How much per month will a 1 bedroom apartment in Financial District South, San Francisco cost?

Well Christina, because this is favorite spot for high rollers and brokers, the Financial District South is one of the most expensive places to live in San Francisco. A 1-bedroom will run you between $2900 and $5900. (Just to put that in perspective that is roughly between $35 K and $70 K/year.) That is the mortgage for a lot of houses in the Bay Area.
