Rare opportunity to own a beautifully maintained legal two-family home in Lake Peekskill, Putnam Valley, offering income potential, flexible living arrangements, and sweeping year-round views of Junior Lake. Whether you're looking for an income-producing property, a home with a legal accessory apartment, a mortgage-offset opportunity, or flexible multi-generational living, this versatile property offers exceptional possibilities in a desirable Hudson Valley lake community. The main residence features a bright, thoughtfully designed floor plan with a formal dining room accented by a custom wood ceiling, an updated eat-in kitchen with refreshed cabinetry, stainless steel appliances, breakfast bar seating, tile flooring, and a sunny breakfast nook. The spacious living room features a picturesque bay window framing sweeping year-round Junior Lake views, while the primary suite offers a renovated ensuite bath, complemented by additional bedrooms and a second full bath. The legal lower-level apartment offers two private entrances, a living room, bedroom, renovated full bath, and direct access to an expansive brand-new deck overlooking the backyard and Junior Lake. The apartment was recently used for extended family, so the stove and refrigerator were removed and the interior door separating the apartment from the main residence will need to be reinstalled to restore its original configuration. Existing kitchen cabinetry and plumbing remain in place, making it easy for the next owner to reinstall the appliances and return the apartment to its intended use. The outdoor spaces are equally inviting, with beautifully maintained perennial gardens, mature landscaping, seasonal blooms, and private areas for outdoor dining, entertaining, and relaxing. Recent improvements include a new septic tank, removal of the underground oil tank, energy-efficient ductless air conditioning on both levels, and a heat pump incorporated into the home's HVAC system, and brand new deck. Enjoy Lake Peekskill lake rights, including swimming, fishing, kayaking, and non-motorized boating. Conveniently located near the Taconic State Parkway, Route 6, Metro-North, shopping, dining, and the many recreational opportunities throughout the Hudson Valley. Legal two-family living, lake community amenities, Junior Lake views, income potential, and a flexible lower-level apartment make this a unique opportunity in Putnam Valley. With the recent price improvement, this is an excellent opportunity for buyers seeking versatility, value, and the lifestyle of a Hudson Valley lake community.
