Description

One-of-a-kind house boat/barge, wonderfully situated on Narrow Bay. You have to see it in person to fully understand how awesome it is. Taxes are incredibly low at just $665 per year! Approx. 1200 sq ft of living space. Comes with a .18 acre lot with a large driveway, storage, a deck for entertaining, and a composite bulkhead and dock. A water enthusiast’s dream come true. 2 bedrooms and 1 full bathroom, full kitchen, spacious living/dining area, plus a separate lounging area at the main entrance which is perfect for guests. Step right outside of your kitchen onto your balcony and enjoy a morning cup of coffee, a delicious cigar or a romantic dinner hovering over the water with gorgeous views of the bay. Updated electrical service, central air, propane heat and gas cooking, and beautiful custom windows (3 years young) with electronically controlled shades. It has everything you need to live comfortably ON the water, quite literally. Get in just in time for Brookhaven Town’s planned and approved Downtown Revitalization Project scheduled to begin construction soon, just about a half mile away.
