Affordability is about more than the maximum amount a lender may approve. The better question is what monthly housing cost fits your actual life while leaving room for savings, maintenance and everything else you care about.
REAL-WORLD PAYMENT MODEL
Mortgage & homeownership calculator
Model conventional, FHA, VA and USDA financing, then see the payment, estimated cash to close, mortgage/program fees, ownership reserve and debt-to-income ratios in one place.
Program-fee assumptions use published federal guidance for FHA mortgage insurance, VA funding fees, and USDA guaranteed-loan fees. Private PMI, interest rates, taxes and insurance are not standardized and should be replaced with property- and borrower-specific figures.
What belongs in the monthly number?
Principal and interest are only the starting point. Property taxes, homeowners insurance, association dues, mortgage insurance, flood/wind coverage where applicable and a realistic maintenance reserve can materially change ownership cost.
Keep cash-to-close separate.
Down payment, lender costs, title/settlement expenses, prepaid taxes/insurance and other closing items affect the cash needed even when the monthly payment feels comfortable.
Use multiple scenarios.
Run the calculator at different prices, down payments and rates. Then take the planning range to a licensed lender for actual loan options and disclosures.
