Important Disclaimer

CMAForge generates Comparative Market Analyses (CMAs) for real estate marketing purposes only. CMAs are not appraisals and should not be used for lending, legal, tax, or insurance purposes. Property values are estimates based on available market data and may vary from actual sale prices. For official property valuations required by lenders or for legal purposes, please consult a licensed, certified appraiser.

Accuracy metrics are based on internal testing comparing CMAForge estimates to actual sale prices within 6 months of generation. Past performance does not guarantee future results. Market conditions, property condition, and other factors may affect actual sale prices.
