Formula

Housing budget = income/12 × DTI − monthly debts. Subtract monthly property tax and insurance to get the principal-and-interest budget, then invert the amortization formula to find the maximum loan and home price.

Frequently asked questions

Why include taxes and insurance?⌄

Lenders count your full housing payment (PITI) against the debt-to-income limit, not just principal and interest. Ignoring escrow overstates how much house you can afford.

What DTI should I use?⌄

A common guideline is 36% of gross income for total debt, sometimes up to 43–45% for strong applicants. Lower is safer.

Sources & methodology

Uses a debt-to-income cap covering full PITI — property tax and insurance are subtracted before deriving the loan. Excludes PMI and HOA.
