About this home
Exceptional Investment Opportunity! Welcome to 512-516 Voorhees Avenue, a spacious side-by-side duplex offering two well-proportioned 3-bedroom, 1-bath units in an established Middlesex neighborhood. Each residence features a bright living room, formal dining room, functional kitchen, generously sized bedrooms and hardwood flooring throughout much of the living space. Separate basement areas provide substantial utility and storage space, while the covered front porch, rear screened porch, expansive driveway and large backyard add everyday convenience. Both units are occupied by long-term tenants currently paying below-market rents, creating meaningful future income and value-add potential. Utilities are separate and each tenant pays all utility cost including lawn maintenance for their respective sides. Owner pays taxes & insurance. The property requires updating and is being offered strictly as-is, with the price reflecting its present condition. An excellent option for investors seeking to expand their portfolio or an owner-occupant looking to live in one unit while generating rental income from the other. Conveniently situated near community open space, local schools, parks, shopping, dining, public transportation, Dunellen Train Station and major roadways including Routes 28 and 22 and Interstate 287. A rare opportunity to acquire a substantial two-family property with each unit providing a good amount of living space and significant long-term upside.
