Can you tell us what kind of water rights, etc that you have to purchase? In Texas, water rights come with the land. Or, at least, they currently do and maybe those regulations have changed without me knowing it.
In Nevada, soil and mineral rights do not come with the land surface rights unless the previous owner had purchased them and include those in the sales contracts. Water rights are something that has to be purchased (except for domestic well for home use or pond under 20 acre feet) from the state and ongoing "beneficial use" has to be demonstrated or those water rights revert back to the state. So, if I purchase water rights for my entire 80 acres, I can have a well or pond or stream, etc... but I have to show that the water is being put to beneficial use or I lose the water rights and someone else, anyone really, could purchase water rights for my 80 acres IF they can make the argument that they can put the water right to use.
It's a sort of strange state in that regard... If I have a pond over 20 acre feet, I have to purchase water rights... it's only $250 though.
