Yeah, and then they went down in the dot-com crash, and then they went up again from 2005-2007, and then they went down again in 2009.
I moved to Mountain View in 2009. In late 2008 (as the crisis was hitting the stock market, but before landlords had realized it would affect them), a realtor was showing me around, and I asked about a swanky corporate apartment complex we drove by. "Oh, that's out of your price range - they charge $2000+/month." I ended up living there for $1400/month in 2009-2010, then they started jacking up the rent. When I left in 2013, they turned around and rented it for $2700/month.
