Under contract-accepting backup offers. One or more photo(s) has been virtually staged. Properties like this do not come to market. They are passed down. Set on nearly 4 acres with 200 feet of pristine Rainbow River frontage, this is one of the largest and most significant privately held lots on the entire river. Located at the widest section just upriver from KP Hole, the property features its own private dive spring right off the backyard, gushing crystal-clear water year-round. Across the river sits 1,459 acres of preserved state park land, ensuring your view will never be anything but trees, wildlife, and water. The existing 3,200-square-foot residence is packed with 1974 character and massive potential. It features a sunken living room with vaulted ceilings, a massive kitchen with a step-down utility room ready for expansion, and four bedrooms split between the floors. Upstairs, a spectacular primary suite is reached via a winding spiral staircase and features a private porch and a two-story wall of windows framing the river view. Jack-and-jill bathrooms serve both levels, plus a convenient half-bath accessible from the outside for river days. Currently operating as a highly successful vacation rental that sleeps up to 20, the property is being sold fully furnished (furnishings negotiable). But the real value here is the canvas. The high, dry land sits outside the 100-year floodplain and carries two addresses on a single nearly 4-acre parcel. There is room to expand the current footprint, build an entirely new secondary residence, or execute a visionary gut renovation to create the ultimate luxury primary home. A new roof was installed in 2024. The property also retains a grandfathered dock footprint on the river, an increasingly rare asset. This is not just a house. It is a legacy holding on one of Florida's most beautiful natural waterways.
