John Salley, who helped the Detroit Pistons earn the nickname 'NBA Bad Boys' in the late 80s says selling his 62-room Detroit mansion was his biggest real-estate mistake.

In 1995, Salley sold the massive home for about $900,000. Today the asking price for the 32,000-square-foot mansion is nearly $9 million.

We've included pictures of the home below.

A Long, Rich History in Detroit

The home - known as the Bishop Mansion - has a long, storied history in the Motor City. The massive home in Detroit's posh Palmer Woods neighborhood was built roughly a century ago for the Archdiocese of Detroit. It's considered one of the most significant homes in the area, built for the Fisher Brothers for Bishop Michael Gallagher of the Roman Catholic Archdiocese in the 1920s.

Today, the home could use a little work. Although some renovations have taken place, there are many opportunities for improvements in this home. Is that code for 'Fixer-Upper?' Take a look at the pictures below and you'll see what we mean.

John Salley's Party Pad

Salley joined the Detroit Pistons in 1986, fresh out of Georgia Tech. The 6 ft. 11 in. superstar says in this video that he waited a few years before buying the mansion from the Catholic Church for about $500,000. Stevie Wonder had previously made an offer on the house but ultimately didn't buy it.

During the years that he owned it, Salley says he had various family members living in the home with him and threw lots of parties that were attended by a host of celebrities including Janet Jackson.

Today, the home shows some signs of wear. It features 12 bedrooms, 11 bathrooms, and a stunning entryway. Parts of the home are beautiful while some rooms have been stripped down to the studs.
