The only non cost thing I can think of is that the ground below the frost line is at least above 32 degrees this will prevent any temp below that in winter and provide cooling in very hot areas. being in the NE USA the frost line is about 3 feet down.

For a style never using money you would have to be a hunter, fisher, gatherer, or a gatherer vegetarian. The American Indians were that but were nomads and moved to different hunter areas with the seasons and hunting gathering areas.

This style would be very hard in a set location for all locations are lacking in something, perhaps plant a white oak for flour and a walnut for protein will supplement but still hard to do.

The woods and land in its natural state is always lacking in something you will need you will have to terra form the land to the needs you have which will take many yrs.

For a no money lifestyle you will need to barter for the things you need, be it labor or item / food exchange.
