We had a project which has hit several bumps in the road due to contractor reliability or rather lack thereof.

It sounds like you’ve got a solid plan in place for protecting your investments and managing your rental properties efficiently.

I am planning to do some flipping projects in the South Bay.

I'm not an attorney, but have faced similar issues to what you are discussing.Seems like anything that includes you personally, not as a manager, officer, etc, opens you up for liability. 

For any of you medium to high volume flippers, I'm curious as to how you compensate your Project Managers.

Which is really the crux of my argument here to is people jump through hoops "thinking" they are saving the world but I still cannot get anyone with 2+ million members here on BP tell me if they use a property manager and have reviewed and gone through their insurance policy on the property tell me what could they possibly be sued for that an LLC would protect them from?

Currently managing 2 short term rentals in Los Angeles.

I'm thrilled to begin my first fix-and-flip project in Lakewood, Cleveland. 

Here is the sheet I use to manage all my rehabs. https://drive.google.com/open?
