County Overview
The 569 homes flipped in St. Clair County over the trailing 12 months ending July 2026 represent a consistent volume of investor activity. Each of these transactions involved a residential property purchased and resold within a year, signaling a dynamic market for value-add strategies. The average gross profit for these flips stood at an impressive $57,000. This profit margin contributes to the attractive 51.4% average gross ROI, which measures the gross profit against the initial purchase price. It is important for investors to note that this gross ROI does not account for renovation, holding, or selling costs, but it provides a clear indicator of the market's potential for profitable transactions.
Furthermore, the average time to flip in St. Clair County was 157 days. This turnaround speed suggests that investors are efficiently managing their projects, moving properties from acquisition to resale within approximately five months. Such a relatively quick capital turnover can be a significant draw for investors, allowing them to reinvest funds more rapidly. This average hold length places most flips within the "longer hold" category (6-12 months) as defined by BatchData, indicating that while capital turns quickly, investors are taking sufficient time for renovation and market positioning. The combination of solid gross profits, high gross ROI, and efficient turnaround times makes St. Clair County a compelling market for flippers.
