Great place for a startup: rents up 10.3 percent in San FranciscoThe best advice you got from successful entrepreneur Patricia Handschiegel? "Don't spend." Good luck with that if you're living in San Francisco. Bootstrapping entrepreneurs and everyone else have to live somewhere and if its in the foggy city its getting yet more expensive for many. San Francisco rents increased 10.3 percent in 2007. According to Curbed, that's the highest rate increase in the country. Rents increased only 7.7 percent in 2006 and a mere 3.8 percent in 2005. Over 60 percent of San Franciscans rent, and it may be time to look into buying for those with savings — on the flip side, home prices fell. Remember the good old days before Google bought YouTube for $1.6 billion? (Photo by greencandy8888)
