Question: what is a 5 and 1 arm?
Answer: A 5/1 hybrid adjustable-rate mortgage (5/1 ARM) begins with an initial five-year fixed-interest rate period, followed by a rate that adjusts on an annual basis. The "5" in the term refers to the number of years with a fixed rate, and the "1" refers to how often the rate adjusts after that (once per year).
