Fully gut-renovated multi-family with permitted 2021 renovation — this property underwent a comprehensive top-to-bottom renovation completed under full permit in 2021, including brand-new boilers, all-new plumbing, and all-new electrical systems throughout. Every kitchen was fully renovated with new cabinetry and new appliances. The property has been professionally managed and well-maintained since renovation. Currently tenant-occupied at will; the first-floor unit will be delivered vacant at closing — ideal for an owner-occupant or investor seeking immediate income with upside. Don't miss this turnkey opportunity in a renovated, low-maintenance asset.
