Unless you can show that a tenant was responsible for any explicit damage or issues caused by negligence, then the landlord is responsible for keeping the apartment maintained. 

The points you get on your card should cover the cc fees from the contractor or at least be close enough that it’s negligible.

Would you be OK with it if he could say, "Hey, I paid $300 and filed for an LLC, so I can be as negligent as I like!  

To not screw face frames together is more than negligent.

I did not pay attention to the fine print of the inspector report and I was negligent on the inspection myself. 

IMO (non-legal, naive opinion), If any issues were to arise, you could claim due diligence and best effort as a defense as long as you were not negligent. 

(probably not).You might be able to mitigate some of that risk if you could meet the owner and assess their circumstances before buying the property--but even then, your assessment is likely to be pretty hit-and-miss (although some people experience significant hardship through no fault of their own, it's not uncommon for people to create a fake sob story to cover up their own negligence/incompetence...even if you could talk to the owner, how would you be able to know the difference between legitimate hardship that was no fault of their own vs. a fake sob story?) 

The liability comes in when the landlord does something negligent such as knowingly allow a felon to keep firearms knowing they are legally prohibited from having them.

Difficult to impossible to price in tenant negligence and destruction.

  :)The LLC does NOT protect you from liability for your own actions (or negligence).
