Sounds like the last house I lived in, did you take pics of all the damage before moving in? It might be a good idea so that the landlord can't claim you guys did all the damage. This is something that happened to me before, landlord claimed we damaged the place & kept the security deposit & then sued us for another $2200, we ended up making a deal & getting it down to around $500 just to make the whole situation go away, but it was still shitty, we were still paying for damage that was there when we moved in.
That's an excellent idea. the landlord actually stopped by and walked into the house and had thenerve to say, "Everything is fine, yes?" as if he didn't enter the house through a broken door, walk up creaky ass stairs, through a hall with crumbling walls and chipping paint, and stand directly under a light fixture that was hanging on it'is side. We all resisted the urge to make sarcastic comments, so we just listed some of the problems instead. He said to make a list and give it to him. It's gonna be a long fucking list.
