You can ask questions before deciding what to do.
Share the location, acres and when you’d like to sell. Mention any loan, unpaid taxes or shared owners.
We look at the information you send. If we need more to review the land, we’ll ask. You can ask how any proposed offer works.
Read the written price, costs, dates and conditions. If you choose to move ahead, confirm the next steps with the people handling the closing.
Choose the area where the land sits, even if you live somewhere else.
In Illinois, the office may be called the county assessor, supervisor of assessments or township assessor. These offices keep records used for property taxes. If you do not know where to search, ask the county’s main assessment office. The state guide below explains how the offices work.

Start with the county where the land sits. Explain that you need help finding the record for land you may sell. Ask which office handles it and whether you can search online. The office title can differ, so don't assume every county uses the same search site.
Have the land ID and owner name from the tax bill ready. If you know the township, include it too. Keep a copy of the bill beside the deed so you can compare the names, acres and location. If a field doesn't match, write down the difference and ask the office about it.
For a farm with buildings, note what you want to sell: all of it, the land only, or part of the property. A record that includes a house won't tell you the value of bare land by itself. When you compare offers, use the same land and buildings for each one. Our offer calculator helps you compare the money you'd keep.

You don’t need a perfect file to start. A clear note is more useful than a guess that sounds certain.
For example: “I own about five acres in this county. I have the tax bill, but I haven’t found a survey. I’d like to compare offers before deciding.”
