Fixed-rate mortgage vs. adjustable-rate mortgage

Homebuyers who choose a fixed-rate mortgage enjoy the comfort and predictability of knowing monthly payments won’t change. Two common types of fixed-rate mortgages include the 30-year and the 15-year mortgage, but other terms can range from 8 years to 30 years.

An adjustable-rate mortgage, or ARM, typically starts with a lower interest rate than a fixed-rate mortgage. However, your interest rate and payments are periodically adjusted up or down as the index changes. In the event these rates change, you may refinance your ARM to a fixed-rate mortgage to avoid fluctuating monthly payments.
