Presenting an unparalleled investment opportunity at Mile Marker 98 in the Upper Florida Keys, 91865 Overseas Highway offers 143 feet of prime frontage along one of the most visible stretches of the Overseas Highway. This fully repositioned mixed-use portfolio consists of five completely renovated commercial buildings and ten residential units, all backed by long-term leases that provide immediate and dependable cash flow. The property underwent a comprehensive full-gut redevelopment, including new 2024 metal roofs, impact windows and doors, upgraded plumbing and electrical systems, new stucco and paint, and premium paver hardscape—resulting in a highly resilient, low-maintenance asset ideal for long-term institutional ownership. With a Pro Forma NOI of $395,250 and the owner guaranteeing 100% occupancy at closing, the property functions as a turnkey, stabilized income stream from day one. The asset sits on a 0.49-acre parcel in Tavernier, one of the most constrained and high-demand markets in the Upper Keys, where limited developable land, high barriers to new construction, and consistent year-round population and tourism activity drive strong rent durability and long-term appreciation. This corridor supports a wide range of service-based, retail, and residential uses, and the property's diversified tenancy minimizes operational risk while maximizing upside through future rent growth. In a market defined by scarcity, rising replacement costs, and persistent tenant demand, 91865 Overseas Highway represents a rare chance to acquire a fully modernized, de-risked, high-cash-flow coastal asset with exceptional long-term fundamentals and virtually no near-term capital exposure.
