Passive aggressive behavior at its best.I will ask them tonight what they are planning to do when the children come, we have talked about all the things i need to get done, and how tight of a schedule i am on at the moment so I see it as they are taking advantage of me because after everything they are still lollygaging around.STOP ASKING.   

As landlords we need to work together to reinforce good tenant behavior and punish bad behavior.  

The behavioral people call it 'Loss Aversion' and we often find ourselves paddling down that big river in Egypt because if we don't sell out of that bad investment we can delude ourselves (and hopefully our friends) into thinking we haven't lost money... but it's already gone and all that's left is the crying.

If your landlord knew about the dog and did nothing, this gives you permission to have it -as his behavior becomes a waiver of any type of rule against having a dog.Now, you could take a chance you'll get away with getting a second dog, in the event he notices the second dog and doesn't object.But, any problems with dishwashers and anything else, are completely separate.  

I hope you put your agreement in writing.Just for information: If you accept rent late, your behavior waives your right to any late fees or ability to enforce rent due on time.You can re-establish your deadline for rent, by giving notice in writing with 30 days notice.  

It's a miracle they didn't burn the place down, as it was apparent that they just dropped cigarettes regularly, that just burned themselves out on the carpet.So, did the co-signer change the risk/behavior of the tenant who wouldn't qualify without one?  

The issue I am exploring is not my feelings about alleged bad behavior but my legitimate responsibility.

Their behavior is indicative of deeper issues.  

I have wondered it there was something about my behavior.

Why else would would you attempt to justify such bad behavior?
