Initial Rate Duration
Definition and meaning of Initial Rate Duration in real estate.
The initial rate duration is the length of time during which the starting interest rate of an adjustable-rate mortgage (ARM) remains fixed. During this introductory period, the borrower's monthly principal and interest payments are guaranteed not to change.
In more detail
Depending on the structure of the hybrid adjustable-rate mortgage, the initial rate duration can last from several months to ten years. In a standard hybrid loan like a 5/1 ARM or a 7/1 ARM, the first number represents the initial rate duration in years, while the second number shows how often the rate adjusts afterward.
Home buyers often choose a specific duration based on how long they plan to stay in the home. If they plan to sell or refinance before the duration ends, they can capitalize on the lower introductory rate without facing adjustment risks.
