Let's say someone was bungee jumping off a balcony railing and the railing broke and they fell, injuring themselves.They could sue the property (ownership LLC) because the railing was "not secure".They could sue the manager (management LLC) for not ensuring the railing was secure.They probably will sue both and let the court sort it out.I don't see how 1% ownership of one LLC to another prevents any of the above from happening.

Additionally, they test to determine what sort of mold/s are present, so as to determine toxicity.  

Plus, after adding my wife to the account, QBO blocked me, and it took two months to sort out!

Based on what you wrote here, I think the lesson should have been to not chase a specific number of properties, rather chase a specific number of dollars.The lesson was to build some sort of active income within real estate through lending, which I'm currently doing, rather than chasing ownership of rental properties. 

You'll need some sort of active income, whether it's wholesale, fix and flip or lending.

Depending on the state he will likely not have any sort of case at this time.

Sort of like a fishing village, but great beaches, parks, etc. 

Feel free to inquire about their staff qualifications if it's a larger organization.2.

And what is the best way to sort and filter it before feeding it into these call center servcies?

Maybe they could do some sort of private reverse mortgage?
