I'm not sure about affordability, but as everyone has mentioned, the west coast states are INSANELY competitive. I'm native to California and I have decent enough stats, but I haven't gotten into any schools in California, Oregon, or Washington. Had I realized how unlikely it was to get in, I might have saved the money on application fees, LOL. If you're looking into the western states in general, there are some outstanding programs in Montana, Idaho, Colorado, Nevada, Arizona, and Wyoming! My advice is not to give up on the west coast, but to spread out your applications to a wide array of schools!
