Instead of denying them, can we refer them directly over to the owner for them to sign a lease with the owner who is willing to effectively manage the contract, payment and relationship BUT would still want to retain us (albeit for a lower fee) to deliver ONLY guest and property care activities (guest communications, organizing cleaning, lawn and pool care etc). 

Make sure you have all your communication.

I would suggest that you should have your property manager manage all communications.

Get authorization to use them to reestablish communication if she is ever incapacitated, incarcerated, or deceased.

I know they have both received their respective letters because the upper tenant responded promptly with the contact info I requested.Upper unit tenant has been awesome and super easy to communicate with.

I can’t speak for that software, but the software we use, AppFolio, will handle marketing, maintenance, invoicing, and all tenant or owner communication from the same place. 

Perhaps a poor way to communicate it to those who arent aware of LSU but it's the best I way I can simply explain it.  

If the broker knows, and you know, that the client has communicated that they would not entertain any offers below a certain dollar amount... what's the harm in a formal rejection letter? 

It was kind of an emotional purchase but it's been working out so far!)

Note, this will be the last communication with you.
