It is no secret that the Sombrero Beach neighborhood is one of the most highly sought after established neighborhoods in all of Marathon. Rarely does a vacant lot become available with a building right already attached to it. What makes this 7,125 sqft lot even more rare is that this one comes with approved plans to build a 4 bed, 3 bath, 1966 sqft living home with a 299 sqft rear porch & 75 sqft front porch by the well-respected local builders, Design Center. To make things even easier for the buyers, a local lender is offering up to 80% LTV Construction Financing, allowing you to purchase the lot and fund the construction all at once. It is important to note that this building right is designated SOLEY for local Marathon residents who will make this their Homesteaded primary residence for a minimum of 2 years. This provides a great opportunity for a local family to live in this incredible neighborhood that is walking distance to Sombrero Beach and minutes to Marathon High School. Don't miss the rare opportunity.
