Serenity Found. Beautifully updated waterfront living on one of the most desirable locations in Bel Marin Keys, offering expansive lagoon views and a rare sheltered setting. Thoughtfully refreshed inside and out, this 4 bedroom, 3 full bathroom home blends modern comfort with the relaxed waterfront lifestyle that makes BMK so special. The flexible floor plan includes a desirable main-level bedroom and full bathroom, ideal for guests, multigenerational living, or a private office setup. Upstairs, the expansive primary suite offers a true retreat with room for a sitting area, home office, or lounge space overlooking the water, complemented by a beautifully refreshed en suite bath with a calm, coastal-inspired feel. Downstairs, immaculate walnut floors have been recently refinished, while oversized dual-pane sliders create seamless indoor-outdoor flow throughout the main living spaces. The updated kitchen features new cabinetry, countertops, sink, and select newer appliances, all thoughtfully integrated into the home's open and functional design. Outside, the newer multi-tier Trex deck with custom stainless steel wire railings creates the perfect setting for entertaining, while the separate fire pit patio invites quiet evenings by the water. The low-maintenance, drought-conscious landscaping in both the front and rear yards, turf lawn, striking palm tree, private boat dock with lift, and expansive waterfrontage complete the resort-like outdoor setting. Additional improvements include newer dual-pane windows, a Tesla charger, and new insulation throughout the attic and sub-area. Everyday life feels elevated on the water in Bel Marin Keys, where residents enjoy boating, kayaking, paddleboarding, tubing, wakeboarding, swimming, and direct access through the neighborhood lock system to the San Pablo Bay and Petaluma River. A rare opportunity to experience one of Novato's most unique waterfront communities. Peaceful by nature. Stunning by design.
