Ellen DeGeneres, Jeremy Renner, Diane Keaton and More Celebrity House Flippers

The talk show host isn’t shy about her side gig, which she told PEOPLE in 2015 is, “really a genuine passion of mine, not just a business venture.” DeGeneres has purchased more than a dozen houses (and sold nearly as many) in the past 20+ years, and doesn’t plan on slowing down. “We are having a hard time staying put,” she said in the feature of her and wife Portia de Rossi’s itch to design. “I keep trying to find a better home. But I’m happy. This is what I love to do.”

Diane Keaton specializes in historic renovations, with one of her flips that she reportedly picked up for around $8.1 million selling to Glee’s Ryan Murphy for $10 million, according to Forbes.

Nate Berkus and husband Jeremiah Brent are no strangers to design.

Robert Van Winkle AKA Vanilla Ice told the Wall Street Journal that he likes to inject “flavor” into the homes he builds and renovates for his lucrative side gig.
