Adjustable-rate mortgage programs charge a fixed-interest rate for the first three, five, seven, or ten years. After that time, the loan turns into a variable interest rate loan (with a rate cap) for the remaining years on the life of the loan, based on the then-current interest rates.
When it comes to Adjustable-Rate Mortgages (ARMs), there is a basic rule to remember: The longer you ask the lender to charge a specific rate, the more expensive the loan.
If you plan to own the house for three years or less, the perfect loan is one that is fixed for three years before starting to adjust. This way you’ll benefit from the lower rate offered by an ARM without being subjected to the uncertainty of payments that could be higher. Similarly, if you think you’ll be in the house for five or fewer years, the perfect loan is our loan that is fixed for five years before starting to adjust. The same logic applies to our loan that is fixed for seven years before adjusting.
