A Mortgage That Feeds Your Piggy Bank

This summer, we finally decided to take the plunge we’d been contemplating for a while: converting our 30-year mortgage to one with a 15-year payoff. It’s a big step. Our payments will go up somewhat (the PITI -- principal, interest, tax, and insurance -- will rise by 19 percent), and every financial analyst I know is mentally screaming in anguish at the thought of taking money I could be investing, and pouring it into earlier payoff of a low-interest (low, tax-deductible interest) loan.
