Boone County is in northern Illinois, formed in 1836 and named in honour of the frontiersman Daniel Boone. The county seat and largest city is Belvidere. It is part of the greater Rockford, IL metropolitan region. Significant communities include Belvidere, Poplar Grove, Capron, Cherry Valley, Timberlane and Garden Prairie.The housing market here skews more suburban / semi-urban compared to many rural Illinois counties: you’ll find newer subdivisions, single‐family homes of varied size, and also remaining agricultural acreage particularly on the outskirts. The average home value as of September 2025 was about $325,000 per Redfin for home sales in Boone County. Other data show a Zillow average home value around $273,739. Given the stronger market and proximity to Rockford (and about ~75 miles northwest of Chicago) the cost to build a new home would likely be in the mid-hundreds of thousands (e.g., $300K-$500K plus land) depending on size and finishes. The county is a mix: urban clusters around Belvidere with amenities, and more rural land further out. The proximity to a larger city (Rockford) and access to Chicago’s sphere gives it a transitional suburban-rural feel.
