An adjustable-rate mortgage, or ARM, can seem like an enticing offer, as they often offer initially lower rates than the more standard fixed-rate mortgage. But later on, the rate is subject to change based on wherever mortgage rates head — and that certainly can be upward, leaving borrowers with higher payments as a result.
Still, more buyers are increasingly willing to take that gamble, given the current housing market that has left some “desperate for affordable monthly payments when home prices are up more than 50% since 2019 and are near all-time highs,” said The Wall Street Journal. Many people are accepting ARMs in the hopes that “mortgage rates will fall in the coming years, enabling them to refinance before the fixed terms of their ARM loans expire.” But there is no guarantee that will happen, nor is that the only risk of this type of mortgage loan.
How do adjustable-rate mortgages work?
An ARM has two periods: a fixed period and an adjustment period. During the fixed period, which usually lasts anywhere from three to 10 years, the interest rate on the loan does not change. After that, the adjustment period begins, when the rate can start changing, going either up or down based on market conditions.

These rate changes during the adjustment period typically occur every six or 12 months. When those intervals hit, “if there’s a drop in the benchmark index your lender selects when your ARM resets, your rate will go down,” whereas “if there’s an increase in that benchmark, that rate will go up,” said CNBC Select.
What are the risks of an ARM?
When the interest rate on your mortgage is changing periodically, it introduces uncertainty into your financial situation. There is always the chance that your rate will go up, which in turn will increase your monthly payments. Managing these swings requires some budgeting flexibility.
If, for whatever reason, you cannot afford the higher payments when they happen, “you could default, harm your credit and ultimately face foreclosure,” said Bankrate. Even if you can swing the steeper payments, you could “end up paying more overall for an ARM than if you’d initially taken out a fixed-rate mortgage instead,” even if the initial rate was lower in comparison, said Rocket Mortgage.
Plus, securing an ARM in the first place is potentially “more difficult” than a fixed-rate mortgage, as “you’ll need a higher down payment of at least 5%, versus 3% for a conventional fixed-rate loan,” said Bankrate.
When can an adjustable-rate mortgage make sense?
Despite the risks, an ARM can be a “smart financial choice if you are planning to keep the loan for a limited period of time and will be able to handle any rate increases in the meantime,” said Investopedia. For instance, if you “expect rates to drop before your ARM rate resets, taking out an ARM now, and then refinancing to a lower rate at the right time, could save you a considerable sum of money,” said Bankrate.
Additionally, said Bankrate, for those “planning to sell before the fixed period is up,” such as buyers who are purchasing their starter home and soon plan to upgrade, an ARM “can save you a bundle on interest.”
