In an adjustable-rate mortgage (ARM), when does the interest rate typically change?

• A. After a fixed term only
• B. At the borrower’s request
• C. Periodically based on financial indexes
• D. Once the loan is fully paid

Answer: (C)

In an adjustable-rate mortgage (ARM), the interest rate typically changes periodically based on financial indexes. This means that the interest rate is tied to a specific index, such as the LIBOR or the Treasury index, and will adjust at predetermined intervals based on the performance of that index. As a result, the borrower’s monthly payment can fluctuate over time, reflecting changes in market interest rates.

An adjustable-rate mortgage is designed to provide initial lower rates compared to fixed-rate loans, appealing to borrowers who may expect to move or refinance before the adjustments significantly impact their payments. The adjustment period is usually specified in the loan terms and could occur annually, semi-annually, or after another set period.

In contrast, adjusting the rate solely after a fixed term, at the borrower’s request, or only once the loan is fully paid does not align with the standard mechanics of an ARM, where periodic adjustments are based on a broader financial index rather than borrower discretion or completion of payments.
