21 Blackwater St, Santa Rosa Beach, FL 32459

21 Blackwater Street presents a rare opportunity to own one of 30A's most compelling waterfront residences--offered at an extraordinary value, approximately $800,000 below appraised value. Spanning 4,563 square feet across three thoughtfully designed levels, this six-bedroom, five-and-a-half-bathroom home blends refined architecture, sophisticated interiors, and an unparalleled connection to the natural beauty that defines the Emerald Coast. From the moment you enter, a rich blend of maple and walnut cherry hardwood flooring, a striking glass-railed staircase, and expansive lake views establish a sense of understated elegance. The main living area is anchored by custom built-ins and framed by windows that capture the ever-changing scenery of Western Lake. Designed for both entertaining and everyday living, the chef's kitchen features an oversized island, a Viking range, built-in coffee system, premium Liebherr refrigerator, and generous gathering spaces that flow seamlessly to multiple porches overlooking the water. The second-floor primary suite offers a private retreat with its own balcony, dual walk-in closets complete with custom cabinetry, a dedicated makeup vanity, and a spa-inspired bath featuring a soaking tub and separate shower room. Additional accommodations include spacious guest suites, a custom bunk room, a media room with built-ins, and a fitness room with wet bar, creating exceptional flexibility for hosting family and friends. Outdoor living is equally impressive. An intimate courtyard centered around a fireplace and fountain invites relaxed evenings beneath the stars, while oversized screened porches provide front-row views of one of South Walton's most treasured coastal dune lakes. A two-car garage, abundant storage, and carefully curated design details throughout enhance both comfort and functionality. Just moments from WaterColor's celebrated amenities--including resort-style pools, nature trails, parks, and access to the Gulf--and within easy walking, biking, or golf cart distance of Seaside, acclaimed dining, boutique shopping, and the sugar-white beaches of 30A, this residence embodies the effortless luxury and coastal lifestyle for which the community is renowned. Short-term rentals are permitted, further enhancing the property's versatility and investment potential.
