OP here. I'm planning on doing postgrad study anyway, so I figure that's when I'll move out, plus I'll actually be able to afford it at that point (hopefully!).
On a less related note, I'm amazed at how many sensible replies there are: this is why I love text-only boards, as they seem to attract non-idiots.
Thanks y'all!
p.s. what exactly is a dry county?
