Lost River Homes for Sale in Stuart

Deep-water boating homes on the South Fork. Every home currently for sale in Lost River, Stuart, straight from BeachesMLS and updated throughout the day.

Lost River is a boating enclave in south-west Stuart on the South Fork of the St. Lucie River, made up of gated Lost River Plantation, Lost River Cove, Lost River Bend and Lost River Manors. Homes were mostly built between 2005 and 2010, with large CBS floor plans, three-car garages and pools; some sit directly on the water with private docks and lifts, and others hold slips in a community marina. Check the water depth, the lift capacity and the bridges on the route down the river to the St. Lucie Inlet against your boat. Homes are zoned for Crystal Lake Elementary, Dr. David L. Anderson Middle and Martin County High.

Dockage, Water and the Club at Lost River

In a boating community the dock is worth as much as the house. For every home in Lost River we confirm whether the dockage is private, deeded or a club slip, the length and beam it takes, the water depth at mean low tide, the height and number of bridges on the route to the inlet, the age and condition of the seawall and the dock, and the flood zone and elevation that set the insurance. Where a yacht or country club sits inside the community, we also confirm whether membership comes with the home and what it costs to join and to keep.

Selling a Home in Lost River

Buyers for a home in Lost River compare it with the other homes in the community first and with the rest of Stuart second, so pricing starts from the closed sales inside Lost River that match your home's section, lot, water frontage and dockage, age and renovation. We market to the buyers who ask for Lost River by name, arrange private showings when discretion matters, and prepare the association and club documents buyers will ask for before the first showing.

Lost River: Frequently Asked Questions

How much do homes cost in Lost River?
Homes in Lost River sold at a median of $1,237,000 over the last six months, and the 6 homes for sale today are asking a median of $1,517,500. Prices vary by section, lot and renovation, so we price every home from the closed sales that match it. These figures refresh daily from the MLS.
Is club membership required to buy a home in Lost River?
Membership terms are set by the club and change over time, so we confirm them for the specific home before you offer: whether membership comes with the purchase or is optional, the membership categories, the equity or initiation contribution and any refund terms, annual dues, food and beverage minimums and planned capital assessments. Some South Florida clubs require membership of every homeowner and others offer it separately.
What size boat can I keep at a home in Lost River?
It depends on the dock, the water depth at low tide and the bridges between the home and open water, all of which change from lot to lot in Lost River. We confirm the dock length, the depth at mean low tide and the clearance of every bridge on the route for each home we show, so you know before you offer whether your boat, or the one you plan to buy, will fit.
How long does it take to sell a home in Lost River?
Homes that sold in Lost River over the last six months took 223 days on average to go under contract and closed at 97.1% of the asking price. Homes priced from the community's own recent sales sell faster; the average is pulled up by homes that started too high.
Can I rent out a home in Lost River?
The association and the club decide. Many Stuart communities set a minimum lease term, limit the number of leases a year, require tenant approval, or require an owner to hold the home for a period before leasing. We read the governing documents for the home you are considering and tell you exactly what they allow before you buy.
What is my Lost River home worth?
Request a free valuation and a BreakThru broker builds it from the closed sales inside Lost River that match your home's section, lot and renovation, not from a citywide median. For a listing decision we prepare a full comparative market analysis and a marketing plan built for the buyers who search for Lost River by name.
