Bay area is obviously way expensive. I would give anything to live in San Francisco. One day I hope. As far as flying out of Oakland, I know of a pilot that lives in the valley and drives in to Oakland for his trips (lives in Turlock). If you are going to commute from the valley to Oakland, I would recommend living in another base. The valley is certainly not as expensive as Oakland, but the costs are still up there because its California. The valley is nothing like the bay area. Very hot and dusty in the summer and very cold and foggy during the winter. I lived there a while and every chance I got I went to San Fran. Its probably better to live in a cheaper base, put away some money, and move to the Oakland base after you have already saved. If not, renting in the area is possible, but you would be dumping a lot of hard earned money into property you will never own. Just my opinion....its almost nice enough to do the renting thing though. Quality of life is amazing there and almost worth the money.
