Zillow reached an agreement to sell about 2,000 properties from the home-flipping business that it's winding down. New York-based investment firm Pretium Partners will purchase the homes, according to a person with knowledge of the matter. Pretium owns more than 70,000 rental houses in the country, making it the second-largest single-family landlord behind Invitation Homes. Zillow, based in Seattle, announced last week that it's pulling the plug on its tech-powered flipping operation after an ambitious effort to transform the company collapsed when its vaunted pricing algorithms was unequal to the task. The company plans to take writedowns of as much as $569 million and reduce its workforce by 25 percent as it winds down the business in coming months. BLOOMBERG NEWS
