Interest-Only 3/1 ARM

Here we look at a 3/1 ARM with an interest only period that matches the 3 year fixed period.

Assuming that the index rate remains unchanged throughout the life of the mortgage, when you press the Calculate button you'll see that after 3 years that the principal balance remains at the original loan amount and more than $12,000 per year has been paid in interest. At the beginning of year 4 the loan is fully amortized and the minimum monthly payment increases by $211 or 21%.
