About this home

This is a great opportunity to live in the very desirable Sachem’s Head Association. This cape is perfectly situated on its 1.3-acre lot in a manner which captures an abundance of natural light and incredible views of Sachem’s Head Harbor. The first floor has a spacious living room with high ceilings, wood fireplace, and glass sliders which open to the bluestone patio. The family room/kitchen area has a very open floor plan with wood floors, a fireplace and views to the harbor. Please be aware that the interior condition of the home has changed from the pictures due to a recent water leak. Servpro was hired to properly dry and remove all the effected areas. As such, the foyer, first floor master bedroom, master bath and extra room have all been gutted and are awaiting your upgrades. The second floor has two additional bedrooms, a full bathroom, and attic storage space. The Sachem’s Head Association provides access to beach, tennis, paddle tennis and a boat launch.

Please be aware that the foyer, master bedroom, master bath, and extra room have all been gutted and area awaiting your buyer's upgrades.
