You mentioned that you found the deal by accident of sorts so I'm going to assume you also invest in MF as per your other comments.You don't really say what the percentage breakdown is of the physical space e.g.

I`ve been a General Contractor for 34 yrs...........and believe me there are enough "Johnny Lunch Box" Licensed contractors out there that don`t know squat and do horrific work.Keep drinkin`

Not having adequate insurance for a property investor can be a disaster that is one freak accident away.One of my clients had a rental property that caught fire due to a tenant’s over-heated laptop left on a carpeted floor.

You can purchase varying degrees of deductible coverage (depending upon what you as the Broker might want to handle) before the E & O Provider steps in to cover the balance.Consider it similar to you being involved in an Auto accident and you would be responsible for the first $500 or $1000 dollars of the damage (deductible) before your Insurer steps in to cover the rest of the damage. 

If you buy a house with and "illegal" addition insurance companies will not cover the addition and in some cases wont cover the entire house and they might not cover an accident caused by the addition like bad wiring causing a fire or bad plumbing in the "illegal" addition that causes damage to exiting structure also if you sell and don't get the addition permitted the square footage wont count towards the sell price or they might count it if the addition looks good and has a good flow but for half of what sq ft is selling in the area. 

Our only international investment is in Costa Rica, and we bought the surrounding vacant land in order to make sure those lots were developed in the best possible way for our property, so ended up developing a bit and creating a nature preserve kind of by accident.

For the Personal Property Coverage, yup I don't have anything valuable items in there.For Premises Medical Payments, isn't it good to have this coverage when accident happen?

Same if I get sued because of an accident or incident on one of my properties, I am protected correct?

Our contractor got into an accident and is now unavailable :(. 

I plan on setting up another tab to keep track of when "out of the ordinary" events happen (transfers from me into the LLC, if I accidently pay for an item with a personal credit card, etc).
