How to read this

The big number is your full monthly housing payment — often called PITI: principal, interest, taxes and insurance. Lenders love to quote only the first two, which is why the figure on a listing always feels lower than reality.

Watch the interest line. On a 30-year loan, the first decade is mostly interest; equity builds slowly at first and then accelerates. Shortening the term to 15 years roughly doubles the principal portion of each payment but can cut total interest by more than half.
