Works backward from your income, debts, and down payment — with property tax and insurance actually factored into the price, not bolted on after.
36% back-end DTI is a common conventional guideline — some lenders and loan types (FHA, for instance) allow more. Property tax rate defaults to a rough U.S. average; check your county's actual rate for a tighter number.
Principal, interest, property taxes, homeowners insurance, and HOA dues — each has its own input — measured against the debt-to-income ratio you specify. It does not include PMI, which most lenders add when your down payment is under 20%.
Most conventional lenders cap total DTI around 36–43%, though some programs allow higher. 28% front-end (housing-only) is a common conservative benchmark.
Lenders factor in your full credit profile, other debts, and program-specific rules — this tool gives a general estimate, not a guarantee.
