Hidden gem in historic Hamilton Heights ! This beautiful multi-family townhouse with a one car garage situated on a quiet tree-lined street off Convent Ave was built in 2003 by a private builder, with rock-solid structure and materials. The current owner reconfigured and upgraded the entire building in 2008, making it a 3-family building. Well-designed apartments feature two bedrooms, open kitchen plan, granite bath, and living room. Every dwelling unit is equipped with a compact, super-efficient, wall-hung Italian-made Baxi Luna combination boiler that produces heat and hot water on demand for the unit. These are state of the art modulating boilers that economize on gas usage, and can achieve up to 100% efficiency, especially when combined with the German-made Buderus radiators in the owner's duplex. The owner's duplex occupies the first two floors and contains a guest or in-law suite. The 3rd and 4th floors are two-bedroom floor-through apartments occupied as free-market rentals by excellent occupants who are on month-to-month leases. The building is kept in triple-mint condition. A tranquil back yard has a stone patio, specimen plants, arbor, koi pond and grape vine. A shed at the back provides additional storage/work shop space. With A, B, C, D and 1 train close by, you have a fifteen minute train-ride to midtown. Columbia University and City College are within walking distance. This unique, comfortable-living and very green property is perfect for owner/investor.
