Is an ARM the Right Option for Your Needs?

ARM loans for new home purchase

If you’re focused on obtaining the lowest possible interest rate or payment during the home financing process, an adjustable-rate mortgage (ARM) may be your answer. Lenders generally charge lower initial rates for ARMs than fixed-rate mortgages, which equates to smaller monthly payments.

How an ARM loan works

ARMs can be used for home purchases or mortgage refinances, including cash-out refinances. They were designed to offer rates that fluctuate after a certain amount of time, creating significant upfront savings. Yet there is also the potential for higher payments later in the loan term.

When to use an ARM

ARMs are attractive loan programs for the right borrower. The following situations are key reasons to consider one of the many ARM options.

You’ll be on the move again soon

Looking to relocate? Maybe you’re buying something small to gain equity that can be used toward a larger home purchase? If this sounds familiar, an ARM may be for you. You’ll never be hit with rate increases because you’ll be moving before the adjustable-rate period begins.

If you’re in search of your forever home, though, you may want to avoid an ARM. If rates go up after your introductory period ends, it will likely require a mortgage refinance to lock you into more stable payments.

Market rates are on the rise

Rising interest rates on fixed loans are the most significant reason ARMs become attractive. Since ARMs offer a lower initial rate, they’re able to save buyers hundreds or even thousands of dollars on their purchase.

While the Federal Reserve (Fed) is not expected to raise rates in the short term, we could be looking at a few increases toward the end of 2019. Of course, the Fed does not directly influence mortgage rates, but it does have a significant impact on them. It’s something to pay attention to if you’re planning to buy a home or refinance a mortgage this year.

You like to purchase, renovate, and resell properties

House flippers may benefit from an adjustable-rate mortgage’s primary benefits, especially if they’re certain they can be in and out before that intro period ends. The true advantage is there is less interest to pay, so more goes toward principal, and that equates to faster equity growth — an added bonus when it comes time to sell!

Keep in mind home rehab and construction loans also exist, so be sure to seek guidance from a lender before choosing one loan over the other.

Down payments

Down payments for ARMs are usually the same as fixed-rate loans, but there are loan types that allow for lower down payments (FHA or VA loans). In most cases, expect to have a minimum of 5% down, though 20% is preferred because private mortgage insurance (PMI) is often required on loans with less than a 20% down payment.

Types of ARMs

5/1 ARMs

The most popular adjustable-rate mortgage is the 5/1 ARM. The 5/1 ARM’s introductory rate lasts for five years, hence the name 5/1. The remaining 25 years of the loan will adjust on an annual basis, which is the “one” in 5/1.

7/1 ARMs

Another option is to opt for a seven-year introductory rate that increases annually for the remaining 23 years. Its rate is a little higher than its 5/1 counterpart but is worth considering if you plan on moving within six years.

10/1 ARMs

If you expect to own for ten years or less, a 10/1 ARM may be for you. They come with a higher rate than the 5/1 and 7/1 but are still competitive when compared with a traditional 30-year fixed-rate mortgage.

3/1 ARMs

This is the riskiest of all ARM options because the rate can increase sooner than later (after three years is up). You’ll want to be very sure of your near future plans before choosing this loan option.

How an ARM adjusts

The interest rate on an ARM is made up of two parts: the index and the margin. The index is a measure of interest rates, and the margin is an extra amount added by the lender. Some lenders base the margin amount on your credit record — the better your credit, the lower the margin, and the less interest you will pay on your mortgage.

Your payment goes up when the index of interest rates increases, though your payment may go down when it declines. Keep in mind that this is not true for all ARMs, so be sure to check with your lender. Some ARMs set a cap on how high your interest rate can go, and they can also limit how low your interest rate can go.

The most common indexes lenders use are Constant Maturity Treasury (CMT) securities, the Cost of Funds Index (COFI), and the London Interbank Offered Rate (LIBOR).

Interest rate caps

ARM caps are in place to limit interest rate movement as to not shock borrowers when their ARMs adjust.

Initial adjustment cap

This cap says how much the interest rate can adjust after the fixed-rate period expires.

Subsequent or periodic cap

This cap tells you how often your rate can change during each following period. It’s most commonly set at 2%, meaning the new rate cannot be more than 2% of the previous rate.

Lifetime or overall cap

This tells you how much the interest rate can increase, in total, over the life of the loan. All adjustable-rate mortgages have an overall cap.

Key takeaways

Lenders must provide written disclosures on each type of ARM loan you are interested in. The information must include the terms and conditions for each loan, including details about the index and margin, how your rate will be calculated, how often your rate can change, limits on changes (or caps), and an example of how high your monthly payment might go.
