In San Francisco it can easily cost $10K to get situated into a new apartment. The average rent is $2300, so $6900 and broker fees just to move in. Plus, she needs all new stuff.
As a side note, how big are those appartments in San Francisco? Here in Paris for that kind of money each month you get 60 square meters and no single person can afford those. Most live in a third or a half of this surface.
