Like others said, check the local rules and regulations when it comes to everything. Resource rights, building codes and what you may and may not do on your land.
I also know the locations of all police and military stations in the area because out here where I live they control everything. Make sure you check the local crime rates in the area you move to and also some health statistics. You don’t want to move and later realize there is a coal burning plant just a few miles away that constantly messes up the air quality and increases your risk of lung cancer.
It is pretty much impossible to live in a complete natural disaster safe zone so be aware of what can hit you.
