Silicon Valley companies cause the San Francisco real estate market to go up.

Apple and Google use public bus stops to shuttle around their employees in San Francsico and elsewhere. It’s not just the fact that they use public bus stops, but most of all they are a sign of inflated real estate prices.

Realtors keep talking about an “overbid maddness” and cite an example where an elegant house in Bosworth sells for $600,000 above the asking price. In the Glen Park neighborhood a beautiful house even sold for mind-boggling $2.1 million.

Obviously, real estate follows the law of supply and demand. IT folks from Silicon Valley keep pushing prices up, up, up.
