This former schoolhouse has plenty of potential. Currently operating as the Double Door Gallery during the summer months, showcasing local and regional artists, the property boasts two large open rooms on the first floor, featuring curved walls, bead board, and wood paneling on the walls and ceiling, along with a convenient half bath. The second floor presents a studio apartment with room for expansion, offering an immediate income-producing opportunity through gallery rentals and potential apartment leasing. Its mid-island location provides easy access to the library, public park and playground, island market, and post office, making it an ideal spot for community engagement. Imagine the possibilities: continue its legacy as a vibrant art gallery or transform it into whatever your imagination can dream up. This property is not just a building; it's a piece of history with a bright future, ready for its next chapter. Lease in place from June 15- September 15 2026.
