About this home

Presenting 77 S Conch Key, a 4,500-square-foot parcel in the heart of the Florida Keys that includes two transferable ROGO allocations, each with an estimated value of approximately $149,000. The property is approved for development under existing ROGO plans allowing for up to four residential units, creating a rare opportunity for investors, developers, or end users seeking to build in a market where development rights are increasingly limited.The value of this offering extends beyond the land itself. The included ROGO allocations provide a significant entitlement advantage, reducing the time, uncertainty, and cost often associated with securing build rights in the Florida Keys. Whether utilized for a private compound, vacation residences, workforce housing, or an income-producing investment, the property offers flexibility and long-term upside.While the site does not include water access, it benefits from a central Conch Key location with convenient access to Marathon's marinas, restaurants, shopping, and recreational amenities. Opportunities to acquire buildable Keys property with transferable allocations and approved development plans are increasingly scarce, making 77 S Conch Key a compelling development and investment opportunity. Conch Key is a hidden gem within the Middle Keys, an extension of Marathon—the vibrant heart of the Florida Keys. This small, exclusive island offers the tranquility of a private retreat with the convenience of nearby Marathon’s restaurants, marinas, shopping, and the Marathon International Airport. Residents enjoy easy access to both Islamorada and Key West, making Conch Key a rare blend of seclusion and accessibility in one of the most desirable stretches of the Keys.
