See how much house you can afford based on your income, debts, and down payment — using the same 28%/36% guideline lenders use.
Estimate using the 28/36 qualifying guideline. Actual approval depends on credit, PMI, HOA dues, and lender rules. General information, not a mortgage offer or financial advice.
Lenders use two ratios. The front-end (28%) caps your total housing payment at 28% of gross monthly income. The back-end (36%) caps housing plus all other debt at 36%. Your true budget is whichever comes out lower — which is why paying down a car loan can raise the house you qualify for.
Monthly housing budget = min(28% × income, 36% × income − other debts)
We then back out the home price that fits that budget at your rate, term, and estimated taxes + insurance.
A long-standing lending guideline: keep housing costs under 28% of gross income and total debt under 36%. It's a starting point, not a hard limit — some loan programs allow higher.
Yes — the estimate is PITI (principal, interest, taxes, insurance). Add HOA dues and PMI separately if they apply to your situation.
Increase your down payment, pay off other monthly debts, improve your rate, or extend the term. Each one lifts the price your budget supports.
