practicality

I have a job! Produce clerk at a local organic grocery store - I start sometime next week, although I'm not sure when, still waiting for their staff trainer to get back to me. So now the apartment hunt begins. I'm in kind of an iffy situation where on a regular monthly basis, I can afford a $700/month place, but right now I can't pay the initial first month's rent because I only have $400 right now, and I'm not sure what to do about this...suggestions, anyone? UBC is in a beautiful location, but this means that anything within half an hour of campus is expensive.
