  • Adjustable-rate mortgages (ARMs) offer flexibility and potential savings.
  • ARMs feature initial lower interest rates and monthly payments.
  • Different types of ARMs exist, such as the 5/1 and 10/1, with fixed-rate periods followed by adjustable rates.
  • Benefit consumers by easing initial financial burdens and providing flexibility.

Adjustable-rate mortgages (ARM) can save you money and lower monthly payments. Unlike a fixed-rate mortgage, adjustable-rate mortgages give you more flexibility. For example, they will fall when interest rates drop, which means you will be saving money.  

With a fixed-rate mortgage, the interest rate remains constant throughout the life of the loan. Conversely, an ARM has an interest rate that can change based on money market fluctuation. 

Depending on your financial situation and the monthly payments you can afford, you can choose the type of loan that best matches your needs and adjusts to your income. If you have previous financial obligations such as a student loan, an auto loan, or a small business loan, you may benefit from an adjustable-rate mortgage that will lower your monthly expenses.

What Are Adjustable-Rate Mortgages?

When you apply for a mortgage loan, the bank offers either a fixed interest rate or an adjustable one. The fixed interest rate remains the same throughout the mortgage period or for a fixed period. Adjustable interest rates are adjusted — usually every 12 months — according to the Federal Reserve interest rate. 

Types of ARMs

There are various types of ARMs. 

Typically, an ARM begins with a fixed-rate period, after which the rate adjusts at predetermined intervals. Most ARMs start with a fixed financing rate period that varies from 3 to 10 years. 

A first-time home buyer can, for example, choose a 5/1 adjustable rate mortgage. This means the interest fixed rate will stay constant for 5 years. After the 5 years are up (years 6, 7, and so forth), the interest will adjust based on the index rate. A 10/1 adjustable rate mortgage will be fixed for 10 years and then adjustable for the remaining. 

The shorter the fixed-rate period, the better the terms you will typically get. If you opt for a 3/1 ARM, you have three years of fixed interest rate followed by flexible interest rates for the lifetime of your mortgage. As a bonus, a 3/1 mortgage will give you a lower fixed interest rate than a 5/1 or a 7/1. 

Pros and Cons of ARMs

Homebuyers who want to lower the financial burden of a mortgage can opt for an adjustable-rate mortgage. Others who want to repay the principal faster can also choose an ARM and benefit from lower rates. 

Adjustable rate mortgages adapt to the interest rates as given by the Federal Reserve. When these fall, your monthly payments will also decrease, giving your finances a significant boost. 

To make financial decisions, it is always good to weigh these benefits against your personal financial situation and long-term housing plans. Additionally, when exploring financial options, consider products like money market accounts, best personal loans, and debt consolidation loans to optimize overall financial health. 

If you plan to sell or refinance your home shortly after buying it, a longer fixed-rate period before it becomes adjustable could be helpful. Likewise, first-time homebuyers have large home-related expenses. Lower initial mortgage payments and less interest rate changes are like a windfall to their already stretched finances. 

Here is a list of all of the associated  ARM mortgage benefits.

Lower initial interest rates

One of the most significant advantages of ARMs is the lower initial interest rate compared to fixed-rate mortgages. This initial period can vary, but usually ranges from one to seven years, offering a lower rate during this phase. 

Lower initial monthly payments

With lower interest rates come lower initial monthly payments. Buying a home comes with many expenses: choosing the best home insurance, home insurance rates, closing costs, moving into your new home, renovating parts of the house, and more. 

It makes sense that first-time buyers want to minimize their initial monthly payments to cushion their daily cost of living. 

Lower initial monthly payments are particularly beneficial for borrowers who anticipate an increase in their income over time or those who plan to sell their home before the fixed-rate period ends. 

You pay more principal

Lower interest rates give you financial room to pay more of the principal, if you can afford it. Remember that initial mortgage payments pay very little principal and interest. With a lower interest rate, there is more room left to pay for the principal. You can thus pay off your mortgage faster and own your home sooner. 


ARMs can be a suitable option for those who don’t plan on staying in their home long-term. If you plan to move, sell, or share the property before the adjustable period begins, you can take advantage of the lower rates without worrying about future rate increases. If your real estate has increased in value, your home equity is improved and you get to gain from selling a home. 

Cap limits

To protect borrowers, ARMs typically have cap limits that restrict the rise in interest rate during each adjustment period and over the life of the personal loan. This offers a level of security and predictability against overnight financing rates.

Benefiting from falling rates

If interest rates fall, borrowers with ARMs can benefit without needing a loan refinance, as their mortgage rates would adjust downward.

Benefits of Adjustable-Rate Mortgages for Businesses

For small businesses and companies, opting for adjustable-rate business loans can provide several advantages. 

The lower monthly payment associated with ARMs can ease the initial financial burden, allowing businesses and companies to allocate resources strategically, especially in their introductory period. 

By embracing ARMs, a small business can better manage the risk associated with fluctuating market conditions. In scenarios where things won’t work out as planned, the impact on the company’s finances is mitigated by the lower initial mortgage payment, providing a buffer against unexpected challenges.
