We're No. 1!

In terms of unaffordable one-bedroom apartments, that is.

That news -- which perhaps we should hesitate to describe as such, but there you go -- comes courtesy of the September report on U.S. rents from the rental website Zumper.

According to the site, the median rent for a San Francisco one-bedroom apartment is now $3,530, up 13.9 percent from a year ago, and almost 1 percent from last month. Those figures, Zumper says, are based on analyzing "rental data from over 1 million active listings across the United States."

Just think: What else could you get for that amount of money? Well, a one-bedroom apartment in New York City plus $370 back, for instance. According to Zumper, the Big Apple is No. 2 in terms of stomach-churning one-bedroom rents, with a median of $3,160.
