If you know something about SF, I'm curious - on a typical assessment of that sort of house, how much of that is attributed to land, and how much to the house (2br 1300 sq ft, the sort that would sell for <$180K in a normal city in a wealthy coastal state)
Also, when people talk about the price of living in Manhattan, the obvious response is - so don't live in Manhattan. Can't you work in the Bay Area without living in SF proper?
