Here's my advice for what it's worth regarding searching for land in the Okanogan:
"Dirt cheap dirt " was THE site I lived on 24/7 for about a year.
But we found our land by driving around back roads and calling a number scrawled onto a metal sign the said for sale and looked to be about 30 years old.
DO come in winter so you know what access roads are plowed by county and which ones YOU will need to plow.
Come back at least in high summer so you know just how dry the land will get.
Get to know as many locals as possible. Go to as many meetings as possible.
Tell everyone you meet that you are looking for land. Having a clear idea of what you want to use it for will help.
Talk to Peter James.
Understand that being really remote 20-30 miles from town equals cheaper land but higher fuel bills and vehicle wear. Unless you only want solitude.
North facing: wetter, more trees, less sun, shorter growing season, cold longer but cooler longer too. May use more fuel to heat.
South facing: drier, fewer trees more grass or bare soil, solar aspect better, warmer sooner, hotter longer, longer growing season, may use less fuel to heat but require more cooling strategies.
It all depends upon what you want.
Ask locals about the various "neighborhoods" if they will tell you.
Remember down in the valley. All soils have been exposed to decades of heavy metal sprays for the 100+ year old fruit tree industry. That stuff is still in the soil. And they still do loads of spraying of orchards in spring mostly.
But the valley does have irrigation district access ( you must pay $)
Get a soil test or hire Mariah for a quick assessment of your potential land purchase.
Same with well drilling get a driller to witch it to understand the water potential.
Save a bunch of your cash for initial infrastructure. If at all possible. Getting income producing work here is difficult. And not having a cash cushion will certainly slow down your progress of even permaculture broad acre "development" or healing.
There are good people here. They are from many different and varied "tribes". Spend time contributing to the community by volunteering and you will build good friendships.
