Description

STRAIGHT SHOT to deep-water and 10 minutes to Key West. You will love beautiful Geiger Key with world-class angling, boating, and diving right from your own backyard. Offering the fastest track to blue water and offshore fishing in the Lower Keys, this house is 9 houses back from open water! 157 Mars Ln is an elevated, 3 bedroom, 2 full bath canal home with a 45 ft seawall. NO bridges, shallows or mangroves to navigate here. Bright and cheerful with an open floor plan and high ceilings, there is a permitted downstairs enclosure with almost 400 additional sf and a lovely, screened in covered porch overlooking the canal. Indoor/outdoor living is the best! Easy to maintain, over-sized corner lot w/ covered driveway and extra parking for multiple vehicles, boat trailers and an RV. An expansive, covered patio (446 sf) for those warmer days when you need a shady respite is a delightful feature of the home. Lush, manicured landscaping and tidy graveled grounds offer a serene, tropical space with easy upkeep. Outside shower, fish cutting station and room for a pool! Newer metal roof and LOW INSURANCES! Geiger Key is a fabulous neighborhood with a mix of full-time and winter residents. It offers superior boating and a laid back atmosphere. You will love the relaxing, Old Keys lifestyle. The days drift by and life is more simple here, leaving more time to enjoy the outdoors and island vibe. World-famous Geiger Key Marina and Fish Camp is just around the corner for great food, drinks and live music. It's the Lower Keys best kept secret and serene Boca Chica Beach Park is just down the road, perfect for birding, shell collecting and nature walks. This is a great home for a family or second homeowner who dreams of a waterfront getaway in the Keys. Dockage will easily allow for a 32 foot boat and is just nine houses back from open water.

Navigation note: Navigation routes show the shortest mapped path to open water. A vessel taller than the binding bridge clearance may still reach open water via a longer alternate route that we don't currently map. Verify navigability with a local captain or surveyor before relying on it.
