If you want to live in a city, it's not the cost of the house that kills you: it's the dirt.
In Seattle, where I live, my property tax statement tells me that my (large, nice) house is worth roughly half as much as the land it sits on.
Given that these domes don't float, you still need a place to put 'em. If your goal is to opt out of the cost of housing - an evil which this blog post expounds upon at length - your first order of business isn't so much "what to live in" but "where is it going to be".
