Back on market due to financing. Welcome to 155 Allen Avenue, located in the Deering Neighborhood of Portland. This colonial-style side-by-side duplex in Portland offers a fantastic opportunity for both owner-occupants and investors. Each unit features 3 bedrooms, separate driveways, individual electrical meters, and separate heat pumps. The owner's unit (#155) has been freshly updated with new carpet and interior paint and is move-in ready. The tenant-occupied unit (#153) has undergone extensive improvements including new windows, roof sheathing and shingles, a new deck, and an updated kitchen. Additional upgrades include a hot water heater servicing both units (connected to #153's electrical), new circuit breaker boxes with updated cables to meters, as well as new outlets, switches, and lighting in unit #153. The seller also removed large trees in the backyard, improved drainage and added loam and seed to create a spacious, open outdoor area. Unit #155 also features a new tub surround in the bathroom. Located near Casco Bay High School/PATHS and a short drive to Lyseth Elementary and Lyman Moore Middle School, this property is conveniently within a short drive of the Old Port, Arts District, and the Maine Mall. Whether you're looking for a place to call home with rental income or a full investment property, this duplex offers excellent versatility and potential. There may be potential to expand into the third floor of each unit with the appropriate permits. The owner's unit is easy to show, while the tenant's unit requires 24-hour notice. Inspection report available upon request. Open house on Saturday, May 10 from 11:00 AM to 1:00 PM.
