(Reuters) - Shares of Zillow Group Inc hit over a year's low on Monday after the online real estate firm said it would pause buying houses this year, as labor shortages and supply disruptions hamper timely sales of renovated properties. The company, through its Zillow Offers unit, buys homes from homeowners and performs light repairs on them, requiring the services of inspectors and contractors. It then lists the homes for sale on its platform. Zillow shares fell as much as 11.4% to $93.54 in early trading, their lowest since September 2020.
