Before you spend a nickel do some research to see if any wells have been drilled in the area and how deep's the water. If you need to go down 300-400+' for water, the price of that land will be chump change compared to the price of drilling a well with no guarantee you won't be buying a duster. Without water the land's not worth much.?ÿ
I am personally familiar with this area and would be shocked if the original surveyor set ANY monuments. There could be some, but I would charge more than the property is worth just to perform a search. I probably would decline any reasonable fee to set any corners. There is a reason that only rabbits live there...
Methinks that in Arizona a 300'-400' deep well is a shallow one. Best be sure that it is on your lot.
Pretty much the same as Oklahoma - lots with no well, no survey, can be had practically for the asking. With well, with electricity, with access road, with survey - now you've got something.?ÿ
