House hack with siblings if possible.

@Brian Van Pelt Is that Docusign's lazy sibling?

Here in AZ I bought a house from three siblings after their dad died.

I think a better answer for this question would come from your parents or maybe an older sibling.

Came to the US with parents and siblings as a little kid and grew up with the work hard mentality instead of work smart.

My other siblings have done poorly, well, and very well in various ways. 

Here's where we get stuck: - I have a younger sister, and two half-siblings. - My wife and I have a daughter (who has special needs), and another little one on the way. - If either set of us (both my parents/ both the wife & I) were to pass somewhere along the way, where do the children/heirs fit into this at all?

They moved to a new house in a better township and brought my siblings with them and my growing family gets to move into my childhood home.  

if it's an inheritance, I'd assume your siblings also inherited or I'd give them $10k each. 

Homeless for 4 months with my mother & siblings, they wouldn't let me go to high school because we had no permanent address.
