Always consider your cost of living. Arkansas an affordable state. Illinois is outrageous compared to Indiana. Especially anything North of I-80 and East of I-39.
The suburbs of Chicago are double the cost of anywhere in Indiana and it gets worse as you get closer to city.
I've seen houses that sell for less than 100k in South Bend sell for 3-6 times as much in Chicago and close suburbs like Brookfield, Berwyn, etc.
The far suburbs like Downers Grove have had a decent correction, but still about double over nice Indiana neighborhood and don't forget Illinois sky high property taxes. Average in DuPage county about 7k a year for average house and 14k year for custom.
