Bureau County (county seat: Princeton) is a largely rural, agricultural county with historic river towns (Princeton, Spring Valley, Ladd, Walnut, DePue) and a mix of Victorian/main-street homes in town centers and farmsteads in the countryside. Housing is predominantly single-family, older historic homes in towns and modest ranches or farmhouses elsewhere. Market values typically fall in the $130k–$180k range for many existing homes (varies by town/condition). New build costs in Illinois commonly run ~$120–$200 per sq ft (mid-range), so a typical 1,800 sq ft home could cost roughly $216k–$360k to build before land/site costs. Bureau County is roughly ~100 miles to Chicago (depending on town) and nearer to regional cities like Peoria/Rockford for larger services.
