Description

A compelling investment and redevelopment opportunity in the heart of Marathon, this multi-family property offers immediate use along with significant long-term potential in one of the Florida Keys' most active markets. Fronting Overseas Highway with excellent visibility and convenient access, the property includes two concrete block buildings. One structure is configured as a three-bedroom, two-bath residence, while the second is arranged as a duplex with two efficiency studio units, each with a private bath. The property includes three residential property rights, creating flexibility for continued income-producing use or future redevelopment. For investors and developers, the location and existing configuration open the door to a variety of possibilities, whether the goal is to maintain the current multi-family setup, reposition the site, or pursue a larger development strategy. An additional opportunity exists to acquire the adjacent parcel along with submerged land rights, allowing a buyer to assemble a larger contiguous footprint and expand the potential of the overall site. Both properties are offered together under MLS number 620305. With its central Marathon location, direct Overseas Highway access, established residential use, and added development upside, this property presents a rare chance to secure a versatile piece of the Florida Keys market.
