How to deal with problematic renters

[Bobby Narinov]

I bet everyone has one of those renters that are constantly causing problems. The ones That are constantly complaining about anything:

• The rent is too high (but never move out)
• There is a toxic mold in my house.(Maybe if you clean the cinder/dirt in that completely dry corner you would have none.) I know your handy man told me that this is not mold but he is lying.
• The plumber stole my husbands $250.00 toolbox when I left him unsupervised because I could not wait 10 minutes for him to finish and leave. (The plumber have a brand new set as a present from me and have never seen any toolboxes there.).
• I can never send you the check on time but can I come to your house at 10PM tonight (5 days after it is due) so I don't get late fee charges.
• Your handyman did not completely fix the problem in the way we wanted him to fix it
• Would you pay $300 to our handyman because he did a great job. I know you authorized only $150 (which was twice over the prevailing amount) but I didn't want to bother you.
• There are too many cockroaches even after you gassed and spray them. (Maybe if you bother to clean your kitchen and stop leaving food all over the place they would not come back so fast). 

How do you deal with people that are never happy with what they have and are pain in the A$$ to deal with?
