    Don’t forget property taxes and insurance; these can add significantly to your monthly outlay.
  4. Plan Extra Payments:
    Consider adding extra payments to reduce interest costs and shorten your loan term.
  5. Compare Lenders:
    Use the calculator to evaluate offers from multiple lenders to ensure you get the best rate.
