I've been having litter issues with people dumping their trash and old furniture, etc and I keep getting notices and fines from the city for litter.  

With furniture and belongings, deficiencies can be difficult to see.I would explain to the new tenant that they are agreeing to use the original condition report from before they moved in, and get their signature to that effect.I would explain to the leaving tenant that the deposit stays with the new lease and they should work with the new tenant to get any desired refund from them rather than you.Otherwise everyone moves out and you start all over with deposits and condition reports while it is empty.

I haven't made any moves towards an attorney being how the tenant moved out on her own will, problem is is she hasn't turned in the keys for the old locks and still has a bunch of junk and furniture there.

The cost for furniture and pictures?  

Pretty soon car salesmen can be held liable for repossessed cars, furniture salesmen can be held liable when people stop paying on month 7, those poor cell phone salespeople........ 

He and his family weren't really using the cabin anyway, and it was mostly filled with old furniture and files and things they didn't want to store at their home in Illinois.

Basically, you'll be able to leverage your current assets (like furniture) and just switch marketing strategies.

The husband of the lady I hired to stage came along and dropped off furniture.  

I currently have problems with issues of smoking in the house (violated lease), noticed damage to the front door's lock, leaving old furniture in the back yard (killing a big spot of grass, because it was laying there for about a month or 2), getting notices from the HOA about neighbors complaining of possible illegal activities at the unit.  

If it's due to the size, then there's potentially a lot of furniture.
