Fair enough, but where? Back in the 80's when we bought our house in Sunnyvale, we could have bought one for much less either Livermore, Fremont/Milpitas, or South San Jose for much less but the commute would be high. Pretty consistently the outlying areas are about half the cost of the cities actually by the bay. Would love to hear more data points.
