1) Do not let 3k bike parked at campus (or anywhere else). Get beater bike... cheaper to replace when stolen.
2) DVC, cool, what campus?
3) You can look for apartments using online sites, google "find apartment in <xyz>" and that tells you an idea of how much is the rent.
4) You can also google "apartment ratings" and get some sites reviews of specific apartment complexes... great to check if there are too many horror stories about the place.
Besides that, there are lots of CA residents among these forums but most are sleeping now. Chime in later. Good luck.
