Single Family Home for sale in Mahopac, NY

for $1,495,000 with 3 bedrooms and 2 full baths. This 2,737 square foot home was built in 1825 on a lot size of 3.13.

Half Moon Farm delivers an idyllic Hudson Valley escape just one hour from Manhattan. Set on over three serene acres, this meticulously updated 19th-century farmhouse seamlessly connects historic authenticity with modern luxury for buyers seeking a private country retreat or turnkey farm property. Originally built in the early 1800s, the historically registered three-bedroom, two-bathroom residence features restored original wood floors, light-filled interiors, and classic architectural proportions. A welcoming entry opens to a sunlit living room with a wood-burning fireplace, custom built-ins, and a quiet reading nook. Double doors lead directly to a covered patio framed by climbing grapevines and honeysuckle that invites hummingbirds into the surrounding organic herb and flower gardens. The property offers established plantings of rosemary, oregano, thyme, basil, lavender, dill, chives, sage, and lemon balm set alongside roses and butterfly bushes with rich, organically maintained soil. The kitchen pairs rustic charm with modern efficiency, featuring butcher block countertops, custom cabinetry, stainless steel appliances, and an expansive pantry with exceptional storage. A finished lower level adds flexible living space with radiant heated floors, a recreation area, and direct walkout access to the landscaped backyard. Outdoors, mature 200-to-300-year-old maple trees and historic stonework surround a secluded bluestone saltwater pool set within a former sheep paddock. The grounds double as a thriving natural sanctuary frequently visited by native wildlife, including eagles, screech owls, rabbits, indigenous tortoises, and wild turkeys. Auxiliary structures like a sizable garden shed and flexible acreage provide prime potential for future guest cottages or secondary outbuildings. Located moments from the Sedgewood Club beachfront and golf course, Half Moon Farm represents an opportunity to own an eco-conscious Hudson Valley retreat within convenient commuting distance of New York City.
