The cozy mansion fulfills almost every buyer's desire - with a luxurious master suite with wet bar and spa bath, a home gym, putting green, pool, half-size basketball court, and a one-bedroom junior suite.
Williams, a former NBA player, coached the Suns to the NBA Finals in 2021, when they lost to the Milwaukee Bucks.
But he was fired in May after failing to push the Suns past the second round of the playoffs in 2022 and 2023. A month later, the Pistons picked Williams for their head coaching job, eliminating his need for a home in the desert.
The home was built in 1996, but had several updates during Williams' four years there. He bought the place in June 2019 for $2.375 million and immediately began renovation work.
"He redid the landscaping, put in a putting green and updated the air conditioning throughout the house to a new one," said listing agent Brian Kusmer." He also replaced all the grass with artificial turf in the backyard."
The work didn't stop there, though, and Kusmer explains that the kitchen underwent an exhaustive modern redesign that included self-opening and closing cabinets; high-end stainless steel appliances; and a butler's pantry.
Scottsdale's central location allows for easy access to some of the city's best stores and restaurants - a major benefit for the home's next owner.
"It's very close to Kierland Commons and Scottsdale Quarter," Kusmer said.
It's also one of the most expensive homes on the market in the 85254 zip code. There are only three listings in the area that are currently priced higher.
Williams, 51, played nine seasons in the NBA before moving into a coaching role. He spent five seasons as head coach of the New Orleans Pelicans before his four seasons with the Suns.
