A 5/1 ARM has an average rate of 5.98% 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.

Rates for new 30-year loans continue to bob around a bit above the low reached two weeks ago. Rates for several other loan types are also wavering.
