AI Data Quality Control
Comparative market analysis for smarter valuations.
The intelligent appraisal module built for local government assessment offices.
Mass appraisal sales analysis isn’t easy. Outdated tools, manual spreadsheet tweaks, hidden market outliers and inaccurate comp selections leave offices racing valuation deadlines while risking appeals. AI Data Quality Control pairs every subject parcel with the best comparables, flags mis-assessments across your county in seconds and hands the right parcels to the right appraisers. It is a second opinion for your staff: the assessor’s values change only when your appraisers change them.
How it works
Defend every value with confidence.
Find the best comps
Automated similarity scoring and fit radar charts pair each subject parcel with neighborhood comparables.
Catch mis-assessments
Outlier detection flags value discrepancies across your entire county.
Check the whole county
Sales ratio studies and accuracy tests on held-out sales show where values stand against the market.
Hand off the work
