3 Beds ⋅ 4 Baths ⋅ 2156936 MLS
Currently operating as a successful short-term rental, this exceptional St. Johns County property offers a rare blend of privacy, space, energy efficiency, water views, and income-producing potential -- all within the home of Florida's No. 1-ranked school district. Set on a secluded one-acre wooded homesite, the 3,470-square-foot residence is surrounded by mature trees that create a peaceful natural buffer and the feel of a private retreat. Designed for both everyday living and guest flexibility, the home features three bedrooms, four bathrooms, a dedicated office, and two versatile flex rooms that can serve as additional sleeping areas, a media room, home gym, game room, or creative workspace. Inside, soaring 10-foot ceilings, elegant tray details, abundant natural light, and tranquil water views create an inviting atmosphere throughout the home. The thoughtful layout offers multiple gathering areas, giving owners and guests plenty of room to relax, entertain, and enjoy the property's private setting. Energy efficiency is another major advantage, with solar panels helping reduce electric costs to a reported average of approximately $30 per month. That kind of monthly savings can be especially valuable for a full-time residence, vacation home, or income-producing rental. With its spacious floor plan, private wooded setting, water views, coastal location, and current short-term rental use, this property is well-positioned for a buyer seeking a personal retreat, vacation home, or investment opportunity in one of Northeast Florida's most desirable counties.
