Depending on what the SFA situation is in the area, you might be able to apply for a surplus quarter through DHE. You pay the same rent, however if DHE needs the quarter back for a family, you'll need to vacate. I've known a couple of people who've occupied surplus quarters and none of them have ever had to vacate early.
You'll definately need the support of your CoC, i.e. a short letter from your Boss to DHE supporting your application.
