Urgent Help Needed for New Security Deposit

As some know, my fiance moved out in October and abandoned our lease. I have been paying the rent since then. As of yesterday my landlord is selling the Condo I rent and I need to be out by April 1st. I found a new place for March 1st,but cannot get the balance of the security since I don't know when my new job will pay me. Going to my mom's is not an option due to the dogs..If I wasn't in such dire straights I wouldn't ask. Embarrassed is an understatement.
