According to the first link, $1300-1600.
Because of all the foreclosures, many people need places to rent. That generates a lot of competition for the available rentals. Supply and demand dictate that prices will go up. The medians may already be out of date.
Good luck! Many are finding they do not have the luxury of being picky. Finding anything acceptable and available can be a major accomplishment.
great question, however I have seen condos / apartments range from 1,300 - 2000. depending on condition, age, upgrades, etc. (seems that properties with walking distance to BART are closer to $1600-2000.
