Property Description
Located in Marathon's desirable Sombrero area, this waterfront home combines immediate boating access, thoughtfully designed outdoor living, and close proximity to Sombrero Beach. The property offers 76 feet of waterfront, a 40-foot dock, and immediate access to open water--an ideal setup for fishing, diving, or simply enjoying life on the water. When you're not on the boat, Sombrero Beach is just moments away. Recent improvements totaling more than $300,000 have transformed the outdoor spaces into an extension of the home. A custom pool and spa with sun shelf, travertine decking, outdoor grilling and bar area, updated landscaping, extensive landscape lighting, multiple covered and screened patios, and a metal roof installed in 2021 are among the property's notable upgrades. A climate controlled 500-square-foot lower-level bonus area provides additional flexible space for storage, recreation, hobbies, or a home gym. The property has also proven itself as a successful vacation rental, consistently generating gross rental income in excess of $100,000 annually. Adding to its appeal, the assumable flood insurance policy is currently just $1,289 per year. Immediate boating access, close proximity to Sombrero Beach, thoughtfully designed outdoor living, and a proven rental history come together in a property that offers the best of Keys living.
