It might be efficient to look-up people you already have phone numbers to just as a control.

My mother is trying to sell her parents homestead after her father passed away earlier this year.

However, it is my understanding that funneling funds from one child LLC to another as you suggest (even under the umbrella of a parent holding company) would still be seen as co-mingling. 

This means that as long as the loan was obtained on or after June 1, 2016 and the LLC you transfer it to is controlled by you, the borrower, then the lender must allow the transfer to occur without triggering the due on sale clause."
