Nothing like a daily BART ride to scare you off of working in the Bay Area. Especially one deep enough into the East Bay (with a long enough bus ride to the station) to cut the rent in half.

An hour each way (20 minutes for first and last mile, 40 minute train ride) will save you maybe 30%.

but then you have to have a car! car payment + gas + car insurance + daily bart tickets... It can add up!

this equation is often true for non-family people I know: SFRent - EBRent <= OwningCar

for family people renting bigger spaces, the equation then might look like: SFRent - EBRent >= OwningCar
