On a $350,000 loan, the spread between the cheapest and most expensive combination above
is the largest controllable number in the purchase. Two levers move it:
the term and
extra principal payments — both calculators accept this
amount directly. Wondering if that money belongs in the market instead? The
payoff vs invest comparison referees it fairly.
