answer:Probably not, if just for investment purposes. If you need to live there anyway for more than 5 years, maybe. According to the NYT, in every 5 year period except for the last, the stock market has outperformed the housing market. And San Francisco is still very high. When you include high taxes and earhquake insurance, it’s a very expensive market to own real estate. That being said, if you’re planning on living there for a while, there’s always a decent chance it will be a decent investment. But strictly financially speaking, I say no.
