- Step 3: Review the calculation steps and final result.
Frequently Asked Questions (FAQ)
How does an ARM work? An ARM starts with a lower interest rate than a fixed-rate mortgage, but the rate can increase after a set period.
What are the risks of an ARM? The main risk of an ARM is that your interest rate may increase, causing your payments to rise after the adjustment period.
Should I choose an ARM or a fixed-rate mortgage? An ARM is best if you plan to sell or refinance before the interest rate adjusts, whereas a fixed-rate mortgage offers predictable payments for the life of the loan.
