Welcome to one of the best values currently available in the Florida Keys. Located in the private gated community of Stirrup Key, 199 Stirrup Key Blvd delivers newly completed luxury construction, over 3,400 square feet of living space, a heated resort-style pool, and immediate open-water boating access — all offered at $2,197,000. For buyers searching for a new construction home in Marathon with both space and quality, this property stands apart as the lowest priced new construction pool home over 2,500 sqft by more than $600,000.

Built by respected local builder Design Center, this modern coastal residence was designed for full-time living, second-home comfort, and long-term durability in the Florida Keys climate. The home features 5 bedrooms, 5 full baths, concrete block construction, impact windows and doors, a metal roof, EV charging pre-wire, multiple water-view balconies, and designer interior finishes throughout. The heated custom pool, oversized driveway, garage, and additional space for boat trailer or RV parking create a level of functionality rarely found in new construction homes in Marathon.

Unlike many areas of the Keys dominated by short-term vacation rentals, Stirrup Key offers a more private residential setting with no weekly rentals allowed. Residents enjoy gated entry, a private community boat ramp, and quick access to open water, making this an exceptional opportunity for buyers seeking luxury, privacy, boating access, and long-term value in the heart of the Florida Keys.
