I will soon be navigating similar waters.
The problem is my parents own homes in Mexico. I have dual citizenship so that piece is not a factor in my dilemma. They also have homes in CA...where they have lived close to ¾ of their lives. I will not live in Mexico, period. I will not live in CA, either; even for a couple weeks at a time. Their primary home now (our vacation home) is in Mazatlan (my eldest lives in their 2nd primary home in CA). The Mazatlan home is a three-story mansion near the beach...soon they will not be able to climb up/down the stairs. If they want to spend the rest of their years in MX, it will be on their own. That is a SIGNIFICANT risk and one they would need to evaluate but at their age (early 70's today) may be biased toward MX. I will/would not live there.
My sister in CA is a selfish, self-serving, woke, Liberal c<nt (an RN with an MBA). My sister in Raleigh is an in-n-out out of rehab drug & alcohol addict loser. So that leaves me.
I recommended they speak with an attorney who will advise them on plans when they are not medically and/or legally cleared to make any decisions or in their absence. I believe they've set that all up but I'm not sure. In MX, it all comes to me by default as my sisters are not entitled to any assets because they are non-MX citizens.
My concern is where they decide to spend their last adventure. I'm the only one that would/will commit to care for them but in order to do that, they'd have to move here, to Knox, TN. My dad would do it but not sure about mom. I have a 5k+ sqft. home and a guest house. They would not be an inconvenience to us. I'd readily hire a 24/7 care taker. I'm not confident they would agree to move here.
There is so much uncertainty. The future is opaque because they don't like to share personal details about their finances/business/persona life.
