So the LLC protection from liability varies from jurisdiction to jurisdiction. I have personally seen judges go right through corporations right through LLCs is if they didn't exist. Even when there was also the protection of the workers compensation act. Meaning an employee suing his employers LLC.
But anyway I keep telling everyone to buy more insurance. An umbrella of for a million dollars cost $300. That's pretty good protection.
I can also personally attest that personal injury lawyers don't want to own buildings. They don't want to pierce corporate veils and go through and find landlords personal assets. They don't want to do all that crap.
They much prefer insurance adjusters writing checks.
One last point that nobody's mentions. And most jurisdictions and certainly mine. If you self-manage you will not get the protection from an LLC. You are the manager. You will always be personally liable for your own activities.
23 LLCs will not protect you from your own actions with respect to the building. If you want the LLC protection, you're going to have to hire outside management. And don't ever visit the property because that's an inspection where you should have figured out what was wrong and fixed it before the tenant or whoever got injured. You see?
But I am in a very plaintiff friendly state. YRMV.
