Adjustable-Rate Mortgages Are Making a Comeback: What Charlotte Homebuyers Need to Know
For years, adjustable-rate mortgages, or ARMs, have been a financing option that many homebuyers rarely considered. But as mortgage rates climb closer to 7% in 2026, more buyers are starting to take another look.
According to recent data from the Mortgage Bankers Association, adjustable-rate mortgages accounted for nearly 10% of mortgage applications in the latest reporting week. At the same time, the average 30-year fixed mortgage rate reached its highest weekly average since January 2025.
For buyers searching for homes in Charlotte, Concord, Kannapolis, Harrisburg, and throughout the greater Charlotte area, this raises an important question:
Could an adjustable-rate mortgage make sense in today's market?
The answer depends heavily on your financial situation, how long you expect to own the home, and how comfortable you would be with the possibility of a changing payment in the future.
Why Are More Buyers Considering ARMs?
The biggest reason is simple: affordability.
When fixed mortgage rates rise, even a small difference in interest rate can significantly affect a buyer's monthly payment and purchasing power.
Homes.com reported that the 30-year fixed mortgage rate reached 7.17%, while a 7/6 adjustable-rate mortgage was being offered at 6.72% at the time of its September 23 report—a difference of about 0.45 percentage points.
That lower initial rate can make a meaningful difference for a buyer who is trying to keep their monthly payment within a specific budget.
It is also happening at a time when buyers have more homes to choose from. Homes.com reported that the number of homes for sale nationwide increased 5.4% in August compared with August 2025. Yet higher borrowing costs continue to limit how many buyers can comfortably enter the market.
In other words, buyers may have more choices—but financing those homes is still a major hurdle.
What Exactly 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 adjust based on the terms of the loan.
You'll often see ARMs written as something like:
7/6 ARM
The first number represents the number of years the initial interest rate is fixed.
The second number represents how frequently the interest rate can adjust after that initial period.
So, a 7/6 ARM generally means:
Your initial interest rate is fixed for seven years.
After those seven years, the rate can adjust every six months.
The future rate is determined according to the terms of the loan, including its underlying index and margin.
Caps generally limit how much the rate can increase at each adjustment and over the life of the loan.
The important distinction is that the initial rate is not necessarily the rate you will have for the entire mortgage.
That's what makes an ARM different from a traditional fixed-rate mortgage.
Why Would Someone Choose an ARM?
There are several reasons a buyer might consider one.
1. A lower initial interest rate
The most obvious potential benefit is a lower starting rate.
In the Homes.com example, the 7/6 ARM rate was about 0.45 percentage points below the 30-year fixed rate being tracked at the time.
For some buyers, that could mean a lower initial monthly payment.
2. More purchasing power
A lower interest rate can allow a buyer to qualify for a larger loan amount while staying within a lender's qualifying parameters.
However, buyers should be careful not to interpret that as meaning they should automatically buy more house.
The more important question is:
What payment can you comfortably afford—not simply what payment can you qualify for?
3. You may not plan to own the home for decades
An ARM may be worth discussing with a lender if you know your circumstances could change before the introductory period ends.
For example, someone purchasing a starter home who expects to move within several years may want to compare an ARM with a fixed-rate mortgage.
But this should never be based solely on the assumption that you'll definitely sell before the rate changes. Life doesn't always follow the original plan.
The Biggest Risk: What Happens When the Rate Adjusts?
This is the part buyers need to understand before choosing an ARM.
The lower initial rate is not guaranteed forever.
Once the introductory period ends, the interest rate can adjust according to the loan's terms. If market rates are higher at that point, your monthly payment could increase.
For example, imagine you purchase a home with a 7/6 ARM because the initial rate is lower than the available fixed-rate options.
Seven years later, you still own the home.
If interest rates have increased, your mortgage payment could rise when the loan adjusts.
That's why looking only at the initial payment doesn't tell the entire story.
Before choosing an ARM, buyers should ask their lender to show them what their payment could look like under different future interest-rate scenarios.
What Are ARM Caps?
One important feature of adjustable-rate mortgages is the presence of interest-rate caps.
These caps can limit how much the interest rate can increase at various points during the loan.
There can be different types of caps, including:
Initial adjustment cap: Limits the increase when the loan first adjusts.
Periodic adjustment cap: Limits how much the rate can change at subsequent adjustments.
Lifetime cap: Limits how high the interest rate can rise over the life of the loan.
The exact caps vary by loan.
That's why two ARMs can look similar on the surface but have very different terms.
Don't compare ARMs based solely on the initial interest rate.
Ask your lender to walk you through the complete loan structure.
ARM vs. Fixed-Rate Mortgage: What Should Buyers Compare?
There isn't one mortgage that makes sense for every buyer.
Instead, compare the two loans based on the factors that actually affect your finances.
The key is to look beyond the first few years.
If you're considering an ARM, ask your lender:
What would my payment be if rates are higher when my loan adjusts?
That number may be much more important than the initial payment.
What Does This Mean for Charlotte and Concord Homebuyers?
For buyers in the Charlotte region, higher mortgage rates are creating an interesting dynamic.
There are more homes available than there were a year ago nationally, but higher borrowing costs are still limiting demand. Homes.com reported a 5.4% year-over-year increase in U.S. for-sale inventory in August, while the National Association of Realtors reported that pending home sales declined 4.7% year over year in August.
For local buyers, that can mean more opportunities to shop and negotiate while financing remains one of the biggest pieces of the equation.
In communities such as Concord, Kannapolis, Harrisburg, Huntersville, and Charlotte, buyers may encounter everything from resale homes to new construction with builder incentives.
That makes it especially important to compare the entire financing package.
For example, a buyer might encounter:
A traditional fixed-rate mortgage
An ARM with a lower introductory rate
A seller offering closing-cost assistance
A builder offering a temporary or permanent rate buydown
A lender offering credits toward closing costs
A combination of incentives
The lowest advertised rate isn't automatically the lowest-cost option.
Don't Forget About Seller and Builder Incentives
Mortgage financing isn't the only way to address affordability.
In today's market, buyers may also be able to negotiate seller concessions or take advantage of incentives offered by builders.
A seller credit could potentially help with eligible closing costs or a rate buydown, depending on the loan program and transaction.
New-construction builders may also offer financing incentives through preferred lenders.
This is particularly relevant around the Charlotte metro, where new construction remains an important part of the housing market.
The right comparison is not simply:
"Which house has the lowest interest rate?"
It is:
"Which combination of price, rate, incentives, loan terms and monthly payment makes the most sense for my situation?"
Should You Assume You'll Refinance Later?
This is one of the biggest things I would caution buyers against.
You may hear:
"Just take the ARM now and refinance when rates come down."
Maybe that happens.
But there is no guarantee.
Mortgage rates could be higher when you're ready to refinance. Your home value could change. Your financial situation could change. Or you may simply decide that refinancing doesn't make financial sense at that time.
If you're considering an ARM, the mortgage should make sense based on the terms you are actually agreeing to—not solely on the hope that you'll refinance later.
Questions to Ask Before Choosing an ARM
If you're considering an adjustable-rate mortgage, talk with your lender about these questions:
What is my initial interest rate?
How long is that rate fixed?
When can the rate first adjust?
How often can it adjust after that?
What index and margin determine future adjustments?
What are the initial, periodic and lifetime rate caps?
What would my payment be at the maximum possible rate?
Are there any prepayment penalties?
What are the closing costs and fees?
How does this compare with a fixed-rate loan over the time I realistically expect to own the home?
Getting answers to these questions can make the difference between understanding your loan and simply choosing the rate that looks best on a mortgage worksheet.
The Bottom Line for 2026 Homebuyers
Adjustable-rate mortgages are becoming more popular again as mortgage rates approach 7%.
The latest Homes.com reporting shows that nearly 10% of mortgage applications are now ARMs, while fixed mortgage rates have climbed to their highest weekly average since January 2025.
That doesn't mean an ARM is the right choice for every buyer.
It means buyers have another financing option worth understanding.
If you're purchasing a home in Concord, Charlotte, Kannapolis, Harrisburg, or the surrounding Cabarrus County area, don't make your decision based solely on today's advertised interest rate.
Look at the entire picture: your monthly payment, how long you expect to own the home, your financial cushion, the potential future payment, available seller or builder incentives, and the terms of the loan.
The goal isn't simply to find the lowest rate.
It's to choose a mortgage that fits your financial situation today while understanding what could happen tomorrow.
If you're thinking about buying a home in the Charlotte or Concord area, having a Realtor and lender who can help you compare the different financing scenarios can make the process much easier.
