What is the term for the limit on how much interest rates can increase over the overall life of an ARM?

The lifetime rate cap is the term used to refer to the maximum limit on how much the interest rate can increase over the entire life of an adjustable-rate mortgage (ARM). This cap provides borrowers with protection against extreme increases in interest rates, ensuring that while the rates can change periodically during specific intervals, there is a ceiling that cannot be surpassed regardless of market fluctuations.

This cap is crucial for borrowers' financial planning, as it gives them clarity and stability regarding their potential future payments. Thus, even if market interest rates rise significantly, borrowers with a lifetime rate cap will know the upper limit of their interest costs, allowing them to manage their budgets more effectively.

Understanding the lifetime rate cap is essential for anyone involved in mortgage lending, as it reflects the balance between risk for lenders and protection for borrowers.
