I currently live in San Francisco and yes, rent is similar to that of Brooklyn -- around $600 - $1200 a month for a single person... Although I disagree, you don't need a car. The city is small and very bike friendly, and there is a great bus system. Having a car is more trouble as there is no parking anywhere. While rent is expensive, other costs of living are not. You don't need to heat your apartment, and eating well and going out are not inflated like New York. Comparatively though, in my opinion, SF doesnt have a very exciting art scene, most young people you meet are involved in the tech world. There aren't that many alternative showing opportunities for emerging artists. SFAI doesn't have an incredible reputation anymore (it was hot in the 70s and 80s) and to me doesn't seem worth the money you will be taking out in loans and cost of living in San Francisco.
