There are some people who buy a house and live in it for years, if not for the rest of their lives. Then there's Ellen DeGeneres and her wife Portia de Rossi. They are what you'd call 'serial house flippers.' Since 2003, Ellen and Portia have bought and sold more than 20 properties. In 2019 alone the couple sold three properties, of which the least expensive one was nearly $7 million! It all started back in 2003 when DeGeneres bought a house in the Hollywood Hills for $6 million. Basically, DeGeneres buys and sells luxury California properties. Sometimes she moves several times a year. While she does make quite a nice profit from this practice, moving that often sounds exhausting. But, I suppose, when you've got a net worth of $400 million you can hire people to pack your home, move it, and unpack it, while you relax at a spa. Or, if you're Ellen, one of your other houses. She's sold her flipped homes to a number of celebrities like Ryan Seacrest, Napster's Sean Parker, and former Google CEO Eric Schmidt. She's bought properties that formerly belonged to Brad Pitt and Adam Levine – both of whom are also pretty much serial house flippers. But, don't call Ellen a flipper. In an interview on the Today Show, she said that she and Portia move so often because they enjoy it.

"We buy a house and we love it, and we stay in it. Then we get a little bored because we like a different style or different aesthetic — and I love furniture and decorating — so if I find something else, and we make money, why not move to another house?"

She documented her journey of buying and selling houses in her 2015 book, Home.

In the Today Show interview, DeGeneres also explained that growing up they didn't have a lot of money.

"We lived in apartments. We would look at houses every Sunday, we would go to open houses, but we could never afford a house. As a kid, I thought — 'That's going to be my house.' Now, I just buy as many houses as I can."
