A combination fixed rate and adjustable rate loan – also called 3/1,5/1,7/1 – can offer the best of both worlds: lower interest rates (like ARMs) and a fixed payment for a longer period of time than most adjustable rate loans. For example, a “5/1 loan” has a fixed monthly payment and interest for the first five years and then turns into a traditional adjustable rate loan, based on then-current rates for the remaining 25 years. It’s a good choice for people who expect to move or refinance, before or shortly after, the adjustment occurs.
