This long-term tenant adds significant value to the property, making it an ideal choice for buyers seeking a low-maintenance investment with immediate returns. The space is well-maintained and professionally operated. A full basement, easily accessed through the building's main hallway, provides a large windowed office area, and separate storage space, along with access to the building's entrance to the backyard.  11-foot lobby ceilings usher you into the two residential units of the building. Each unit provides almost 1,000 sq. ft. of living space, 2- & 3-bedroom layouts, with open kitchens, separate dining areas, walk-in closets, and 1 bathroom. Hardwood floors run throughout, and handsome woodwork frames the windows and doorways. All units are updated with split A/C units. 9 1/2-foot ceilings on the second floor, and almost 9-foot ceilings on the third floor, along with oversized windows, offer picturesque views of 10th Avenue from the front of the building & expansive New York Harbor views in the back of the building. Keep the rental units as is, or update to maximize monthly income. The 2nd floor residential unit is currently rented below market value, with a lease extending through December 2026.
