@mattm25 Although I’m sure NCalRent was trying to be helpful, the link in that post is to San Diego State, not Santa Clara University. Different ends of California. 
SCU is a private school, and cost of attendance is the same for in state and out of state applicants.
As for financial aid packages, no one here can guess what kind of aid you’d be offered, so apply and see what happens. Best of luck to you!
