This is the response I have received from the property management company:
I apologize we made a mistake. If it helps and makes you feel better you can personally hand your checks to me (property manager).
So this was sent to me in COMIC SANS.
No I do not accept this. What exactly was the mistake you made? Why are my checks being cashed at a check cashing market? So all of a sudden the check you can't cash doesn't matter? Why would I feel any safer handing it to you, if the first check I handed you was cashed at a check cashing market?
What would you all do? I am going to write up an email response soon.
It's sooo suspicious and I kinda want to expose them.
