crooked, crooked landlords

We have 6 days until we have to officially turn over our keys to the ghetto abode, but I am hoping to make it sooner. The past few weeks Ken and Lisa have shared their saga of the "Security Deposit" and given me even more insight into recognizing what conniving people our former landlords are. Monday I went over to try to do some cleaning and get more stuff out of the place. I knew Mr. Landlord had been in to install additional smoke detectors (he asked Matt about it), but the first thing I noticed once I walked in was the lighted ceiling fan attached to the living room ceiling, a new addition to a room that previously had no lighting. So I cleaned the bathroom floor, scrubbing around the base and washed the baseboards. This morning (after all the rain), we got a call from Mrs. Landlord (who I'd rather give a much less flattering name) saying that because of the rain, Mr Landlord might be in the property to check on flooding in the basement, because other places were having problems. Matt dropped me off at work and headed over to do some cleaning and get the last few things out. When he got there every door in our apartment was unlocked and open. The screen door on the side of our house was not even latched and no one was around; no minivan, no truck, no Mr. or Mrs. Landlord! (Some of the items still in the house included Matt's computer) Matt called me because he was so very, very mad that he knew he would say something inappropriate if he called, so I did it. I called and ended up talking with their daughter who said she would pass on the message and have them call Matt; no one ever did.
THEN I got a call from Lisa. After giving Mr./Mrs. Landlord a significant hard time about the 30 days (that ended yesterday), she got her security deposit back minus the carpet-cleaning fee. That, I was happy about. Then I got an additional tidbit of information about Mrs. Landlord, she conveyed to Lisa that she wasn't worried about having to do work on the apartment after they moved out, but said she thought she would have to do "a lot of work" on our place. What the hell?! Nothing like getting slammed by a lying, cheating, stealing slumlord.
So needless to say, I was tempted to leave the place in as horrible a condition as I could, so she wouldn't be disappointed, but I think I am going to clean it up, take a crapload of pictures and sue the holy hell out of them if they try to keep any of my money. But unlike Ken and Lisa, I am not going to let them know about my knowledge (or possession) of the Tenant Landlord Act. I'll let them dig their own graves. They've done a pretty good job of screwing themselves my moving crap into their other places. They're not keeping my honest money.
Now to sell the downstairs couch...
