It doesn't have to be that extreme, you could just live in circumstances that you don't prefer that aren't on the road. I live in a dilapidated garage that is the cheapest thing around. I hate it, I have a playschool size "babys first refrigerator," no clothes dryer, far from anyone my age, etc... but I can save a few hundred a month that I would have otherwise been throwing away at some corporate landlord.

The idea was to do this until I made enough to afford a house, but COVID came and said "fuck your future and just about every one else's too. Also I'ma kill millions of you but somehow make housing prices increase anyway."
