Mortgage Cost, Clearly Broken Down
Think in total housing cost, not only loan payment. PITI gives the complete monthly picture.
Core Formula (Principal + Interest)
M = P × [r(1+r)^n] / [(1+r)^n − 1]
Lower Total Mortgage Cost
Improve credit
Better score usually means lower rate.
Increase down payment
Can reduce risk and avoid PMI.
Compare lenders
Small rate differences matter over decades.
Add extra principal
Cuts payoff time and lifetime interest.
