Been there. Principles cost money, it's not worth it.

Each jurisdiction has their own landlord tenant act, or not, you need to know.

You're already doing what you need to do, i.e., move.

Take the time to find out your rights in terms of last months rent, if they're holding it. I've learned, before I bought, never pay the last month. Let them use the deposit for that. It's pretty universal that you must receive that money back into your hand regardless of what the landlord claims.

In a very similar case, I used student legal aid, she was excellent, would still be my lawyer if she didn't go someplace corporate. I negotiated a quit claim on their violation for a quit claim on all increases and damages. (After all, they walked in to your perfect world.)
