>>1208023Land costs and building codes are one problem, how are you going to survive once you have your land and cabin? Have thought in depths about food preservation and rain barrels?
Look into jarring/canning tutorials and learn how to dehydrate and freeze dry your food so it will last even after you have harvested it. Collect water from rain, but make sure you purity it before you drink or cook it it.
If you are planning to move to Western WA, look up the YouTube channel Rain Country. It's a couple who lives off grid in the region you plan on going to. You can get a good idea of what challenges you can expect and what life is like in that sort of biome.
Good Luck, anon.
