Richard, your post in the "Full Times LLs" thread got my attention. I hear you - I have an entitled millennial myself. I think that you're on the right track with setting up trusts that will give her some assistance, without her getting the entire value of what's left when you are gone. For now.
But I'd like to suggest that it's time to stop talking about the business and about her attitude. She's your daughter, and I'd urge you to keep reaching out to her to have a relationship. Talk about family, talk about books, movies, beaches - whatever interests her. Reminisce about the times when she was little. Be open to advising her within your areas of expertise - cars, taxes, whatever you're good at that doesn't necessarily involve rentals.
I've been learning to do that myself - and after almost 2 years of incivility on her part, things are slowly changing. I told her that I would stop harping on certain topics, and that I will be here when she needs me. I advise her how to navigate the complexities of taxes and insurance when she needs that. Her dad helps with car and minor home repair issues questions. After a lot of coldness and emotional distance, she is beginning to thaw.
We hope and pray that the change that we see will continue to grow, and that some day we ourselves can change our wills so that she is an equal partner with her sibling in decision-making when we're gone (currently the older sibling and one of our brothers would be trustees).
I don't know your exact situation, but I just wanted to urge you to, if you don't already, find common ground and build or rebuild the relationship. You can but try - and you just may see her do a 180. Either way, you can be satisfied that you took the high road.
All the best.
