Waggoner ranch which is 535k acres and also in Texas panhandle sold for $725M thus I am sure price is negotiable...
Big acreages like this are getting increasingly difficult to find and there are quite a few billionaires that value land eg John Malone, Ted Turner, Stan Kroenke so I am sure it will find a buyer...
LOL good luck finding a buyer who wants to sink 250M into that. Fancy video etc aint gonna cut it. No one is gonna stick 250M into illiquid real-estate in Texas with its associated holding costs etc.
