I can understand a Financial Advisor/broker role here, but in the instant case, those funds are under control and safe. IT is the management of the Rentals that is causing all the grief here. I had something similar. Though the client was lucid, and getting buried in paper, she really did not want the help. Some folks, no matter what, do NOT want to admit that they may be messed up... I offered to come by the house and help sort stuff, or even one of my lower cost staff members. No.
There are appropriate ways to bring in support. But you can lead a horse to water...
