Yeah, right. My barely mobile 90-year-old parents, one of whom has Parkinson's, are just going to pack up and go. They know perfectly well that they have a captive audience.
Thankfully, my mother died before the acquisition, and my father died last week, only a few months after the acquisition, so I don't have to deal with this any more. But caveat emptor: if you ever go into a retirement home, think about what will happen if they change ownership. Even if it looks great, or even acceptable, now, there is no guarantee that it will still be great, or even acceptable, tomorrow, unless you somehow manage to negotiate such a guarantee. I have no idea what a contract provision like that would even look like. But I am going to be facing this problem myself some day, so I'd love to hear ideas.
