Welcome to 423 Allen Avenue, a surprisingly spacious Portland home offering two bedrooms, one-and-a-half baths, plus an additional room currently used as a third bedroom. The expansive living room stretches across nearly the entire rear of the home, where full-length windows bring in abundant natural light and overlook beautiful backyard gardens. Skylights add even more natural light, helping create a bright, open feel throughout the home. A ramped back side-door entry provides added convenience, while the mostly fenced backyard offers privacy and room to enjoy the outdoors. Ample off-street parking provides added convenience, and a small outdoor shed offers handy storage for gardening tools and lawn equipment. Inside, the full basement provides plenty of additional storage. The home is heated by oil-fired forced hot water, and recent improvements include updated GFCI outlets in the kitchen and plumbing updates in the main bathroom. Enjoy a convenient Portland location close to shopping, dining and everyday amenities, the Portland Trails network, and nearby river access for kayaking, canoeing and fishing. The seller is offering a contribution toward allowable closing prepaids, and/or other concessions. Open house 9/13/26 Sunday.
