So OOS undergrad costs along with Medical or Dental school costs are affordable? What is her plan B if a Professional school does not happen? If she likes cities, UW sounds like the better option. Santa Barbara is close but the UCSB campus is not located in town and SB is not a large city in comparison to Seattle.
Since she is coming from OOS, Santa Barbara has a small airport nearby but depending upon your location, may not have direct flights available.
