If you’re buying land in AZ without a reliable well or utility hookup, you’re buying a nightmare.

There is plenty of land with reliable water there.

Rainwater for irrigation, maybe. But the reality is, most of AZ gets monsoons a couple months a year, and then essentially zero precipitation. So unless you have land favorable for setting up a dam or something, you’re going to have a hard time living off that kind of setup.

Flagstaff and Phoenix/far south being a bit different.
