This is a qualification calculator, not a pre-approval. Actual lender approval depends on documented income, asset reserves, employment history, and the specific loan product. Use this to shop honestly - bring it to a lender to lock in a real pre-approval letter.
Regional varianceReal estate figures vary by market and state. Property values, closing costs, insurance, and property tax rates differ significantly by county and state. This tool gives a directional estimate; a licensed agent or lender in your market can produce the exact numbers.
