Aim high? No. 9 Walton condo owners looking to flip full-floor unit for a nearly 40% profit

Two months after buying an $8.2 million unit in the No. 9 Walton luxury condo building, a couple is looking to sell it for $13 million — a profit of nearly 40 percent.

Jeffrey and Linda Wolfson closed on the full-floor unit on the 33rd floor of the building at 9 West Walton Street in the Gold Coast in November, and now are putting it on the market, according to Crain’s.

Listing agent Nancy Tassone of Jameson Sotheby’s International Realty told Crain’s the markup on the partially finished 7,100-square-foot unit reflects the Wolfsons buying it at “a 2014 price,” before the building from JDL Development became one of the hottest Downtown luxury properties.

Jeffrey Wolfson in 2012 settled a case with the Securities and Exchange Commission, after he and his brother were accused of making millions of dollars in illegal short sales while he was a trader on the Chicago Board of Options Exchange.

Documents for the No. 9 Walton purchase listed the couple’s residence in another Gold Coast condo on East Delaware Street. The Wolfsons sold an 11,000-square-foot home in Glencoe for $7 million in 2014, Crain’s reported at the time. [Crain’s] —John O’Brien
