Single Family Home for sale in Dennis, MA

for $3,500,000 with 5 bedrooms and 3 full baths. This 1,854 square foot home was built in 1940 on a lot size of 0.18.

Is this a dream, or have you been here before? Up early before the others, the house is quiet and with a hot cup of coffee in hand, you step outside onto the cool grass and take in the expansive view of Nantucket Sound as the sun comes up over this classic, circa 1940, beach house. Impeccably kept, this coveted property on the bluff evokes memories of Cape Cod summers past while delivering the perfect backdrop for your family’s future. The exterior has been renovated with new roof, siding, and Azek trim. Inside the main level offers an open living room, kitchen, and dining room area with rich wood, tile, and carpeted floors accenting the lighter walls and beamed wood ceilings plus a family room and bath. Upstairs are five bedrooms and two full baths. Nearly every window on each floor frames an everchanging view of the ocean. Walk down the new stairs to the private deeded beach. One visit and you will remember. This is your home.
