Properties being sold within just a few weeks of listing indicates a strong sellers market. Sellers are, in most cases, getting multiple offers due to limited inventory.

One region of the City experiencing a boost of mojo is the Central East section known as District 9 which includes the neighborhoods of Portero Hill, Dog Patch, Inner Mission and Mission Bay. Since 2011, the inventory of homes in this district has shrunk more than 42 percent with just 48 properties for sale in April 2013. At the same time, median prices in the area hit a 2-year high in April 2013.

The Inner Mission neighborhood has become a popular area for young tech professionals, due to its proximity to downtown, availability of mass transit, shuttles to Silicon Valley and an abundance of popular restaurants. The median price for a home here is $1,001,000, up 33 percent from the same time last year.
