Many people who are concerned with Hubbert's Mesa want to "live off the land". It is a wonderful dream to find a place that will provide you with all your needs. By all means, if you have the ability to do so, finding a good place to crash is well worth pursuing. (If you're looking in western Pennsylvania, I can even help you.)
However, first and foremost, you need to realize that perfection is not possible. REAL real estate will always have something missing. Some deficiencies can be corrected, which is all the more reason to start sooner rather than later. Other problems are not feasible to change, you will have to decide whether it is something you can live with. Consider your needs in their time order both when deciding where is an appropriate place to live and what projects to start with. Also consider the kind of community you will be living in, including the neighbors' attitude and the local zoning codes.
What if you can't afford to move? You can still do your best to live off the land you live on, like William Hunter Duncan. You may have more to be more creative in finding solutions, but the most important advantage is that you can start doing things now, like planting a garden. Invest in your skills today and "live on the land". It may even help you save enough pennies that finding the perfect place becomes feasible.
The Long Ascent begins where you are right now.
