My wife and I recently purchased 20 acres in the Columbia River gorge that we hope to develop into our homestead.
I've written about our entire process at length here:
Forest & Field Journal
The short version is this:
-We went from $20 in our bank account to $50,000 in three years making around $30,000/year.
-After exhausting all of the options on the market, we mailed letters to property owners.
-After getting a thumbs up from one of the property owners, we worked through the entire process, obtained financing, and purchased the land.
I imagine many folks out there are in a similar situation as we were. With the right amount of hard work and creativity, most anyone can make it happen, especially permies.
