I guess you need $160,000 a year to think things are affordable to live in San Francisco!
You do need money to afford to live there. A brother-in-law living in SF makes about $40,000 a year in a non-professional job but he’s just getting by. He owns his home, bought it in the early 1980s when they were only about $150K, but took out equity loans against it which is why he’s just getting by. Refuses to cash out and live cheaper elsewhere. Living space is the biggest expense in SF, and prices out a lot of folks who can only afford to live in the suburbs where prices are lower the further east you go. My daughter worked as a manager in the medical tech/genetics field, which is very big in SF and the area. Also a growing field, dozens of new buildings popping up.
