Tactics tried
Thanks for your attention. This has been going on since April '05. When he began working, we required he pay $500/month room and board. He offerred $100, which he has been paying. He has been informed numerous times that $100 was not acceptable, that he must provide pay stubs if he wants to negotiate a different amount, and that we consider the $400 difference debt he is accruing to us. This has been in writing (email and posted on his door).
About Dec. 5, I instructed him to leave by Jan. 1 2006, and that a three-day notice will be coming.
There has never been a rental agreement signed.
