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.
