When shopping for a home loan, you’ll likely encounter two main types: fixed-rate loans and adjustable-rate mortgages (ARMs). One popular option is the 5/1 ARM, which may benefit specific homebuyers looking for initial savings.
Let’s explore everything you need to know about a 5/1 ARM loan, from how it works to the pros and cons to consider.
What Is a 5/1 ARM Loan?
A 5/1 ARM (Adjustable-Rate Mortgage) is a home loan whose interest rate stays fixed for the first 5 years and then becomes adjustable for the remainder of the term. The '5' represents the 5-year period during which the interest rate is fixed, while the '1' means the rate can adjust once a year after this period. This structure can allow for potential savings initially but also introduces future rate variability.
This type of loan can be appealing because the starting interest rate is often lower than what you’d find with a fixed-rate mortgage. However, once the fixed period ends, your rate and monthly payments may increase or decrease depending on market rates.
How Does a 5/1 ARM Work?
Thanks to the fixed interest rate, your monthly payment remains the same during the first five years. After this period, the loan switches to an adjustable rate, which can go up or down annually. The new rate is determined by adding a set margin (specified in your mortgage documents) to an index rate like the Secured Overnight Financing Rate (SOFR) or Treasury rate.
5/1 ARMs usually come with rate caps to protect borrowers, limiting how much your interest rate can change. For example, A 5/1 ARM with 2/2/5 caps sets limits on rate increases over time, as follows:
- Initial cap: The rate can’t increase more than 2% at the first adjustment.
- Subsequent caps: The rate can’t exceed 2% in each adjustment period.
- Lifetime cap: The rate increase is capped at 5% over the initial rate for the life of the loan.
5/1 ARM Loan Example
Let’s say you take a $250,000 5/1 ARM loan with a starting rate of 7%, while a comparable 30-year fixed-rate loan has a 7.5% rate. With the ARM, you might save around $85 monthly during the initial 5 years. However, your monthly payments could increase significantly if the rate rises after the fixed period.
Pros of a 5/1 ARM Loan
Lower Initial Rate:
The fixed rate during the first 5 years is typically lower than a comparable fixed-rate loan, potentially saving you money upfront.
Potential for Lower Total Interest Cost.
If you put your initial savings directly toward the loan’s principal, you can reduce your overall loan balance, resulting in less interest over time.
Good for Short-Term Homeowners:
If you plan to sell the home or refinance before the rate adjusts, you might avoid the potential rate hikes with the adjustable period.
Cons of a 5/1 ARM Loan
Potential for Rising Payments:
Once the fixed period ends, your interest rate may increase, potentially leading to much higher payments than you initially expected.
Possibility of Higher Total Interest:
If rates increase after the fixed period ends, you may pay more interest over time.
Refinancing Costs:
If you plan to refinance fixed-rate loan, remember that refinancing typically comes with closing costs, ranging from 2–6% of the loan amount.
Is a 5/1 ARM Right for You?
A 5/1 ARM might be a smart choice if you’re looking for lower initial payments and plan to sell or refinance before the rate adjusts. However, if you intend to stay in your home longer, a fixed-rate mortgage might offer greater stability and predictability in your monthly payments.
Common Questions About 5/1 ARMs
Why is it called a "hybrid"?
A 5/1 ARM is called a hybrid mortgage because it combines a fixed-rate period with an adjustable rate, giving it characteristics of both fixed-rate and adjustable-rate loans.
What happens if rates rise dramatically?
If rates increase significantly, refinancing to a fixed-rate mortgage can offer more stability, potentially reducing future rate increases.
What’s the difference between a 5/1 and 7/1 ARM?
A 5/1 ARM has a 5-year fixed-rate period, while a 7/1 ARM has a 7-year fixed-rate period. Both adjust annually after their respective fixed-rate periods end.
The Bottom Line
A 5/1 ARM may offer short-term savings and flexibility, especially for buyers planning to move or refinance soon. However, because rates can rise after a fixed period, carefully consider if this aligns with your long-term goals.
