We're building the most comprehensive property tax protest tool in Texas, one county at a time.
Caldwell County Appraisal District
Rural-to-suburban transition county southeast of Austin. Smaller market but growing fast; we carry full residential and mobile-home records.
Dallas Central Appraisal District
One of the fastest-growing metro areas in the country. Comprehensive data including building details, bedrooms, bathrooms, and condition ratings.
Harris County Appraisal District
The largest county in Texas. Our database includes over 1.1 million residential properties across the greater Houston metro area.
Hays Central Appraisal District
South of Austin along the I-35 corridor. Rapid growth in Kyle and Buda has pushed assessments up sharply; great data coverage for single-family and townhome comps.
Travis Central Appraisal District
Home to Austin, Travis County has seen some of the steepest property value increases in Texas. Our database includes over 353,000 residential properties with full assessment data.
Williamson Central Appraisal District
Austin's fastest-growing suburb. Some of the highest year-over-year assessment increases in the state — which often means the strongest protest cases.
