A listing on the real estate site Zillow had claimed that the Palm Beach, Florida, club had been sold on 4 August to a company called Mar-a-Lago Inc.
Reports suggested that the company was controlled by Donald Trump Jr.
However, that was angrily denied by Eric Trump in a social media post on Friday.
“This is pure FAKE NEWS and Zillow has corrected their listing. Mar-a-Lago has not been sold or transferred in any regard. This story is total BS.”
In a separate statement, Eric Trump said: “Mar-a-Lago has absolutely not been sold nor will it ever be. This rumour is asinine.”
The Zillow listing was updated to show the 5,061-squre foot property with 58 bedrooms at 1100 S Ocean Boulevard in Palm Beach was “off market”.
A Zillow spokesperson told The Independent: “Zillow strives for accuracy on our site and if we become aware of inaccurate information, we will update it immediately.
“After an investigation, it appears that the information provided was incorrect. We’ve corrected the information on this property.”
It’s understood that Mar-a-Lago had been listed for sale on a separate real estate website, and the incorrect data was automatically pulled through onto Zillow.
Donald Trump was booked into the Fulton County Jail in Atlanta on Thursday on 13 felony counts stemming from his alleged efforts to overturn Georgia’s 2020 presidential election results.
He immediately began using his booking mugshot to raise money for his numerous legal woes.
T-shirts featuring Mr Trump’s scowling gaze along with the words ‘Never Surrender” went on sale for a donation of $47 within 90 minutes of him surrendering on charges of election interference.
Coffee mugs, bumper stickers and fabric can holders were also available.
The former president purchased the property for $2m in 1985 and opened it as a private club 10 years later.
After losing the 2020 presidential election to Joe Biden, it became his primary residence.
Mr Trump has been charged with unlawfully retaining classified documents at the club, one of four criminal prosecutions he is currently facing.
