Thanks again for responding.

If you have any suggestions please respond to this forum.

Sorry took me a moment to respond.  

Thanks again to all that responded. 

Would not respond to any calls/emails.

You might try an email saying that he is responsible for rent until you get another tenant,  the sooner he responds to confirm he is gone the sooner you can start focusing on finding another replacement tenant.   

But that does not mean you're required to respond to him even via writing.

@Wayne BrooksWhile I agree with you, I was responding to the  question of the agent commissions are non-negotiable. 

As you get more comfortable her you may find your self responding to and asking questions and sending private messages and networking.

Thank you to those who take the time to respond and help others expand their business.
