When to consider a 15-year fixed-rate mortgage

The main draws of 15-year fixed-rate loans are their lower interest rates and the fact that they’ll be paid off more quickly. Like any fixed-rate loan, they also offer stability; the monthly payment won’t change no matter what happens to inflation or market interest rates.

But the monthly payment will be much higher than that of a 30-year loan for the same property due to the shorter term, and that will make it harder to qualify for the loan.

When to consider a 30-year fixed-rate mortgage

You can likely claim a sizable tax deduction based on interest payments for your 30-year loan, especially in the early years, when most of your payments go toward interest. And because it’s a fixed-rate loan, you’ll pay the same amount every month.

However, if you don’t plan to stay put for several years, or if you want a lower rate, a 15-year fixed-rate mortgage or an adjustable-rate mortgage might be a better option.
