Land Values in Illinois: What to Know
Recent market data puts the median price of land in Illinois at about $48,300 per acre. The median sale was $64,000, across 4,757 land sales in 12 months, and land took an average of 193 days to sell.
Cook County, home to Chicago, has the highest price at about $685,300 per acre. The college towns and Chicago suburbs follow: Champaign County at about $148,100, Kane County at about $146,000 and Lake County at about $114,800. The wooded hills of far southern Illinois cost the least, with Hardin County at about $4,000 per acre and Pope County at about $4,900. Carroll County in the northwest is at about $3,100.
Why small lots cost more per acre
Illinois lots under 1 acre sold for about $128,300 per acre, with a median sale of $40,000. At 5 to 10 acres the figure is about $17,000, and at 20 to 50 acres about $8,800. Above that, the price per acre stays close to $8,500, because large tracts in Illinois are mostly productive farmland. Small lots cost more per acre because buyers pay for a ready building site with a road, not for the acres.
How to estimate what your land is worth
Start with sales of similar land near you. Match the size first, because a 2 acre lot and a 40 acre tract sell in different ways. Then adjust for road access, power and water at the road, and how much of the land sits in a flood zone. Land with no legal road access, or with a lot of wetland, often sells well below the county median. For farmland, the soil quality and drainage tile also change the price.
