Conor McGregor – $23 Million, Las Vegas

Conor McGregor is a popular UFC fighter who has branched out into boxing as well. McGregor has built an impressive net worth but instead of purchasing his own home (as rich celebs usually do) in Las Vegas, he opted to just rent a posh estate. The place was like his very own palace and he named it the Mac Mansion.

The mansion boasts a huge living area, a game room, and a massive resort-like pool. In 2018, McGregor released his own whiskey brand called Proper No. Twelve Irish Whiskey. He’s retired in 2019, with a record of 21 wins and 4 defeats in the MMA.
