Exceptional investment or multi-generational opportunity in this rare duplex-style two-family home in the heart of walkable Mamaroneck, where comparable properties are increasingly limited. Separate entrances on opposite sides of the home offer enhanced privacy for occupants. Each distinct unit offers three bedrooms and one updated bath, with individually metered utilities including separate heating, central air, and Navien high-efficiency gas tankless water heaters, allowing independent operation and strong income potential. The first floor unit welcomes you with a charming front porch that leads into a bright and spacious living room with gleaming hardwood floors and a cozy wood-burning fireplace. The updated eat-in kitchen boasts granite countertops, beautiful tile backsplash, and stainless steel Beko appliances. The bath is adorned with classic subway tile and a smart vanity. There is direct access to the basement with additional storage space and a Maytag dryer. This unit is occupied by excellent long-term tenants on a month-to-month lease, providing the option for immediate income and flexibility. The sun-filled second-floor unit is vacant and move-in ready, offering its own living room with a wood-burning fireplace, a large eat-in kitchen with Whirlpool stainless steel appliances, and an in-unit stackable Maytag washer and dryer. There is access to a full unfinished attic for additional storage. The home sits on a large, level yard and the back is fully gated providing a wonderful place to gather. A two-car driveway makes parking a breeze but perhaps the most coveted feature is the location. A five-minute walk from the Metro-North train station and access to the vibrant shops, restaurants, and amenities of Mamaroneck Village. This turnkey property is the perfect combination of modern upgrades and a prime suburban-urban lifestyle.
