How does one purchase so much Land?

In the early 1960's, Walt and a team of Imagineers, including his brother Roy and General Joe Potter embarked on a super-secret endeavor, known simply as "Project X", later known as "Project Florida", to scour the nation in search for a new location for a second theme park. First and foremost, they were looking for a lots of land. Second they wanted it to be near a major city, with good weather and great highways and infrastructure. Reportedly, when Walt's plane crossed over the intersection of I-4 and Route 192 in Florida, he knew he had found his location.

But how does Walt Disney go and buy up thousands of acres of land without the landowners holding out for exorbitant prices? Walt Disney set up dozens of "dummy" corporations, with names like "M.T. Lott", the "Latin-American Development and Managers Corporation" and the "Reedy Creek Ranch Corporation" to purchase seemingly worthless parcels of land ranging from swampland to cattle pastures. By May of 1965, there had been major land purchases recorded in Osceola and Orange Counties, just southwest of Orlando, although no one realized or suspected at first that Disney had anything to do with it. One of the earliest purchases included 8,500 acres owned by Florida state senator Irlo Bronson.
