I'm not 100% sure it is the right move to combine so much about your D and her R with her dad with the house situation convo. Even as I read it I got totally pulled into the concern about your D and if I were your ex, I might feel defensive about some of the things you're saying. Of course it is all true and totally fair for you to say that, but I wonder if it detracts from your primary goal right now, which is securing the house.
I might just stick 100% to the house stuff and then maybe offer a time for him to video chat with your D? Maybe the D part (right now, until you get the house sitch nailed down) is more like "Re D4, I know she'd love to talk to you!! Are you available at all this weekend? Let me know a good time and she'll be ready!" Or something just positive and bland. I think the other stuff about the importance of his R with her could backfire and make him defensive and not super interested in giving you what you want with the house, since it seems there is this weird reluctance to let it go.
You're doing so well and thank you for sharing your dating adventures! I love following along!
Aloha,
May
