What used to take a consultant two weeks, AppealScore does in under five minutes.

1

Enter your property

Address, property type, and your current assessed value. Takes 60 seconds.

2

AI researches comparables

Our system pulls recent sales, lease comps, and market trends for your area.

3

Get your Appeal Score

Instant overassessment detection, estimated tax savings, and win probability.

4

Download your appeal packet

A complete, jurisdiction-specific appeal document ready to file — or hand to your attorney.

Built for commercial property owners

Whether you own one building or five hundred, AppealScore scales to your portfolio.

🏢

Office & Retail Owners

Post-pandemic valuations haven't caught up with the market. You're likely overpaying.

Rapid appreciation means assessors often overshoot. We find the gap.
