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.

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.
