10/1 Adjustable Rate Mortgage (10/1 ARM)

Adjustable Rate Mortgage

10/1 ARM - the rate is fixed for a period of 10 years after which in the 11th year the loan becomes an adjustable rate mortgage (ARM). The adjustable rate is tied to the 1-year treasury index and is added to a pre-determined margin (usually between 2.25-3.0%) to arrive at your new monthly rate. Ask what the margin, life cap and periodic caps of your ARM will be in the 11th year. The loan is fully amortized (or paid off) in 30 years if the normal payment schedule is followed. (Also see anatomy of an ARM for additional information). Sometimes called a 10 and 1.
