Santa Barbara is a terrible place to consider for buying/building a house. Sky high property taxes and inflated property values are begging the local economy to dry out due to rental prices (The Bay is cheaper if you compare similar apartments with similar interior/exterior). The city can't expand because of geology, and it refuses to build up to preserve the "historical view of the Riviera". Sure it's a pretty city, but it won't mean much if it's dead.
Buying is way cheaper in Santa Barbara than the bay area like half to two-thirds depending on where you compare to. The only thing even close to Santa Barbara prices for sale when I checked a year ago were "unique" properties in East Palo Alto. Rents are pretty insane here though. It's a total flip from when I moved here (I was paying $50/month more in rent than a friend who got a job in the Indianapolis. I lived walking distance from downtown).
There are plenty of 2br apartments for ~$2.5k on the east side of the bay (San Leandro, Richmond, etc.), and you will have better job opportunities as well.
