The SF chart didn’t display right, you can add it with the “Add image” link near the bottom of the comment page. Or email it to me at rich at piggington and I will put it up.
Anyway it’s not too surprising about SF; incomes have gone absolutely nuts there because of the tech boom. You have software developers (individual contributors, not managers) making over 500k. So incomes have gone up way in excess of inflation. How sustainable it all is is another question, but it makes sense that SF home prices have risen much faster than inflation. (If you could find it, it would be interesting to chart SF prices vs. incomes).
