They ultimately sold it to tech company CEO Sanjay Shah for $17 million. A mansion in Winnetka also once was available for $32 million, although its owners now are seeking $12.999 million for it. Michael Jordan once sought $28 million for his 56,000-square-foot Highland Park spread, which currently is available for $14.855 million.
