last five years, but others can be as long as seven or 10 years. If you plan to move before then, it might make more financial sense to go with an ARM instead of a fixed-rate mortgage.

Cons of an Adjustable-Rate Mortgage

• Potentially higher rates. The risks that accompany ARMs are no longer just hypothetical. The Federal Reserve, which sets interest rates throughout the economy, has been raising interest rates aggressively and plans to keep them elevated for some time. This means that any ARM that you take out now may have a higher, and possibly substantially higher, rate when it resets in a few years.
• Little advantage when rates are low. ARMs don’t make as much sense when interest rates are historically low. There was essentially no cost savings in opting for an ARM during the past few years when all interest rates were at rock-bottom levels—so it always pays to shop around.
• May be difficult to understand. ARMs have complicated structures, and there are many types, which can make things confusing. If you don’t take the time to understand how they work, it could end up costing you more than you expect.

Types of ARMs

There are three types of adjustable-rate mortgages:

• Hybrid. The traditional type of ARM. Examples of hybrid ARMs include 5/1 or 7/6 ARMs. The interest rate is fixed for a set number of years (indicated by the first number) and then adjusts at regular intervals (indicated by the second number). For example, a 5/1 ARM means that the rate will stay the same for the first five years and then adjust every year after that. A 7/6 ARM rate stays the same for the first seven years then adjusts every six months.
• Interest-only. An interest-only (I-O) mortgage means you’ll only pay interest for a fixed number of years before you start paying down the principal balance—unlike a conventional fixed-rate mortgage where you pay a portion of the principal and interest every month. With an I-O home loan, your monthly payments start off small and then increase over time as you eventually start to pay down the principal balance. Most I-O periods last between three and 10 years.
• Payment option. This type of ARM allows you to pay back your loan in different ways. For instance, you can choose to pay traditionally (principal and interest), interest only or the minimum payment.

ARM Loan Requirements

While ARM loan requirements vary by lender, here’s what you generally need to qualify for one.

Credit Score

Aim for a credit score of at least 620. Many of the best mortgage lenders won’t offer ARMs to borrowers with a score lower than 620.

Debt-to-Income Ratio

ARM lenders generally require a debt-to-income (DTI) ratio of less than 50%. That means your total monthly debt should be less than 50% of your monthly income.

Down Payment

You’ll typically need a down payment of at least 3% to 5% for a conventional ARM loan. Don’t forget that a down payment of less than 20% will require you to pay private mortgage insurance (PMI).

FHA ARM loans only require a 3.5% down payment, but paying that amount means you’ll have to pay mortgage insurance premiums for the life of the loan.

Adjustable-Rate Mortgage vs. Fixed

Fixed-rate mortgages are often considered a wiser option for most borrowers. Being able to lock in a low interest rate for 30 years—but still have the option to refinance as you want, if conditions change—often makes the most financial sense. Not to mention it’s predictable, so you know exactly what your rate is going to be over the course of the loan term.

But not everyone expects to stay in their home for years and years. You may be buying a starter home with the intention of building some equity before moving up to a “forever home.” In that case, if an ARM has a lower interest rate, you may be able to direct more of your money into that nest egg.

Alternatively, an ARM with a lower rate than a fixed-rate mortgage may simply be more affordable for you. As long as you’re comfortable with the idea of selling your home or otherwise moving on before the ARM’s initial rates reset—or taking the chance that you’ll be able to afford the new, higher payments—that may also be a reasonable choice.

How To Get the Best ARM Rate

If you’re not sure whether an ARM or a fixed-rate mortgage makes more sense for you, you should research lenders who offer both. A mortgage professional like a broker may also be able to help you weigh your options and secure a better rate.

Can You Refinance an Adjustable-Rate Mortgage?

It’s possible to refinance an existing adjustable-rate mortgage into a new ARM or fixed-rate mortgage. You may consider an adjustable-rate refinance when you can get a better interest rate and benefit from a shorter repayment period.

Turning an existing adjustable-rate mortgage into a fixed interest rate mortgage is the better option when you want the same interest rate and monthly payment for the life of your loan. It may also be in your best interest to refinance into a fixed-rate mortgage before your ARM’s fixed-rate introductory period ends.

Is an Adjustable-Rate Mortgage a Good Idea?

Adjustable-rate mortgages can have lower interest rates during the introductory period than fixed-rate loans. It’s also possible for rates to fall in the future, which may result in you paying less interest over the life of the loan than if you had taken out a fixed-rate mortgage from the start.

You should also consider an ARM if you’re comfortable with a short repayment period, such as when you’re planning on paying off your mortgage early.

However, this may not be the best loan type for borrowers that need as long as 30 years to pay back their mortgage as interest rates can fluctuate widely over the life of the loan. Consider a fixed-rate refinance to lock in the same rate and monthly payment for the entire repayment period. This has the added bonus of allowing you to easily estimate your total interest costs.
