Biotech research currently. High end microscopy. I would probably have to be within commuting distance of Phoenix unfortunately. But you are right, I have made it as a waitress for many years...There are lots of things I am capable of. If I banked my equity I could likely buy something outright and eliminate a large part of my expenses. But I have ailing family members to care for for a few more years first. I have looked into it longingly for decades.
Phoenix or the surrounding areas are a horrible idea! There is NO water, and it's going to get worse. (Look at Lake Mead, which is where most of the water comes from)
Another major factor to consider... WHEN, not if, the shtf, there are only a handful of roads out of the valley. It doesn't take more than one accident / wreck to turn the highway into a parking lot. Not a good place to be stuck during a bad situation.
We had a very nice home in Peoria. (a suburb of Phoenix) I sold it for about 2/3 market value just to get out. And yes, it was worth it!
I suggest Apache County if you are looking to avoid regulations & such.
The building dept is by far the best / easiest I've ever delt with.
They are quick to answer questions & offer help / advice, without getting into your business.
For the most part, the few people that live here are decent. Most are... "not loaded with cash." But self sufficient, so money isn't an issue.
There are a few issues that some don't like. (I personally love it).
The first is the lack of law enforcement. (I'm a retired peace officer, so noticed that immediately.)
This is a huge county without a large budget. The few deputies available are many, many miles away and likely very busy. We are pretty much on our own. Don't let that scare you too much. People commit crimes... and there aren't many people here.
There are few, if any jobs here so... you work for yourself or don't work.
Town... if that even qualifies as a town, is quite the trek for groceries & other necessities. Plan on wasting most of the day.
Many places, like ours, don't even get U.S. Mail delivered. It's either by a box, many miles away on the highway or the Post Office. UPS & FedEx will deliver "if" you have an address.
Get over those "flaws" and it's as close to perfection as I've found.
