So 3 siblings on properties, 3 cash out. 

This option does not involve my siblings, at least I’m not sure how it could (they probably would not be able to assist in deals/management etc.).Are there better options to build generational wealth with this scenario?

All in all 100k spent ( 70 k to repair apartment, housing the tenants for several months in a hotel, ordered to pay them 10k, and now attorney is advising us to pay them 17k to not sue (extortion) I’m newly involved (owners are all siblings/cousins-12 in all) Sorry for the long post, but ??? 

In De I believe the first in line is children, then parents, then siblings, and that's as far as I know.  

but it has a much lower risk sibling - seller finance.

I have been 1/4 owner of a property and am now buying out the other three owners, all siblings.

My dad used to handle estates for relatives who can't speak English and had the same problem.In fact, her two siblings would have her make calls and write letters as she's the only one authorized to act, through the legal document, though her siblings are also heirs.

No spouse, kids, parents, or siblings?

Furthermore, the 20 year olds in your circle or SOI have aunts, uncles, cousins, siblings, parents, in-laws, neighbors, coworkers, and friends who will need an agent at some point.

Buy out the other two siblings.
