Are Adjustable-Rate Mortgages Worth It in 2026? What North Carolina Home Buyers Should Know
For the past few years, home buyers have had to get creative when it comes to affordability.
Home prices remain elevated in many markets, and mortgage rates have climbed significantly from the historically low rates buyers became accustomed to during the pandemic.
Now that 30-year fixed mortgage rates have moved above 7%, another mortgage option is getting more attention:
The adjustable-rate mortgage, or ARM.
According to a recent Realtor.com analysis, the average 30-year fixed mortgage rate reached 7.30% in the final week of September 2026, while the average 5/1 adjustable-rate mortgage was 6.47%. On a $400,000 home with 20% down, that difference translated to approximately $178 less per month in principal and interest with the ARM.
That kind of monthly savings can be significant.
But there is an important question every buyer needs to ask:
Is saving money today worth taking on the possibility of a higher payment later?
The answer isn't the same for everyone.
What Is an Adjustable-Rate Mortgage?
An adjustable-rate mortgage is a home loan where the interest rate is fixed for an initial period and then can change based on market conditions.
For example, a 5/1 ARM typically has a fixed interest rate for the first five years. After that, the rate can adjust once per year.
A 5/6 ARM also has a five-year initial fixed period, but the rate can adjust every six months after that.
The appeal is straightforward:
You typically receive a lower initial interest rate than you would with a comparable 30-year fixed mortgage.
The trade-off is that your interest rate—and therefore potentially your monthly payment—can increase once the fixed period ends.
That's the part buyers need to understand before deciding whether an ARM makes sense.
Why Are ARMs Becoming More Popular Again?
Mortgage rates have changed the affordability equation for buyers.
At the beginning of 2026, the average 30-year fixed mortgage rate was about 6.18%, compared with approximately 5.42% for a 5/1 ARM.
By late September, both rates had risen, but the gap between the two had actually widened to about 83 basis points.
That difference matters.
When an ARM offers a significantly lower initial rate, the buyer can potentially save hundreds of dollars per month compared with a fixed-rate mortgage.
And more buyers are starting to consider that option.
ARMs accounted for 10.3% of mortgage applications in late September 2026, up from approximately 7% at the beginning of the year. That was the highest share since October 2025.
For some buyers, the lower initial payment could be the difference between being able to purchase a home and remaining on the sidelines.
How Much Could You Save?
Let's use an example from the current market.
Imagine you are borrowing $320,000.
At a 7.30% fixed rate, the estimated principal-and-interest payment would be approximately $2,194 per month.
At a 6.47% ARM, the initial payment would be approximately $2,016 per month.
That's a difference of roughly:
$178 per month
Over five years, that adds up to more than $10,000 in lower monthly payments.
However, the ARM in this example also comes with somewhat higher upfront points and origination costs.
Even after accounting for those additional costs, Realtor.com's analysis found that the ARM borrower would have paid approximately $10,650 less in monthly payments over the first five years and would owe roughly $2,700 less on the mortgage at that point.
So there is a real financial benefit.
But that doesn't mean the ARM automatically wins.
Because eventually, the rate can change.
Here's Where the Risk Comes In
The biggest misconception about ARMs is that the interest rate simply jumps dramatically after the initial period.
That's not necessarily how today's loans work.
ARMs have caps that limit how much the interest rate can increase at each adjustment and over the life of the loan.
For example, Realtor.com looked at an illustrative 5/6 ARM with a 2/1/5 cap structure.
That means:
The rate is fixed for five years.
At the first adjustment, it can increase by no more than 2 percentage points.
Subsequent adjustments can increase by no more than 1 percentage point.
The total lifetime increase is capped at 5 percentage points.
Those caps provide some protection—but they don't eliminate the risk.
What Could Happen to Your Payment?
Using that same hypothetical example, a 6.47% ARM could potentially rise to 8.47% at its first adjustment if rates moved as high as the loan's cap allows.
The estimated principal-and-interest payment could increase from approximately:
$2,016 → $2,405 per month
And if the rate continued rising at the maximum allowed pace, the payment could eventually reach approximately $3,023 per month at the lifetime rate cap.
That's a very different monthly payment.
And it's why I would never recommend choosing an ARM based solely on the initial payment.
The more important question is:
"Could I afford this house if my payment eventually increased?"
If the answer is no, an ARM may not be the right loan for you.
What Happened With ARMs During the Housing Crisis?
If the words "adjustable-rate mortgage" immediately make you think about the 2008 housing crisis, you're not alone.
ARMs became heavily associated with the financial crisis because of the large number of risky subprime loans issued during the housing boom.
But it's important to understand that today's mainstream ARM products operate under different lending standards.
During the housing crisis, many borrowers were approved based heavily on initial low payments, while some loans had extremely risky structures.
Today, lenders generally cannot qualify borrowers solely based on a temporary introductory payment if the loan could later reset higher.
That doesn't make an ARM risk-free.
It simply means that today's ARM market is different from the one that existed before the financial crisis.
Who Might Consider an ARM?
An ARM isn't necessarily a bad mortgage.
In fact, there are situations where it could be a very useful financial tool.
1. You expect to move within the initial fixed period
If you know your career, family or lifestyle will likely take you somewhere else within five years, you may not expect to have the loan when the first adjustment occurs.
However, you should never rely on a future sale as your only exit strategy.
Life doesn't always follow the plan.
2. You expect to refinance—but can afford the payment if you don't
If mortgage rates eventually fall, refinancing could potentially allow you to move into a fixed-rate mortgage.
But refinancing isn't guaranteed.
You still have to qualify, your home's value matters, and refinancing comes with closing costs.
3. The ARM discount is substantial
The bigger the difference between the ARM and fixed rate, the more you're saving during the initial fixed period.
If the difference is only a tiny fraction of a percentage point, taking on additional interest-rate risk may not be worth it.
4. You have a strong financial cushion
An ARM is much easier to manage when you have room in your budget.
If a payment increase would completely disrupt your finances, a fixed-rate mortgage may provide a level of predictability that's worth paying for.
Who Probably Shouldn't Choose an ARM?
An ARM may not be a great fit if:
You plan to stay in the home for 10+ years.
Your budget is already stretched.
You would struggle with a significant payment increase.
You have little emergency savings.
You're counting on refinancing to make the loan affordable.
You're assuming you'll definitely sell before the rate adjusts.
The difference between the ARM and fixed rate is relatively small.
One of the biggest reasons to be cautious is that Americans are staying in their homes longer.
According to Realtor.com, the median seller tenure increased from approximately six years between 2000 and 2008 to a record 11 years in 2025.
That means the assumption that you'll definitely sell before an ARM adjusts may not be as safe as it once was.
The "I'll Just Refinance Later" Strategy
This is probably the biggest thing I would caution buyers about.
You may hear:
"I'll just get the ARM now and refinance when rates come down."
Maybe.
But nobody knows exactly when—or if—rates will fall enough to make refinancing worthwhile.
And even if rates do fall, you still have to qualify for the new mortgage.
Your income could change.
Your credit could change.
Your home's value could change.
And refinancing comes with its own costs.
Realtor.com's analysis specifically recommends that borrowers treat refinancing as a possibility rather than a guarantee.
A good rule of thumb is:
Choose an ARM only if you can handle the loan even if your future plan doesn't go exactly as expected.
If refinancing happens later and saves you money, that's a bonus—not the foundation of the plan.
What Does This Mean for Buyers in North Carolina?
For buyers here in Concord, Kannapolis, Harrisburg, Huntersville, Charlotte, Mooresville, Cornelius, Davidson, Salisbury, Lexington and surrounding communities, ARMs could become a more common part of the financing conversation as rates remain elevated.
And I think that's a good thing—as long as buyers understand what they're actually agreeing to.
A mortgage isn't simply about finding the lowest rate.
It's about finding the loan structure that fits your financial situation.
For one buyer, a 30-year fixed mortgage may be worth the higher initial payment because they want complete predictability.
For another buyer, a 5/6 ARM might provide enough savings to comfortably purchase a home they otherwise couldn't afford.
Neither choice is automatically right or wrong.
The key is understanding the full range of possible outcomes.
Questions to Ask Your Lender Before Choosing an ARM
If you're considering an adjustable-rate mortgage, don't just ask:
"What's the interest rate?"
Ask:
How long is the initial fixed period?
Five years? Seven years? Ten?
How often can the rate adjust after that?
Once a year? Every six months?
What is the initial adjustment cap?
This tells you how much the rate can increase at the first adjustment.
What is the periodic adjustment cap?
This limits increases at subsequent adjustments.
What is the lifetime cap?
This tells you the maximum possible increase over the life of the loan.
What would my payment be at the maximum possible rate?
This is one of the most important numbers to understand.
Are there prepayment penalties?
You want to understand what happens if you sell or refinance early.
How much am I paying in points and closing costs?
A lower interest rate isn't necessarily a better deal if you're paying substantially more upfront.
So, Are Adjustable-Rate Mortgages Worth It in 2026?
Sometimes.
And that's probably the most honest answer.
The current environment has made ARMs more attractive because the initial interest rate can be meaningfully lower than a 30-year fixed mortgage.
At the same time, that lower payment comes with uncertainty.
Your rate could stay relatively favorable.
It could increase.
Or it could eventually decrease.
The important thing is that you don't build your entire home-buying strategy around the assumption that rates will move in the direction you want.
Instead, look at three things:
1. How much are you saving today?
A larger rate discount provides a larger financial benefit during the initial fixed period.
2. How high could your payment go?
Understand the loan's adjustment and lifetime caps before you sign anything.
3. How long are you likely to own the home?
The longer you expect to stay, the more important the future rate risk becomes.
The Bottom Line for North Carolina Home Buyers
Mortgage rates above 7% have forced buyers to become more creative.
Adjustable-rate mortgages are one option—but they're not a magic solution to affordability.
For the right buyer, an ARM could provide meaningful savings during the first several years of homeownership.
For another buyer, the predictability of a fixed-rate mortgage may be worth paying more upfront.
There isn't a single mortgage product that's right for everyone.
If you're considering buying a home in Concord, Kannapolis, Harrisburg, Huntersville, Charlotte, Salisbury, Lexington or the surrounding North Carolina communities, talk with a qualified lender about both fixed and adjustable options and make sure you understand the best-case and worst-case scenarios.
As a Realtor, my job isn't to tell you which mortgage you should choose. That's a conversation to have with your lender.
My job is to help you understand the home you're buying, the local market you're buying in, and whether the overall purchase makes sense for your goals.
The lowest initial payment isn't always the best deal. The best mortgage is the one you can comfortably live with—not just today, but if things don't go according to plan.
