Overview
An adjustable-rate mortgage (ARM) is a type of home loan where the interest rate is not fixed for the entire loan term. Instead, it starts with a fixed rate for an initial period and then adjusts periodically based on a specified market index. ARMs often have lower initial rates compared to fixed-rate mortgages.
Key Characteristics
- Initial fixed-rate period (e.g., 3/1, 5/1, 7/1, 10/1 ARM)
- Rate adjusts after initial period (typically annually)
- Interest rate tied to market index (e.g., LIBOR, Treasury index)
- Margin added to index rate (lender's profit)
- Rate caps limit how much rate can increase
- Lower initial payments but potential for higher future payments
ARM Types
- 3/1 ARM: Fixed for 3 years, adjusts annually thereafter
- 5/1 ARM: Fixed for 5 years, adjusts annually thereafter
- 7/1 ARM: Fixed for 7 years, adjusts annually thereafter
- 10/1 ARM: Fixed for 10 years, adjusts annually thereafter
Rate Caps
ARMs have three types of rate caps: initial cap (limits first adjustment), periodic cap (limits subsequent adjustments), and lifetime cap (limits total increase over loan term). These caps protect borrowers from extreme rate increases.
