What is an adjustable-rate mortgage (ARM)?

An adjustable-rate mortgage (ARM) is characterized by an interest rate that fluctuates based on prevailing market conditions. This means that instead of maintaining a fixed interest rate throughout the entire loan term, the interest rate on an ARM can change at specific intervals, which typically occur after an initial fixed-rate period. These adjustments are often tied to a specific index, and the changes can lead to lower initial payments when compared to a traditional fixed-rate mortgage, but they also carry the risk of higher payments in the future if interest rates rise.

The nature of an ARM allows borrowers to potentially benefit from lower rates initially, making homeownership more accessible. However, it is crucial for borrowers to understand the risks associated with rate changes over time. This dynamic nature of an ARM is precisely what sets it apart from fixed-rate mortgages, which offer stability and predictability in terms of payments and interest costs throughout the life of the loan.
