The ninth largest U.S. school district, Hillsborough County (FL), in 2006 was "growing fast enough to fill five new schools" per year. To meet the demand, Hillsborough county used the services of 4 private real estate brokers, without using bids, in violation of its own regulations. Three of the four brokers have records of criminal, legal and financial problems. Some of those brokers simultaneously represented the sellers, or flipped the land themselves, resulting in land purchases often made substantially above appraisal values. Reporters from the St. Petersburg Times documented swampland purchases, and school sites surrounded by the homes of sexual predators.
