Ah, finally a subject I would LOVE to talk about! Landlords not returning deposits duely owed!
When my son rented his second apt, my sister who is a professional cleaner (and the best in Musc.) cleaned his apt. 6 months into the lease and cleaned when he moved out. We took pictures and video tape of the apt before the keys were handed in. They called him later and said he would not get his deposit back. I called them back and they insisted that he would not get his deposit back. I then informed them that my son had no money to fight them in court, but I did. I also informed them of the pictures and video I had. He got his deposit promptly returned to him. (P.S. They used some bullcrap that the apt had to be professionally cleaned. I informed them that it was.)
When he moved out of his 3rd apt, he got his full deposit back promptly. No problems there, but I did discover to use a newspaper in the pics or videos to verify the date.
So take pics of your place before you move in and after, and use a newspaper to verify the date. And ALWAYS read the WHOLE lease before you sign it. Ask the landlord for a checklist of stuff to clean when you move out.
I had a couple of landlords from hell when I was younger and I didn't want my kids brow beat by trash like that. A landlord should appreciate a clean place when a tennant moves out and not try to screw people out of their deposits.
