Welcome to 121 Bay Street Extension, Portland's best-kept secret in the Back Cove neighborhood. This end-unit condo is the most private in the association, set quietly against Portland Trails where you'll feel worlds away while still being minutes from everything. Step outside and walk to shops and restaurants along Forest Avenue, Woodford's Corner's cafes and markets, or recreation at Payson Park and Back Cove Trail. Downtown Portland is just 10 minutes away, making this the perfect balance of nature and convenience. Inside, the home is move-in ready with room to make it your own. The first level offers a galley kitchen, half bath, and living/dining room with access to a private brick patio. Upstairs are two generous bedrooms and a full bath, while the top floor is a true retreat with a skylit primary suite featuring cathedral ceilings and ensuite bath. With two off-street parking spaces, remarkably low monthly fees of 275, and a pet-welcoming, well-run association, this is one of the most affordable opportunities in Portland. Priced to sell, we expect strong buyer interest. Showings available immediately, with an open house Sunday, September 21st from 1-3 pm. Offers due Tuesday, September 23rd at 5 pm. Sellers prefer a quick and clean closing.
