Berkeley Housing Advance Payment

<p>Hi all. I was just wondering if anybody has ever gotten an exemption for the $300 advance payment? I called today and got a reduction, it's now $150. Still, this is more than my family can spare at the moment--we're super low income, with 0 EFC and all that. So I'm planning to call again on Tuesday, but I just want to know beforehand if it was possible to reduce the $150 even lower. Thank you in advance! :)</p>
