15 Guest Street Boston, MA 02135

The NB Fitness Club, a 27,480-square-foot retail condominium at 15 Guest Street in Brighton, MA, is available for acquisition. The facility features an open-plan layout, high ceilings, and a prominent glass facade. Member amenities include dry saunas, well-appointed locker rooms, and a complementary towel service program. The property is leased on a triple net basis to an established fitness operator within the New Balance-anchored Boston Landing district, with on-site parking at the base of the building. The tenant is responsible for taxes, insurance, and maintenance under a full NNN structure, providing passive income with minimal landlord obligations. Positioned alongside the New Balance Global Headquarters, the Auerbach Center, Warrior Ice Arena, and Roadrunner, the property benefits from consistent, diversified foot traffic throughout the week. Surrounded by two professional sports practice facilities, a major indoor track venue, and a growing base of corporate and residential tenants, the space sits in Boston's most active health and wellness corridor. Members have access to the parking garage above, a meaningful amenity for an urban fitness club. The property is steps from the Boston Landing MBTA commuter rail station with direct service to Back Bay and South Station. With contractual rent growth and 14 five-year extension options remaining, 15 Guest Street offers investors a stable, long-term income profile in one of Greater Boston's most active mixed-use submarkets.
