About this property

$375,000 IN INSTANT EQUITY ON A DUCK KEY DEEPWATER ESTATE - 123 FEET OF DOCKAGE, 10-FOOT DRAFT, OPEN WATER. BUY-NOW $5,100,500. ARV $5,400,000. SELLER FINANCING AVAILABLE. You are getting it at $5,100,500 - with the deepest, longest private dockage of virtually any Middle Keys home at this price point. 123 feet of concrete dockage with a 10-foot draft on the open waters of Lake Lucille, Duck Key. That draft is the scarce asset - it accommodates a serious sportfisher or motor yacht that simply cannot get into most Keys canal properties. Dockage of this depth and length rarely trades in the Middle Keys, and it is what supports both the resale and the luxury-rental exit. PROPERTY HIGHLIGHTS 4,762 sqft, 5 bedrooms, 3 full baths + 1 half bath, built 1993, 0.55 acre gated parcel Concrete block (CBS) construction on pilings, tile roof, impact-resistant windows and doors Private resort-style pool, large heated spa, waterfall, covered cabana bar and exterior bath Travertine marble throughout, chef's kitchen with granite, wet bar, wine cooler, fireplace Two dramatic living areas, main-level primary suite opening to the pool deck Two-car garage plus massive lower-level storage Outdoor kitchen, built-in grill, gazebo, hot tub, privacy fencing, security system Open water views; rentals allowed per MLS data Zoning: IS (Improved Subdivision). 2025 taxes: $28,216 THE NUMBERS Asking (Starting Price): $5,050,000 Buy-Now: $5,100,500 ARV: $5,400,000 Estimated Reno: $0 - $10,000 - TURN-KEY.

EXIT STRATEGIES Cosmetic refresh and resale at ARV - the retail buyer pool for deepwater Duck Key estates is thin but well-capitalized Luxury long-term rental (Zillow Rent Zestimate: $7,561/mo) or high-end seasonal/vacation rental - rentals are allowed Hold as a trophy asset: 123 feet of 10-foot-draft dockage is functionally irreplaceable in this market Take it down on seller-financed terms and hold, wrap, or resell after seasoning Phone: Property is being sold AS-IS, WHERE-IS.

All offers require a $5,000 non-refundable earnest money deposit and an average 7-14 day close of escrow. Equal Opportunity Housing. Broker participation welcome at 3% on top of the buy-now price.
