This is what credit is for, not for buying sprees. You can't get a cash advance of a few hundred bucks to get you through this?

FWIW, by New Jersey law they cannot refuse to renew your lease for one time late, as opposed to a pattern of lateness. They can however raise the rent up to the point at which a judge would call it "unconscionable". Search for and read the New Jersey pamphlet "truth in renting".

I'm also assuming that you're renting from some big management company, not a human who you can talk to and explain your predicament.
