What zipradar shows

Pages show the county millage rate, assessment methodology, homestead and senior exemptions, and a link to the assessor's portal for address-specific searches.

Refresh cadence

Annual reassessment per county. zipradar honors the regulator's publishing cadence; stale data is flagged rather than silently served.

Limitations

Top-50 metros covered at launch (~35% of US population). Smaller counties link directly to the assessor portal with a 'data coming soon' note.
