What Is an Adjustable-Rate Mortgage (ARM)?
An adjustable-rate mortgage (ARM) is a home financing option that offers a lower initial interest rate for a fixed period, after which the rate adjusts periodically based on market conditions. Unlike fixed-rate mortgages, ARMs provide borrowers with lower initial payments and the potential for rate decreases, making them an attractive option for borrowers who plan to sell or refinance before the rate adjustment period begins.
​
Key Features of Adjustable-Rate Mortgages:
-
Lower Initial Rate: Lower interest rate for initial fixed period
-
Rate Adjustments: Rate adjusts periodically after initial period
-
Flexible Terms: Various initial fixed periods available
-
Rate Caps: Limits on how much the rate can increase
-
Index-Based: Rate tied to market index
-
Refinancing Option: Can refinance before rate adjustment
​
Adjustable-rate mortgages are essential for borrowers who want lower initial payments and are comfortable with the potential for rate changes. They provide the flexibility and affordability needed for short-term homeownership strategies.

How Adjustable-Rate Mortgages Work
Understanding the mechanics of adjustable-rate mortgages is crucial for determining if this financing option is right for your situation.
​
The Adjustable-Rate Mortgage Process
Adjustable-rate mortgages work by offering a lower initial interest rate for a fixed period, after which the rate adjusts periodically based on market conditions. This provides borrowers with lower initial payments and the potential for rate decreases.

After the initial period, your rate adjusts periodically based on market conditions and the specified index.
​
Monthly Payments
Make monthly payments that may change based on rate adjustments, though rate caps limit increases.

Refinancing Option
You can refinance before the rate adjustment period begins to lock in a fixed rate.
