In the second quarter, Barton said, Zillow actually was able to sell homes for 5.8 percent more than it expected. In the third quarter, though, Zillow sold homes for 5 to 7 percent less than it forecast... Zillow was also buying homes at a higher price than the market average: $65,000 more in September. In Phoenix, the problem was particularly acute. Nine in 10 homes Zillow bought were put up for sale at a lower price than the company originally bought them, according to an October 2021 analysis by Insider. If each of those homes sold for Zillow’s asking price, the company would lose $6.3 million.
