How accurate is this calculator?
This calculator estimates your maximum mortgage by applying standard debt-to-income ratios (45% of gross monthly income, or 50% with 20%+ down) to your housing payment plus existing debts. It then iteratively backs out the largest home price whose full PITI payment fits within that limit, using state-specific tax and insurance escrow factors. Real lenders use additional underwriting criteria including credit score, employment history, asset reserves, and program-specific guidelines (FHA, VA, conventional). Treat this as a planning estimate.
