Executive Summary

Lovinger Partners is proud to present Porthole Marina, a rare opportunity to acquire an established waterfront marina on Grass Lake with direct access to the Chain O' Lakes, one of the Midwest's premier recreational boating destinations. The Property is improved with approximately 40 existing wet slips and offers investors the opportunity to acquire a highly constrained waterfront asset in a market characterized by limited new marina development and strong long-term fundamentals. Located in Antioch, Illinois, the property serves a diverse customer base from the greater Chicago metropolitan area, Northern Illinois, and Southern Wisconsin. The Chain O' Lakes continues to experience increasing demand for recreational boating, waterfront recreation, and marine services, while regulatory and environmental barriers have significantly limited the ability to create additional wet-slip inventory. As a result, existing marina properties benefit from a supply-constrained competitive landscape that supports long-term occupancy and asset value. In addition to its existing marina operations, Porthole Marina offers a compelling value-add opportunity to expand ancillary revenue through the development of a comprehensive marine services platform. The Property is well positioned to accommodate services such as boat repair, mechanical service, detailing, winterization, storage, brokerage, and marine retail, allowing an investor or owner-operator to capitalize on the growing demand for year-round boating support services throughout the Chain O' Lakes region. The Property's combination of existing waterfront infrastructure, strategic location, and operational upside provides multiple avenues for value creation. Investors have the opportunity to enhance cash flow through operational efficiencies, expanded service offerings, and targeted capital improvements while benefiting from the intrinsic scarcity of established marina assets. Porthole Marina represents a unique opportunity to acquire an irreplaceable waterfront investment in one of the Midwest's most recognizable boating markets, offering stable existing operations with meaningful potential for future growth and long-term appreciation.
