Forest Gate, Oak Brook — True Cost of Ownership
DuPage County | 78 homes | Attached condos | Units $280K–$460K | HOA ~$750/mo
Forest Gate is a smaller, more exclusive community than its Oak Brook neighbor Briarwood Lakes, with 78 homes and an HOA at approximately $750/month — the single highest fee in the Chicago market. The same analysis applies as at Briarwood Lakes: a comprehensive condo HOA at this level bundles items that single-family homeowners pay separately. Heat, cooling, water, cable, building insurance, exterior maintenance, and grounds care are typically all included. Oak Brook's DuPage County property tax rate of ~2.0% is a relative advantage over higher-rate county alternatives.
The 78-home scale places Forest Gate in the intimate community category — smaller than most 55+ communities in this guide, which has implications for both social life and HOA governance. Smaller HOA communities have less reserve fund diversification and can be more exposed to special assessments if a major capital expense arises. Due diligence on the reserve fund is particularly important at communities this size.
