In today’s housing market, where fixed mortgage rates have hovered around 6–7% for much of the past two years, many homebuyers are exploring creative ways to make monthly payments more manageable. One strategy that has returned to the conversation are adjustable rate mortgages, commonly known as an ARM’s.
Some headlines suggest adjustable rate mortgages are making a comeback reminiscent of the period before the 2008 housing crash. But is that actually true? If adjustable rate mortgages are increasing, does that create new risks for the housing market?
Let’s break down what ARMs are, how common they are today, and whether they represent a real threat to housing stability.
What Are Adjustable Rate Mortgages?
An adjustable rate mortgage (ARM) is a home loan where the interest rate is fixed for an initial period and then adjusts periodically based on market conditions.
Common examples include:
- 5/1 ARM: Fixed rate for five years, then adjusts annually
- 7/1 ARM: Fixed for seven years, then adjusts annually
- 10/1 ARM: Fixed for ten years before adjustments begin
During the initial fixed period, the interest rate is typically lower than a traditional 30-year fixed mortgage. For example, recent market data shows many 5/1 ARMs priced slightly below comparable fixed-rate loans, helping buyers reduce their early monthly payments.
Once the fixed period ends, however, the interest rate can move up or down depending on broader interest-rate trends.
Are Adjustable Rate Mortgages Increasing
The short answer: Yes—but only modestly.
As mortgage rates climbed above 6% in recent years, more buyers began exploring adjustable rate mortgages as an affordability strategy. In 2025, adjustable rate mortgages accounted for roughly 12.9% of mortgage applications, the highest share since 2008.
However, context matters.
Even with that increase, ARMs still represent a small portion of the overall mortgage market. Most U.S. homeowners still use traditional fixed-rate loans. In fact, around 92% of outstanding mortgages are fixed-rate loans, leaving only a small share with adjustable mortgage rates.
Looking at the broader mortgage landscape, the share of adjustable rate mortgages in early 2025 was around 7% of mortgage applications, which falls within the typical range seen since the financial crisis.
In other words, while adjustable rate mortgages are becoming more popular again, the current levels are nowhere near the extreme levels seen during the housing bubble of the early 2000s.
Now you’ve decided on which mortgage it’s time to review what to expect when in escrow and about closing costs.
Why Buyers Are Choosing ARMs Today
Today’s housing market has two big challenges: high home prices and higher mortgage rates. Adjustable rate mortgages offer a potential solution for some buyers.
Here are a few reasons why buyers use them:
1. Lower Initial Payments
Adjustable rate mortgages typically offer a lower introductory rate compared with a 30-year fixed mortgage. Even a small difference—say half a percentage point—can reduce monthly payments significantly.
For buyers stretching their purchasing power in expensive markets, that difference can make a home affordable.
2. Short-Term Ownership Plans
Many buyers don’t expect to stay in their homes for 30 years. If someone plans to move within five to seven years, a 5/1 or 7/1 ARM may provide lower payments during the entire time they own the home.
3. Expectation of Lower Future Rates
Some borrowers believe interest rates may fall in the future. If that happens, they may refinance before the adjustable portion of the mortgage kicks in.
4. Higher-Income Borrowers Using Strategic Financing
Interestingly, adjustable rate mortgages are particularly common among higher-priced homes and jumbo loans, where buyers often use them as part of a broader financial strategy rather than as a necessity.
Are Adjustable Rate Mortgages Risky?
Adjustable-rate mortgages do carry risks—but they are very different from the risky loan structures that existed before the 2008 financial crisis.
The Risk to Individual Borrowers
The biggest risk is simple: payments can increase.
If interest rates rise significantly after the fixed period ends, monthly payments may jump. This can create financial stress for homeowners who stretched their budgets.
However, modern ARMs include several safeguards:
- Rate adjustment caps that limit how much payments can increase
- Required income verification
- Stress testing to ensure borrowers can afford potential payment increases
These protections were largely absent in the pre-2008 era.
The Risk to the Housing Market
During the housing bubble, adjustable rate mortgages were used in combination with risky loan types like interest-only mortgages and option ARMs. When teaser rates expired, payments surged and many homeowners defaulted.
Today’s mortgage market looks very different.
Most borrowers are fully documented, have stronger credit profiles, and qualify under stricter underwriting rules. Additionally, the overall share of adjustable rate mortgages is far smaller than it was before the financial crisis.
Because of these factors, most economists believe the current rise in ARMs does not pose systemic risk to the housing market.
Are Lending Standards Loosening?
Another common concern is whether mortgage lenders are relaxing standards again.
So far, the evidence suggests the opposite.
Since the financial crisis, mortgage underwriting has remained significantly tighter. Borrowers generally need:
- Verified income
- Stronger credit scores
- Lower debt-to-income ratios
- Meaningful down payments
Additionally, many ARM borrowers today are underwritten at the fully indexed rate, meaning lenders evaluate whether they can afford the potential future payment—not just the initial teaser rate.
This dramatically reduces the likelihood of widespread payment shocks across the market.
The Bottom Line
Adjustable rate mortgages are becoming more common again, but the data suggests this is more of a cyclical response to higher interest rates than a repeat of the pre-2008 lending boom.
Yes, ARM applications have reached their highest level since the Great Recession. But they still represent a relatively small share of the mortgage market, and today’s loan products come with stronger protections and stricter underwriting.
For the right borrower, an ARM can be a smart financial tool—especially for buyers planning to move within a few years or expecting to refinance if rates fall.
But like any financial product, they require careful planning and a clear understanding of future risks.
In today’s housing market, adjustable rate mortgages are not inherently dangerous—they are simply another financing strategy buyers can use to navigate a higher-rate environment.
The key is understanding how they work and making sure the loan fits both your financial plan and your long-term housing goals.
