Verify Parcel Identity
Confirm the parcel number, situs address, legal description, acreage, land class, and map boundary with county GIS.
Land buyer checklist
How to research land before buying it.
Good land research starts before the drive-by. Use parcel records, tax history, owner information, terrain, flood risk, soils, access, utilities, and county source links to decide whether a property deserves deeper due diligence.
Before making an offer
Check the parcel from more than one angle.
Review Ownership
Look at owner name, mailing address, related parcels, owner history, trusts, entities, and recorder records.
Check Taxes
Review annual tax, unpaid balances, due dates, exemptions, assessments, tax-sale flags, and payment history.
Study Buildability
Screen slope, low ground, floodplain, soil limitations, road frontage, driveway access, utilities, and zoning.
County records to check first
Start with the assessor, treasurer, GIS viewer, recorder, planning or zoning office, and any county tax search portal. If the parcel is rural or wooded, add FEMA flood maps, NRCS soil survey, elevation data, and local utility maps where available.
Common red flags
Watch for unclear access, steep terrain, floodplain, unpaid taxes, special assessments, very small buildable areas, mismatched acreage, unusual ownership history, missing road frontage, and parcels that look cheap because development would be difficult.
How Illinois Land Index helps
Illinois Land Index is built to turn parcel files into a shorter research queue. It does not replace county verification, but it helps decide which properties deserve that time by combining acreage, owner, tax, terrain, credit access, and market context into one workflow.
