The Undertaker
Net Worth: $17 Million
Mark William Calaway is one of the most popular and successful wrestlers in the business to this day. Better known as The Undertaker, the 53-year-old still has an active career as a wrestler, despite being a free agent due to few people being willing to hire him. However, knowing that his career can’t last forever, Calaway has made a foray into the real estate industry. Like his wife, he has a passion for animals and as a result, the couple have started a fund dedicated to saving animals.
