“Diddy loved it” – John Salley listed the celebs who partied in his 40K square feet mansion in Detroit

John Salley was a pretty big deal in Detroit. As a two-time NBA champion with the Pistons, he had no shortage of fans in the area. However, as popular as he was, his mansion was so huge he could’ve fit all of those fans in.

During his Bad Boy days, Salley bought the historic Bishop Gallagher Mansion (or simply, the Bishop Mansion).

It is a sprawling 40,000-square-foot attraction that practically became a celebrity attraction. Sally rubbed elbows with music and movie icons, so it was only natural for him to show off.

The Mansion’s star-studded guest list

The Bishop Mansion, as its name suggests, was not meant to be a private residence. It was a religious institution built in the 1920s until Salley bought the 62-room property in 1989.

As it transitioned into an individual home, you could bet it became the venue for hundreds of parties, given Salley’s penchant for girls and a good time. Moreover, John was from Brooklyn, New York, so he undoubtedly had celebrity connections, not to mention the fact that he was NBA royalty as a basketball champion.

And with the mansion’s size, you could just imagine how many A-listers and famous people could fit in it on any given night.

“It is the largest home in Michigan,” Salley

“It’s in the only hill that’s in Detroit. (Spike Lee) had his own room. He took a section out of my house when he was interviewing Malcolm X’s family members. He liked coming in because he’s like, ‘Yo, this is bomb.'”

“And Diddy loved my house. He came in and thought it was great. I had Janet Jackson there. I had Bill Bellamy… Martin Lawrence, (the band) Guy, Regina Bell. I had everybody, man, come through,” added Salley.

The list actually went on. The four-time NBA champ hosted Vanessa Williams and her husband, and unwelcome guests lurked around.

Another interesting part of the story was how Salley acquired the mansion and turned it into a private home. According to the former Pistons big man, the property was originally listed for considerably more than he eventually paid. He got it down to $500,000, then spent $250,000 to replace the Italian fabric from the original maker.

Of course, the furniture and the gadgets around the house were just as fascinating. Salley claimed he had a 65-inch TV back then, which wasn’t easy to procure. In the late ’80s and early ’90s, the biggest traditional tube TV on the market had only a 45-inch screen. So Salley may have gotten a 65-inch projection TV that cost $2,500 to $4,000.

Salley had to sell the house

John undoubtedly enjoyed the attention that came with owning such a notable property. However, good things come to an end and Salley’s stay in Motor City ran its course. After six seasons and two titles in Detroit, the franchise traded Salley to Miami. Then, he signed a four-year extension with the Heat and remained in South Beach until 1995.

With how his playing career turned out, Salley had to sell the house. Coincidentally, a religious institution, Great Faith Ministries International, purchased the property for $900,000, almost twice the amount John paid for it in 1989.

Regardless, the Bishop Mansion under Salley’s ownership had a great run. Judging by the names who came through its doors, Salley certainly made the most of his time there.
