What does the property check produce?
An appeal-readiness artifact: stop, gather more official proof, or prepare a self-file packet when evidence is strong enough.
FAQ
Plain answers before you start.
Does every county have a page?
Yes. Every Illinois county has an indexed county page with Available, Limited, or Not available yet.
Is there an unsupported-county signup list?
No. If a county is not available yet, the page simply says what official document to keep ready.
What should I upload?
Only official property documents requested inside the signed-in flow, such as assessment, parcel, tax, or appeal PDFs.
What happens when support is weak?
AssessLess should tell you to stop before spending more time or money on a packet.
