Raised in Buffalo Grove and then Lake Forest, Vaughn owned the top three floors in the Palmolive — the 35th, 36th and 37th — from 2006 until 2016. He paid $12 million in one deal for all three floors, but he ultimately sold the triplex in two pieces in 2016, unloading the top two floors for $8 million and then selling the 35th-floor unit for $4.1 million.
