Big investors, mostly backed by Wall Street, currently own about 13,000 houses in metro Phoenix, according to data provider The Information Market. Most of the houses are rentals, and few are for sale.
Market watchers are carefully tracking what these big owners — among them Blackstone Group, Empire Residential, American Residential, American Homes 4 Rent and Colony Residential — are doing with their Valley houses. Too many former rental homes for sale in an area could drive down prices.
