Zillow will flip houses on its own internet marketplace

Zillow will flip houses on its own internet marketplace

By choosing to buy and sell houses, Zillow is now officially an OpenDoor competitor. "We are genuinely excited, having invented this new category in 2014," OpenDoor chief Eric Wu told TechCrunch, "and it's invigorating to see a host of others in the industry recognize the importance of removing hassle and time from the transaction."

It doesn't sound like everybody's happy that Zillow has launched a new business model, though. As TechCrunch noted, its shares fell 7 percent after the revelation, probably because flipping houses has a whole other list of risks a simple real estate marketplace won't have to face. In fact, Zillow chief Spencer Rascoff has admitted that it's taking on debt to fund its new venture.
