How often can interest rates change in a 5/1 adjustable-rate mortgage?

In a 5/1 adjustable-rate mortgage (ARM), the structure of the interest rate changes is clearly defined. The "5" in the designation indicates that the initial interest rate is fixed for the first five years of the mortgage term. After this initial fixed period, the "1" signifies that the interest rate can adjust annually thereafter.

Therefore, after the first five years of the loan, the interest rate on a 5/1 ARM can change every year. This annual adjustment allows the interest rate to reflect current market conditions, which can lead to varying payments for the borrower depending on fluctuations in interest rates.

Understanding the parameters of how frequently the rate can change is crucial for borrowers, as it impacts their potential monthly payments and overall financial planning over the mortgage term.
