About this property
Originally the Engine No. 8 Firehouse, 133 Salem St has been thoughtfully reimagined into a stunning 4-unit mixed-use property where history and opportunity meet. Fully renovated to a high standard in 2013, it offers a rare chance for an owner-occupant to live in a piece of Boston’s past while enjoying strong, stable income. The 2,400+ sq. ft. ground-floor commercial space leased to the well-established BTONE Pilates Studio anchors the property with reliable cash flow. Above, 3 beautifully finished residential units provide flexibility to live, rent, or reconfigure to suit your vision. The 3+ bedroom penthouse w/ private outdoor space and sweeping views is ideal for a primary residence, with additional income from the other 2 leased units to offset ownership costs. Down the street from the Eliot school and all the other outstanding things the North End has to offer, this turnkey asset combines long-term investment security with everyday lifestyle appeal.
