Exceptional owner-user opportunity in the heart of Smithtown! This well-maintained 1,683 SF professional office building is situated on a 10,890 SF lot with NB (Neighborhood Business) zoning. The first floor is ideal for an owner-occupant, while the income-producing lower-level tenant provides immediate rental income to help offset ownership costs. Conveniently located on Terry Road with easy access to major roadways, shopping, restaurants, and the Smithtown business district. A great opportunity for professional, medical, or service-related businesses seeking to own rather than lease, while benefiting from an existing income stream.
