Paying for help is not for everybody especially if they enjoy the work and have exceptional behavioral regulation.  

I love Queens and I love New York but some things here are so backwards.It is WILD to look the other way from negative behavior and punish those who defend themselves and their possessions.

If you are going to post it before doing the work, make sure you add the date when it would be available to move.6) I would make sure they understand the policies and rules in the lease agreement and expectations regarding rent, maintenance, and behavior.

Indeed, logic doesn't always dictate behavior, especially when there's an opportunity for the banks to make a lot of money.

Know how I'm going to reward their behavior? 

Most tenants would correct their behavior in fear of losing their voucher.

Since then, I have observed human behavior in just about all its forms.

I include pass on of any HOA fines due to their behavior.
