How we work
Public records only
Every figure comes from Cook County Assessor and Recorder data and traces back to its source record.
Ranked before the window opens
We screen each township ahead of its filing window, so your team spends prep time on the strongest cases.
Built for firms
We are not a law firm and do not represent property owners. Packets are prepared for attorney review.
