Plus there could be a liability issue if there ever were to be a claim resulting in an injury.

@Ryan Fernholz @Thomas HickeyI just got sued( letter from tenant lawyer ) for this same exact problem, tenant attorney letter claim handrail was broken and stairs slope too steep...cause multiple injuries including fracture to arm. 

I've been operating my business from Europe for a few years because my son has been getting intensive therapy here for some injuries he sustained at birth.  

Personal Liability: For claims due to Bodily Injury or Property Damage that you becomeLiable for and which is covered under the policy.

Umbrellas are typically bodily injury and property damage oriented and don't cover the professional liability that comes with being a landlord.

To add insult to injury she and her boyfriend left a small junk yard out on the tree lawn and I was cited for it by the City of Cleveland, Ohio.   

It sounds good when the salesmen push it over the phone, but believe you me, there's no judge in American who won't hesitate to rule against you if you as a landlord obviously caused the tenant some form of  injury and the LLC is obviously just there to confuse the issue of who owns the property and is liable for any overlooked maintenance that caused the tenant's broken leg, etc.An LLC is not an insurance policy.

Did play fantasy football, and with my luck, player selections and injuries the past year or two, I might as well be playing the lottery - luck hasn't been much better!

@Taylor Angel Although your scenario of a contractor injury is extremely unlikely, an umbrella policy is also a very simple solution to an LLC or multiple LLCs. 

Thankfully the only injuries I have are due to him having to pry my purse from me and me falling to the ground.
