A well written management contract should clearly spell out what is expected of both the PMC and the owner, to PROTECT both and avoid misunderstandings.

My goal is to determine if I can still use this LLC as a holding company while maintaining liability protection.

Occupations are not a protected class.

And the death-song has been the moment any accountability crops up for such a consumerism, the laser focus of protecting the consumer economy means blame Blame BLAME someone, something ANYTHING else for the falter because we "need" the consumerism...... 

A well written management contract should clearly spell out what is expected of both the PMC and the owner, to PROTECT both and avoid misunderstandings.

The laws and structures protecting tenants, landlords, property, and financing have changed, but the basic premise of buying and renting is more or less the same back to at least the Romans. 

First, I need to learn how to protect myself and my current tenant against some of the issues I've seen online where renters will stay past the date they're supposed to leave.

Don't make excuses or apologize or try to soften the blow to protect their feelings.

So, we are segregating off our rental endeavors to a single LLC to protect our other operations. 

I would also recommend Waivo or Safely for damage insurance protection.
