Rent? Fuck that. Your life is on the line and this is for all the marbles. You find a way to go rent free. Maybe do like the bums are doing all over the place, live in a van, etc. Nobody seems to care. Save that money and then get out.

By the way, the house I lived in at the end... Remember the house in Fight Club? That would have been an improvement.
