Re: I want to move to San Francisco...but need a job.
Colma also contains all of the cemeteries for San Francisco. Due to space constraints, you will not normally find anyone actually buried in San Francisco. So Colma is considered having a very large population, but only about 10% of them are living now.

Don't forget San Bruno or the other areas closer to the airport, still make for an easy commute to downtown as well as San Mateo area too.
Rents can vary in the suburban areas as well, apts can go for over $2000 for a one bedroom out of SF as well, depends on the locale and what it offers as well as amenities.
You can also go north into the North Bay and commute as well.
But I would do things in reverse and focus on a job first and then look for living quarters afterwards. It will be easier to do that way.
Best of luck to you.
