Great Cobb Island location less than 1 block from the water, with a view of the Potomac from your front lawn. A great opportunity for an all cash buyer to get a good fixer upper or tear down and build a 2-story home with a great view of the Potomac from the 2nd floor! Property being sold in AS IS condition. This single floor home has a heated Florida/Sun room with plenty of windows, a living room with a brick fireplace, one bedroom and one full bath, kitchen with stove/range and refrigerator, and a rear utility room with an oil fueled furnace, and washer and dryer. Assessed square footage is 708 sf, but our measurements are approximately 861 sf, including heated Florida/Sun room. There is a storage shed out back and an above ground oil tank installed in the last 3-5 years. Highly rated schools! Cobb Island is a unique water oriented community with restaurants, coffee shop/cafe, grocery, post office, modern playground, community activities and more!
