Rare mixed-use investment opportunity in Buffalo's Black Rock/Riverside neighborhood! This 4,121 sq ft building offers a first-floor commercial space (office or retail, roughly half the building) paired with a fully renovated, turnkey 5-bedroom, 1-bath apartment above, ideal for an owner-operator who wants to run a business downstairs and live upstairs, or for an investor seeking dual income streams. The commercial space has served as a hair salon, bar, religious gathering space, and general office/retail over the years, proving its flexibility for nearly any use. Upstairs, the spacious 5-bedroom apartment has been cosmetically renovated top to bottom and is move-in ready, with a private back porch for the tenant, a rare perk in this market. Mechanically, the building is well maintained: separate electric and gas meters (one shared water meter), circuit breakers throughout, a 2017 complete roof tear-off, forced air with central A/C (4 years old) on the lower level, and a boiler serving the upper unit. Hot water tanks are 4 years and 1.5 years old, and the plumbing has seen recent supply-line upgrades, with a mix of copper, steel, and PEX. A steel main carrier beam supports the structure, and the exterior features stone and vinyl siding, plus a curb cut and driveway on the left side for easy off-street parking. Location is a major draw: you're minutes from the Niagara River and the Empire State Trail, with downtown Buffalo, Grand Island, and the Town of Tonawanda all about 5 minutes away. The City of Tonawanda, North Tonawanda, Amherst, and Hamburg are also close by, putting nearly all of Erie County within easy reach. Don't miss this chance to own a versatile, income-producing mixed-use property in one of Buffalo's most connected neighborhoods.
