My Grandpa is living on his own, he is 84 years old. My grandma is in a care facility and is in the very late stages of dementia. My grandpa visits my grandma at the home several times a day. He has become close friends with the owner of the care home. He is very well off financially, with approximately $750,000 in stocks, that he doesn't currently use for his daily expenses.
Within several months of my grandma moving in he gave a loan out to Ann's boyfriend for a car in the amount of $12,000, with the promise that he would use the money to restore the car, sell it, and share some of the profit with my grandpa. My grandpa was very open with his financial situation, and I believe that the care home owner is now taking advantage of him and his situation.
Recently he has let the owner borrow his personal vehicle for her own personal use, as well as probably transporting other clients around. She also recently proposed to my grandpa an idea that he purchase the plot of land that her personal manufactured home is located (in the amount of $80,000) "co-own" the care home, which would be moved from its current location to the plot of land that my grandpa would have paid for. Obviously, when I heard about this I was very worried, and told my grandpa that this was a very very bad idea.
I spoke with my grandpa about my concerns that I felt like he may be getting manipulated, but he is so stubborn, and he told me that "I'm not stupid" and that these we're "nice people." He has told me on numerous occasions that the owner of the facility is "not good with money" and "she keeps spending her money unwisely."
Hearing about all these side transactions and "plans" for possible future transactions made me and my wife worried, so we called the State to ask for their assistance and advice in the matter. They took down information and performed an investigation at the care home. They asked very specific questions about these transactions, which led my grandpa and the owner to know that we were the one's who had called the state. My grandpa called me, upset, stating that the owner told him that we were going to have her "shut down" because we called the state on her. He threatened to write me out of the will if we called the state again. I told him honestly, that this has nothing to do with the money, but about the care of my grandma, and his emotional well-being.
I don't know what to do from here. During the investigation by the state both my grandpa and the owner of the care facility lied about any transactions happening between them, and lied about her borrowing his personal vehicle. I just care about my grandma's care, and I want to know that they aren't using her as emotional leverage to try to get my grandpa to make poor decisions.
Should I just stay out of this and let my grandpa make his own (possibly poor) decisions? I feel like the owners are trying to turn him against me by making statements such as "your grandson called the state on me, and is trying to get me shut down."
