Situated in the coveted Abbott Tract in historic St. Augustine, this immaculately maintained home offers the rare combination of a private saltwater pool, detached guest villa, and detached 1½-car garage--all just one block from Castillo De San Marcos fort, the Bayfront, and St. Augustine's renowned restaurants, galleries, and boutiques. Built in 1920, the main residence offers 1,963 square feet with three bedrooms and three full baths, including a spacious first-floor owner's suite. Original wood floors, a gas fireplace, crown molding, and a wide covered and screened front porch preserve the home's timeless character, while impact-resistant windows, a metal roof, and fresh interior and exterior paint provide modern comfort and peace of mind. The light-filled kitchen features white cabinetry, stainless steel appliances, and a distinctive blue tile backsplash. Upstairs offers a cozy office or reading area, full bath and separate guest quarters. Just beyond the main home, the detached poolside guest suite (deemed the Villa) with a full bath creates a flexible fourth bedroom and fourth bath--ideal for visiting guests, a private office, studio, or independent retreat. Outdoor living is centered around the screen-enclosed saltwater pool with built-in spa seating, complemented by mature landscaping, a spacious and private fenced backyard, and a gas fire-pit for relaxed evenings and entertaining. Additional highlights include an extended paver driveway with valuable off-street parking and RS-2 zoning that allows for short-term rental use, offering flexibility for both personal enjoyment and income potential. The property is offered with or without the adjoining buildable lot at 45 Osceola Street, creating the opportunity for additional privacy, future development, expanded grounds, or a one-of-a-kind private compound in one of St. Augustine's most desirable neighborhoods.
