She has dementia and is getting to the point where she may have to move to a memory care facility. She is very difficult. I can't travel to N. Y. due to compromised immune system. How can I move her, when I know she will resist any attempt by a stranger to move her?
Other than that, do you have any willing family in NY (which you could also compensate) to get things settled at your Aunt's end? The problem is if your Aunt puts up a fuss or calls the police and her PoA isn't present with paperwork in hand -- all the effort may be for naught and you'll both be back at square one. I hope you have success in finding a solution!
