Overview

Description

Waterfront, buildable RV lot in Key By the Sea in the heart of Marathon! Enjoy 28' of water frontage with quick, direct ocean access. This lot has a screened-in porch area, a storage room, and plenty of dock space to relax and fish. A building right and the fifth-wheel currently on the site convey with this sale. This is a great buy for those looking for a slip - at this comparable price, why buy just a slip in a marina when you can have a buildable lot AND a place to keep your boat and RV? Also a great buy for those looking to build a new, waterfront home down the road who want to live in their RV till then. Community amenities include a boat ramp, laundry room, clubhouse with big TV, pool table, kitchen, etc available for private parties, and an oceanfront pavilion area to take in the open Atlantic views. Boat lifts are allowed. Proximate to grocery stores, shops, restaurants, Sombrero Beach and all things in Keys paradise on the water and on land. There's a lot of bang for your buck ...
