21 Flagg Avenue

Property Description

This stylish and sunlit beach retreat is located in the coveted Ditch Plains neighborhood-just steps from the ocean and one of Montauk's most iconic surf spots. With three cozy bedrooms and two full bathrooms, the home is designed for a relaxed coastal lifestyle. The fully equipped kitchen features sleek stainless steel appliances, and the open living room offers a bright, inviting atmosphere with expansive glass walls and a fireplace. In 2025, the home underwent significant upgrades, including a new roof, new skylights, upgraded insulation, a new Bilco door, and improvements to the foundation and crawl space-along with the installation of a dehumidifier system for enhanced comfort and efficiency. After a day at the beach, rinse off in the outdoor shower, then unwind in the private, fenced-in yard-perfect for lounging or outdoor games. A front deck and back patio provide ideal spaces to soak up the sun or enjoy meals al fresco. And with the beach just a short stroll away, there's no need to worry about parking-simply walk out and embrace the Ditch Plains surf and sand.
