About Illinois, United States

The state's housing market benefits from Chicago's strong employment base, world-class cultural amenities, and transportation infrastructure including one of the nation's busiest airports and commuter rail systems. Chicago offers a unique urban housing market with a mix of high-rise condos and apartments in the downtown Loop and surrounding neighborhoods, vintage courtyard buildings, and classic two-flats and three-flats in residential areas.

Different regions of Illinois offer varying price points from urban condos in Chicago's West Loop starting at $400,000 to suburban single-family homes in the $300,000-$500,000 range to rural properties in downstate Illinois under $150,000. Illinois faces some housing market headwinds from population decline and property tax burdens, but stable employment in healthcare, finance, and professional services supports continuing demand.
