- Adjustable Rate Mortgage (Arm)
- A mortgage loan with an interest rate that fluctuates in accordance with a designated market indicator -- such as the weekly average of one-year U.S. Treasury Bills -- over the life of the loan. To avoid constant and drastic fluctuations, ARMs typically limit how often and by how much the interest rate can vary.
