Is it ever a good time to buy a house in San Francisco? It's cheaper to buy a house in Sacramento instead and pay for the gas and/or transit fares required to commute.
That's a 90 minute commute by car, which is not very practical for most people. However, it is usually a better idea to buy a house across the Bay, where it is significantly cheaper, and commute the 15-30 minutes to work in SF or wherever every day.
