I'm actually pretty happy with my mortgage. I got a good deal in 2013 and refinanced to a 15yr at 3.25% a couple years ago. It's the definition of "good debt" because inflation and my home's value has way out paced the interest.
I've given up. The interest rates are ridiculous, and home prices where I want to live (anywhere in the western USA pretty much) are insanely inflated.
OMG. I got 8.95% for a 25yr mortgage and it was an awesome deal. Market was about 13.5%.
Your numbers are really just free money from where am standing.
