Welcome to Sunset Anchorage, a beautifully renovated open-water home in the exclusive gated community of Stirrup Key. Set on an expansive lot and a half, this three-story CBS home offers exceptional privacy, protected dockage, a private pool, and sweeping Gulf views with spectacular sunsets. Thoughtfully updated throughout, the home features a brand-new kitchen with custom cabinetry, custom bar, updated flooring, new impact windows and doors, new A/C units, and Hardie board siding accents. The main level features the primary suite with a newly expanded and completely renovated bath, plus a guest bedroom with marina views and a full bath nearby. An extended covered porch off the living and dining areas overlooks the pool and Gulf. Upstairs, a secondary primary suite offers a private bath and walk-out balcony with stunning open-water views, while an additional guest bedroom and half bath complete the level. Outdoor living includes a spacious covered patio, newly built tiki bar, and beautifully refinished and re-tiled pool with new equipment, heater, and chiller. A redone waterfront observation deck provides easy kayak access and an ideal place to enjoy the sunset. Across the street, protected dockage in Stirrup Key's private marina includes concrete boat slip D41 with a walk-out dock and new 15,000-lb Hurricane Hoist boat lift.
