So I don't deal with the public anymore but when I did I answered live when ever possible.. even if it was to just say hey I can't talk wanted to acknowledge you called and when can I call back.. folks like that

Do a walk-through of the property before the tenant moves in and ask them to sign off on photos acknowledging that all is in working order. 

Start by acknowledging that you have not been communicating in an effective way, that takes the pressure off her.  

I'm content to be able to see it, without outside acknowledgement.

If a borrower submits an application shortly before transfer, the new servicer must send an acknowledgment notice within 10 business days of the transfer date.

@GeorgeThank you for the acknowledgement.

And not just an acknowledgement that they received my email, actual research and answers, same day.

Tenant acknowledged in writing the landlord did not have control over the commercial space. 

The other three should have also acknowledged his role as "primary" by initialing the statement in the lease, and initialing that any issues would be handled through him. 

Your girlfriend will just need to sign documents acknowledging the HELOC is being taken out on a property she has 50% interest.
