Description

This extraordinary Mid-Century modern single-family home is a private tropical oasis at the (rarely available) end of a canal with direct-ocean access. The luxury resort-style patio features Travertine tile, a heated pool with a sun shelf, and custom landscape lighting for evening entertaining. The home's original craftsmanship is high-lighted by tongue and groove Florida Pine ceilings, grand archways, and wooden beams. The floor to ceiling windows and doors provide for natural light flowing into the home from sunrise until sunset. The open-concept living area connects to an updated kitchen with stainless steel appliances and granite countertops. The master suite boasts a hand-scraped Acacia Hardwood accent wall, barn doors, an oversized Travertine shower, and a floating sink. Two additional bedrooms in a separate wing provide guest privacy with a shared updated bathroom with an Italian marble shower. This oversized fenced lot at 8,362 sq/ft provides a tropical sanctuary in paradise. Whether you're looking for an established and profitable rental property or you're ready to embrace the dream of a Florida Keys lifestyle, this turnkey property delivers.
