A rare opportunity to have one of the original vintage cottages, situated in a stand of tall pines, in Tall Timbers on the Potomac River. The house needs some updating but the lot and setting and western view are the main attraction. A different sunset every night! There are 3 bedrooms on the upper level with an old fashioned “sleeping porch” overlooking the water. An inviting screen porch wraps 2 sides of the waterfront, perfect for eating crabs, enjoying a good book or just taking in the view across the river, all the way to Virginia and St. Clements Island where the first MD settlers landed. The waterfront features an over-sized, 2 level pier with built in bench seating and a sink for cleaning fish. The detached 2 car garage offers plenty of overhead storage plus a separate outdoor shower.
