About this home
Situated on a prominent corner lot in Brighton, 4 Union Street presents a compelling multifamily investment opportunity consisting of four spacious duplex residences totaling 12 bedrooms and 7.5 bathrooms across approximately 5,202 square feet of living area. The property generates approximately $180,000 in annual rental and parking income, with leases currently in place through August 31, 2027, providing an incoming investor with immediate and predictable cash flow. Strong historical occupancy and consistent rental demand are supported by the property's proximity to area universities, major employment and medical centers, restaurants, public transportation, and convenient highway access. Each residence offers generous living space, in-unit laundry, and outdoor deck space. Separate utilities provide operational efficiency and limit owner-paid expenses. Off-street parking area accommodates up to eight vehicles, providing an additional source of income in a supply-constrained urban market. With its combination of strong in-place income, desirable unit layouts, extensive parking, and established rental history, 4 Union Street offers investors a well-positioned income-producing asset in one of Boston's most active rental markets.
