What To Do When You Have An Adjustable Rate Mortgage And Rates Go Up


After years of renting, buying your first home is an exciting milestone. The keys in your hand, the sense of permanence, and the pride of ownership are all unforgettable. But when the celebration is followed by rising mortgage payments due to an adjustable-rate mortgage (ARM), things can change in a hurry.

Good Times And Bad Times

Many buyers choose ARMs for their initially low interest rates, especially when fixed-rate options seem unaffordable. But when those rates adjust upward—as they often do in a volatile market—you can find yourself paying hundreds or even thousands more per month. If you’re in this position, here’s what to know and what you can do next.

Understand The Terms Of Your ARM

Before you panic, take a deep breath and review your mortgage documents. Most ARMs have an initial fixed-rate period (commonly 3, 5, 7, or 10 years) followed by an adjustment schedule (e.g., annually after the fixed period). They normally also have caps that limit how much your interest rate can increase at each adjustment and over the life of the loan. With these hard numbers in hand you can make a properly informed decision on how to proceed.

Look At The Hard Numbers

If your rate has already adjusted, compare your current rate to the cap. You might still have room before it hits its ceiling, or you might be close to maxed out. Understanding where you are in that arc helps you assess your urgency and your options.

Assess Your Monthly Budget

Next, look at how much your mortgage payment has increased and re-evaluate your monthly expenses. Can you cut discretionary spending (streaming services, dining out, vacations) to absorb the difference? This won’t be a long-term solution if rates keep rising, but it can buy you time. Also consider if your income has grown since you bought your home. Sometimes a promotion or second income source can help offset the spike.

Consider Refinancing

If your credit score and income are strong, changing to a fixed-rate mortgage may be the simplest solution. This locks in a fixed payment and shields you from future hikes. Even if current fixed rates are higher than your original ARM rate, locking in now can prevent escalation down the road. Keep in mind refinancing often has closing costs from 2–5% of the loan amount. Run the numbers to see if the long-term savings justify the upfront cost.

Explore Loan Modification

If refinancing isn’t possible—perhaps due to lower income or a dip in your home’s value—talk to your lender immediately. In some cases, they may be willing to modify your loan terms, especially if you’ve been making payments consistently.

Explore Assistance Programs

Some state or federal programs may also offer mortgage relief assistance, especially in times of widespread economic difficulty. These won’t apply to everyone, but they’re worth exploring if you’re at risk of falling behind.

Rent Out Space Or Generate Supplemental Income

If your home has an extra room, basement, or separate unit, consider renting it out. Platforms like Airbnb or longer-term leases can provide the cash flow to help cover your rising mortgage costs. Other options include side gigs, freelancing, or remote part-time work. These might feel like short-term fixes, but they can make a difference in weathering rate adjustments.

Selling May Be A Last Resort—But Not A Failure

If payments become unmanageable and no other options work, selling your home may be necessary. This isn’t failure—it’s financial self-preservation. If your home has appreciated, you might walk away with a profit and be in a better position to buy again later with a fixed-rate loan and more experience. It’s better to sell on your terms than face foreclosure down the line.

Be Proactive, Not Paralyzed

Rising payments on an ARM can feel like the rug being pulled out from under you, but you’re not helpless. Understand your mortgage terms, evaluate your options, and stay in contact with your lender, and you’ll be able to make the best decisions that protects your financial future. The key is to act early; the sooner you respond, the more choices you’ll have.
