What Is an Adjustable Rate Mortgage? Pros, Cons & When It Makes Sense

Should You Choose an Adjustable Rate Mortgage in Michigan? Here’s What to Know.


If you’re shopping for a home loan in Michigan, you’ve likely come across the term Adjustable Rate Mortgage — also called an ARM.

These types of mortgages can offer lower initial interest rates, but they come with some important differences compared to traditional fixed-rate loans.

In this post, we’ll break down:

  • What an ARM actually is

  • How adjustable rate mortgage rates work

  • The pros and cons of ARMs

  • And whether an ARM might be right for your homebuying goals


What Is an Adjustable Rate Mortgage?

An Adjustable Rate Mortgage (ARM) is a home loan with an interest rate that can change over time. Most ARMs start with a fixed-rate period (usually 5, 7, or 10 years), followed by a period where the interest rate adjusts at regular intervals — often annually.


Common ARM Terms:

  • 5/1 ARM = Fixed rate for 5 years, then adjusts once per year

  • 7/6 ARM = Fixed for 7 years, then adjusts every 6 months

  • Adjustment Cap = A limit on how much your rate can increase at each change

  • Lifetime Cap = A limit on how high your rate can ever go


Why Choose an ARM?

1. Lower Initial Interest Rates

The big draw of ARMs is that their starting rates are often significantly lower than fixed-rate mortgages. This can mean lower monthly payments — especially helpful if you’re trying to qualify for more home or build savings in the early years.

2. Great for Short-Term Homeowners

If you plan to move, refinance, or pay off the loan before the fixed-rate period ends, an ARM can help you save money upfront.

3. Rate Caps = Some Protection

Most ARMs come with built-in caps to limit how much your rate (and payment) can rise, so you won’t be totally at the mercy of the market.


What Are the Risks of an ARM?

1. Uncertainty After the Fixed Period

Once the introductory period ends, your rate can increase — sometimes significantly — depending on market conditions.

2. Harder to Budget Long-Term

If your income is tight or you’re not planning to move anytime soon, the payment variability might cause stress down the road.

3. Not Ideal in Rising Rate Markets

If interest rates are trending upward, your adjustable rate could reset higher than a fixed-rate alternative.


Is an Adjustable Rate Mortgage Right for Me?

You might consider an ARM if:

  • You expect to move or refinance before the fixed-rate period ends

  • You want to maximize buying power with a lower initial rate

  • You’re comfortable with some interest rate risk later on

  • You’re purchasing a starter home, second home, or investment property
