About this home
Exceptional six-family investment opportunity just steps from Kendall Square. This well-maintained three-story building features two units per floor. The two ground-level units offer private entrances, while the upper-level units are accessed via shared entrances—one for the left-side units on the second and third floors, and one for the right side. Four units (on the ground and second floors) include 2 bedrooms and 1 bathroom, while the two top-floor units feature 3 bedrooms and 1 bathroom. The property has been professionally managed, and all units are in excellent condition. Strong rental income with a cap rate above 5%. Flexible ownership options: occupy one unit and rent the others or operate all six as income-generating rentals. All current leases end on Aug 31, 2026. A full basement with over 1,800 square feet offers significant potential for additional use or future finishing. See attached interactive floor plans and 3D tour for a detailed view of the property.
