Wayne Gretzky bought a Florida mansion from son-in-law Dustin Johnson for $4.5 million in 2022; four years later, he sold it for $6.42 million

Wayne Gretzky and his wife, Janet, sold their Harbour Isles waterfront home in Florida on June 1, 2026, for $6.42 million. Gretzky had bought the 7,169-square-foot house from his son-in-law, golfer Dustin Johnson, for $4.5 million in 2022. That is a gain of roughly $1.9 million on paper. The road there was rougher than the number suggests. The home first listed at $8.99 million in November 2025, dropped to $7.8 million, and still closed more than $1 million below that.How Gretzky made about $1.9 million on a house he bought from Dustin JohnsonThe purchase happened in March 2022. It was an off-market deal, which means the house never went through a public listing. Gretzky paid $4.5 million, or about $628 per square foot. When the home sold this year, the price worked out to roughly $895 per square foot. That is an increase of about 43 percent in four years.The longer view is just as interesting. Records show the house last sold in 2016 for $2.9 million. So in a decade it went from $2.9 million to $6.42 million, more than double. The home sits on 0.34 acres, and the building has stayed the same size throughout. What changed was South Florida. Palm Beach County's waterfront market ran hot for years, and Gretzky owned the house through most of that run.One caution on the "gain." It is the gap between two sale prices, not profit. Commissions, closing costs, taxes, insurance and upkeep on a large waterfront property all take a bite. The final take-home figure is lower, though no one outside the family knows by how much.Why the asking price fell by $2.57 millionLook at the November 2025 asking price again. At $8.99 million, the Gretzkys wanted almost exactly double what they paid. That is a bold opening bid, even in a strong market. Sellers of high-end homes often start high to leave room to negotiate, and sometimes it works. Here, it didn't.The price came down to $7.8 million, then the final deal landed at $6.42 million. That is $1.38 million under the last asking price, or nearly 18 percent. Measured against the first ask, the total drop was about 29 percent.Buyers in this price range tend to know what comparable homes are fetching. A house at $895 per square foot has to compete with every other waterfront option in the area. One example is a four-bedroom home down the same street, 788 Harbour Isles Place. It was listed in August 2026 at $5.595 million, or about $1,192 per square foot, for a smaller house of 4,693 square feet. That asking price had not been tested by a sale at the time of writing, so it proves little on its own. Still, it shows how widely prices vary inside one small community.What the Harbour Isles address gets a buyerHarbour Isles is a gated waterfront community in North Palm Beach. Some public records label the Gretzky property as West Palm Beach, which is why you will see both names in coverage. The neighborhood covers about 76 acres and is known for Mediterranean-style estates built between 2000 and 2004. One listing describes fewer than 100 homes and a manned gate.Boating is the main draw. Listings for the community advertise deep-water docks and ocean access with no fixed bridges, so a yacht can reach open water without waiting on a drawbridge. Prices across the community have ranged from $475,000 for the smallest units to $8.75 million for the priciest houses on one brokerage's site. A rare pair of adjoining homes on Harbour Isles Court was recently offered together at $19.95 million.That range explains the Gretzky result. Buyers here are not buying a generic mansion. They are buying a specific lot, a specific dock and a specific stretch of water. The Gretzky lot is 0.34 acres, which is modest by the standards of Florida estates. Buyers pay a premium for frontage and dock space, and not every house in the neighborhood has the same amount of either.How the sale fits Gretzky's long history with real estateThis is not the first time the Gretzkys have turned a property into a decent return. They bought a home at Sherwood Country Club in Los Angeles in 2009 for $2.765 million and later sold it for $6 million. Gretzky's family foundation also bought a townhouse in Palm Beach Gardens for $1.58 million in October 2021, a few months before the Harbour Isles deal.Family ties run through the Florida market, too. Johnson and Paulina Gretzky, Wayne's daughter, sold their own Palm Beach Gardens estate for a reported $16.5 million after buying it for about $5 million in 2015. Johnson and Paulina share two sons, Tatum and River.Gretzky has also been linked to homes in McCall, Idaho, and his childhood hometown of Brantford, Ontario. Whether the Harbour Isles sale signals a change in his Florida plans has not been stated. What the numbers do show is a family that has bought carefully, held for years, and sold into a market that was willing to pay.Stay updated with the latest Asian Games 2026 news, check the Asian Games medal tally and complete Asian Games schedule.Get the latest Sports News and Live updates.
