hey just seeing if anyone has any information on how to best break a lease.

situation in a nutshell is, my gf has a lease through may in a 3 br aptment that she signed on along w/2 other ppl. 1 of the other girls have already moved out, my gf is moving out as well and the 3rd roommate is a complete bitch and won't let them sublease or whatever.

wondering what happens if my gf and her other friend just stop paying the rent, obviously they'll prolly get evicted but does this affect their credit in anyway? or does this only affect their renters credit? any other penalties or any other ways to get out of this lease?

any help is appreciated, thnx.
