30 or 40k is not enough to live on comfortably in most of the us, much less the larger west cost cities. Is the goal that low? Seems way to low.
My home owner's taxes are more than half that. Probably the idea is live in a place that's less expensive (which is not stupid), but I also want to live in a place with interesting things and people and good climate and jobs and schools, leading to a 'nicer' city I think.
