Investment Insights

Based on property information with market context.

This vacant residential homesite in Marathon is set up for a custom Florida Keys build, offering 65 feet of water frontage along with the flexibility to design for privacy and water-oriented living. The property includes a newer set of plans for a 3-bedroom, 2-bath residence that may be submitted by the next owner, providing a head start for buyers who want to move forward using the existing design. If preferred, buyers may also submit new plans to pursue an improved BPAS standing, subject to City of Marathon review.

The parcel is located on Treasure Road in a waterfront neighborhood, tucked away on a quiet dead-end street and described as being just moments from Sombrero Beach. While neighboring homes are positioned for water views, buyers should evaluate site-specific sightlines based on their chosen elevation and design. The property is currently in the City of Marathon’s BPAS allocation system and is ranked #17 in the most recent allocation round with 68 points, though all requirements and permitting must be confirmed with the City.

For the right buyer, this site can support a developer-led or owner-custom approach to building an island residence, with planning materials already available to streamline early steps. Interested parties should plan to coordinate BPAS submittal and permitting directly with the City of Marathon as part of the purchase and construction process.
