Field notes
The comparison is based on assessed value per square foot among near-identical homes in the same block group. AppealComps says users submit any appeal themselves to the Assessor or Board of Review; filing is free, and the site does not file appeals or provide legal advice. Its tax estimates use the 2025 state equalisation factor of 3.03 and a 7% composite rate, while directing users to their own bill for their actual rate.
