Living in SF/Bay area with family of 4 (San Francisco)

Hi All,

I recently received a job offer to move from Sydney to SF. We're a family of 4 with a 1 year old and 4 years old kids. Been reading about crazy cost of living in SF and was wondering if with a household income of 200K we can live comfortable in the area? We'll have to pay kindergarten for the kids and rent an ok 2bed apartment in a nice suburb (in the city or around palo alto).

Thanks a lot for any help,
David
