***OPEN HOUSE CANCELED***Tucked away on a quiet dead-end street in one of South Harwich's most sought-after coastal neighborhoods, less than half a mile from Red River Beach, 1 Sea Pine Knoll offers the Cape Cod lifestyle buyers dream about, with several major systems updated. This lovingly maintained, one-owner 3-bedroom, 2.5-bath home had these updates: a brand-new 3-bedroom septic system, a 2021 furnace paired with a tankless on-demand water heater, and central air conditioning for year-round comfort and true move-in-ready peace of mind, with the ability to make it your own. The open first floor is made for gathering, anchored by a centrally located wood-burning fireplace and a classic Morsø cast-iron wood stove that adds warmth and character in equal measure. Freshly refinished wide-plank pine floors, a newly painted interior and exterior, a skylight, and three sets of sliding glass doors fill the home with natural light and open onto the expansive wraparound deck with built-in seating -- private, peaceful, and framed by woods. Brand-new flooring runs through the kitchen, the downstairs bath, and the entire second floor, while the under-house garage and full basement with laundry hookups add generous space for vehicles, hobbies, and beach-house storage. Stroll to the beach past the herring run, bike the quiet neighborhood streets, or venture out to nearby restaurants, shopping, golf, marinas, and conservation lands. A private setting, an unbeatable location, and several major updates behind you -- the rare Cape retreat you can simply move into and start enjoying.
