How often does an adjustment interval occur in an adjustable-rate mortgage (ARM)?

In an adjustable-rate mortgage (ARM), the adjustment interval is defined by the specific terms of the loan agreement. This means that the frequency with which the interest rate on the loan is adjusted can vary widely based on what is explicitly stated in the loan documents. It is not limited to a fixed time period such as monthly, annually, or every few years; instead, the adjustment can occur at any interval as agreed upon by the lender and borrower.

For example, some ARMs may adjust monthly, while others may adjust annually or at different intervals like every three or five years. The key point is that this adjustment is predetermined and included in the loan's specific terms, allowing for flexibility in structuring the loan according to the needs of both the lender and the borrower. Understanding this concept is crucial for managing expectations about how often payments may change and planning accordingly.
