KLM Builders is not currently building new inventory in this Illinois market — every listing across its 11 communities represents resale opportunity rather than a builder price sheet, spread across McHenry and Lake County towns. In Spring Grove, KLM built Forest Ridge, North Ridge, and Thousand Oaks, with Forest Ridge resales currently around $865,000 and North Ridge near $600,000. Antioch is home to Woodland Ridge, priced $345,000 to $500,000, and Woods of Antioch, near $436,900. In Richmond, KLM's Sunset Ridge and Sunset Ridge Estates offer resale homes from $485,000 to $530,000. Round Lake Heights features Fox Glenn, priced $344,000 to $424,900, while Johnsburg's Running Brook Farm starts around $315,000, and Grayslake's Lake Center Place rounds out the collection. Streamwood also has its own Forest Ridge, with resales between $355,000 and $385,000. Buyers considering these subdivisions should expect mature landscaping, established streetscapes, and no new-construction HOA assessments — home age and condition vary widely from one resale to the next, so a firsthand walkthrough matters more than the original builder specs.
