Sunrise, Sunset — Your Beachside Oasis Awaits Wake up to ocean views and wind down with stunning sunsets from your private bedroom balcony in this spacious and versatile beach home. With 5 bedrooms, 3.5 baths, and over 3,350 square feet, this legal two-family duplex offers incredible flexibility — perfect for a large family, multi-generational living, a dedicated guest suite with its own full kitchen, washer, and dryer, or a legal accessory apartment. Inside, enjoy a blend of comfort and style with ceramic flooring on the first level, hardwood upstairs, recessed lighting throughout, and multiple skylights that flood the space with natural light. A rebuilt stone front facade, first layer roof (2012) and emergency generator add both charm and peace of mind. Step outside to a private side patio with a new hot tub, built-in bar refrigerator, and cooler — ideal for entertaining. The expansive deck and patio both feature retractable awnings, and all outdoor furniture is included. And, this is one of the only homes which has a deeded beach to the median high tide water line. This is more than a home — it’s a lifestyle. Whether you're watching the sunrise with your morning coffee or enjoying evening cocktails as the sun sets, this property offers a rare opportunity to live the beach life to the fullest.
