But if the property is in an LLC and you've operated it correctly (look up how to avoid "piercing the veil"), then the damage would be isolated to your equity in the LLC.

As I understand it the LLC helps to isolate 1 rental from another so that a lawsuit from one property cannot get to the equity in another property.

Older houses noise isolation can be an issue.

But, after a while I realized I couldn't really isolate a value difference for that amenity.

Per our conversation when you were last at the house looking at the fridge, all of the door seals appear to work properly and there is no obstructed air circulation or items pushed against the walls or rear which would isolate freezing (each time freezing and thawing has occurred, it does so throughout the fridge, not just in one area).

As I recall, usually these investors get a less than 5% controlling interest in the LLC to keep them passive and the Managers actually form another LLC to run the operation --- this isolates their liability.  

It certainly is cheap and possible to have an easy life but kinda isolated.

In your case, potentially the main value, from an accounting / money flow aspect anyway, in my layman's opinion to having a holding LLC would be to isolate any capital flows to just business accounts. 

There are still 1-2 isolated problem houses remaining on the street to this day, though the police department is keeping a close eye on them.

Am I SOL?
