Frequently Asked Questions
How is the maximum home price calculated?
It finds the largest monthly housing payment (PITI) allowed by your front-end and back-end debt-to-income limits, then solves for the home price whose principal, interest, taxes, insurance, and PMI fit exactly within that payment.
What are front-end and back-end DTI ratios?
Front-end DTI is your housing payment divided by gross income — commonly capped around 28%. Back-end DTI is your housing payment plus all other debt payments divided by gross income — commonly capped around 36%, though some loan programs allow higher.
Does this include PMI?
Yes — if the resulting down payment works out to less than 20% of the home price, PMI is factored into the affordability math automatically.
Why might a lender approve me for more or less than this?
Lenders also weigh credit score, cash reserves, loan program, and other factors this calculator doesn't see. Actual pre-approval amounts can differ from this estimate in either direction.
Is this financial advice?
No — this is an estimate for planning purposes only, not financial advice. Get pre-qualified with a lender for an accurate number.
