A 5/1 ARM has an average rate of 5.88% today. You’ll typically get a lower introductory interest rate with a 5/1 ARM in the first five years of the mortgage. But you could pay more after that period, depending on how the rate adjusts annually. If you plan to sell or refinance your house within five years, an ARM could be a good option.

Although mortgage rates mainly fell after reaching a high in spring 2024, they surged again in October 2024.
