Yeah, there's kind of a big flaw in this. I'm in California, too. It's a huge state, and there re giant swaths of it that don't have especially high cost of living, but the population centers like LA and San Francisco are very, very expensive. Taking the median isn't going to give you a realistic answer for most of us.
My last home was a 5 room house I rented for $2400 in the beginning and was $3600 a month by the time I was moving out. The place was a shit hole in a dangerous neighborhood.
