What is a Comparative Market Analysis (CMA)?

A Comparative Market Analysis (CMA) is the foundation of real estate valuation. Used by appraisers, agents, and investors worldwide, a CMA determines property value by analyzing recent sales of similar properties in the same area.

Why CMAs Matter:

  • Lenders require them: Banks use CMAs to approve mortgages and determine loan amounts
  • Investors depend on them: Accurate valuations prevent costly overpayments
  • Agents use them daily: Every listing price and offer strategy starts with a CMA
  • Courts accept them: CMAs are legal evidence of property value in disputes

Our calculator follows the exact 6-step process that licensed appraisers use, including comparable selection criteria, adjustment calculations, and confidence ratings. The result? Professional-quality analysis that you can trust for major financial decisions.
