How to read the comparison

The tool calculates each offer's true cost using standard amortization. All numbers assume a fixed-rate mortgage with no prepayment penalty.

What is "5-year net cost"?

Total payments made over 5 years (principal + interest + PMI) plus upfront costs (points + lender fees), minus the principal equity you've built. This shows what you actually spend out of pocket in the near term.

What are "points" and should I pay them?

One point = 1% of the loan amount paid upfront to lower your rate. The break-even row shows how many months until the monthly savings cover the upfront cost. If you'll stay past break-even, points usually pay off.

Why does the "best" lender change based on how long I stay?

Low-rate, high-point loans win over long horizons. Low-fee, higher-rate loans win if you sell or refinance early. Adjust "Years you'll stay" to see the shift.

What's not included

Property taxes, homeowners insurance, HOA dues, and closing costs shared by all lenders (appraisal, title, recording). These don't affect the relative comparison between lenders.
