Rare opportunity in Mastic Beach. Fully renovated Cape on a private 1+ acre corner lot with river views, modern upgrades throughout, and flexible living space including a possible 4th bedroom or office.
Welcome to 4 Riverside Avenue, a beautifully updated home that offers the perfect combination of space, privacy, and modern comfort. This property stands out with its oversized lot, thoughtful renovation, and peaceful natural surroundings.
