646 Teaneck Road Rare opportunity on an oversized 15, 625 SF corner lot in a central Teaneck location. This spacious home offers over 4, 000 SF of living space, not including the basement, with a flexible layout and tremendous potential. The second floor features 4 bedrooms and 2 full baths, including a primary bedroom with its own private bath. The main level offers a living room, dining room, den, and an additional room with a full bath, ideal for guests, extended living, or private work space. A standout feature is the attached professional/dental office space with a separate entrance, creating a unique opportunity for a doctor, dentist, or other professional to have a private office/clinic setup connected to the home. Alternatively, this space may be incorporated back into the main residence or reimagined as an additional guest/extended-living suite, subject to municipal approvals and buyer due diligence. The oversized lot and lower driveway/garage area also offer potential to redesign the outdoor space and create a more private backyard setting away from the main road. A rare combination of size, flexibility, visibility, and upside in Teaneck.
