For some context, if you make $100,000 per year, a three bedroom in San Francisco would eat up 100% of your post-tax salary.

Over the last 4 years, prices have dramatically increased in San Francisco. From 2011 to 2015, the median price of an apartment in the city has increased 50% from $2,595 to $3,880.
