What the 15-year payment buys on a 30-year clock.

We’re not a lender. Principal & interest only — taxes, insurance and any PMI ride on top of both. Lenders qualify you on the payment, so the 15-year may approve a smaller loan; an extra-principal habit on a 30-year (see Early payoff) keeps the flexibility. A lender will price both for you — we’ll introduce you below.
