Champaign County is situated in east-central Illinois and is part of the greater Champaign–Urbana metropolitan area.The county was incorporated on February 20 1833. The county seat is Urbana; central city is Champaign. This county has a more urban / suburban mix thanks to the presence of the University of Illinois Urbana–Champaign and a strong economic/technology base. Housing is varied: downtown and campus-adjacent housing includes apartments, town-homes, newer subdivisions, and single-family homes; moving out into the suburbs you’ll find newer subdivisions, larger homes, and still agricultural fringes. Home prices here are significantly higher than the rural counties: typical existing home purchase in mid-2025 might be in the range of $300,000-$450,000 for standard single-family homes, with newer builds or larger lots potentially reaching $500,000-$700,000+. New construction cost plus land will often start in the $400,000-$600,000 bracket for modest new homes and higher for premium lots and finishes. Because of the metro and university pull, the area is more suburban/urban mixed, with strong demand. Proximity: the county sits roughly ~135 miles southwest of Chicago. Towns and villages include Champaign, Urbana, Mahomet, Savoy, St. Joseph, and Rantoul. The lifestyle offers urban amenities (arts, shopping, culture) with Midwestern friendliness.
