@John Reyes sounds like an accident waiting to happen.

So is getting them to get additional insurance for any accidents good enough to cover me against damages or accidents or do I need to just let them know they can't do that business at the home?

Unknown problems might occur and you can't close on the triplex.

But likewise never not do something you know to be right just because it may be questioned.Something like you describe can be a very fortunate accident when it happens once. 

Something occurred to me today as my neighbor just sold his home for 200k more than he paid for it 18 months ago... beware of the cashout refinance. 

The problem usually occurs when someone buys an older property for 1/3 the cost of what it would be to rebuild brand new.

The bypass occurs when you mix personal with the LLC.

When a margin call occurs, the investor must choose to either deposit more money in the account or sell some of the assets held in their account".

Certain parts of your system might be things that it would never occur to anyone to do if they didn't start out from the perspective of managing from afar - for example, a house cleaner will usually be happy to do a "deep clean" twice a year and do an inspection at the same time so you can stay in control of the physical condition of the unit.
