Take some road trips. For 3 years on our vacations we checked out Oregon, Washington, Idaho Panhandle, and Western Montana.
Deciding factors were:
1 hour distance to a good airport.
Hospital access.
Supplies...Food, Lumber, Welding, etc.
Free water...sky or creek
Recreation like fishing.
Weather. Drastic changes happen in a few miles. Roads that get little winter sun can be a nightmare. Bugs I lump with weather since they follow mucky soils.
Government intrusions. Some areas have little to no building permits.
Like minded people. Talk with the natives.
Make your list of wants and hit the road with open eyes.
When the market crashes (it will) get ready to pounce. Stuff doesn't sell well here like in the cities and prices can really plummet.
Good luck.
