scu is even more expensive....if you can afford scu why not choose stanford?
scu is targeted for posh christian family kids ....
if i were you (assuming you have $30k to spare /year ) i would  go stanford..

living cost?..yes its  $1k/month (cheapest) single bedroom apt, you can find cheaper one..but i guess you dont want to live with low income hispanic and black community...where even a postman doesnt want to come in fear of getting robbed or watever......if you rent a room (in a family house- mostly vietnamese and indians) its $400-$500/month,,,and you have to eat outside...

solution?....find some nepali students and share apartments...
part time work?...dont expect it as a texas fortworth....

good luck..
