I'm up in Canada so the rules might be slightly different, but generally up here if the roof is beyond a certain age (I think it's 20 years) you generally have to sign a roof waiver excluding the roof coverage.

I do not want this to be too complicated just want the right coverage and protection while building my portfolio.

You take a risk which could result in cancellation of your title insurance and complete loss of your real property without compensation in the event that a title issue regarding your real property arises.Contact your title insurance company to determine coverage and if your policy does cover transfers , and when or how. 

Next, you would want to go after the liability or "Errors & Omissions" coverage of the Broker that the real estate agent worked for.

For many years the data products out of the FirstAm lineage were superior in terms of coverage, timeliness and quality.

You want to see coverage for at least General Liability, Professional Liability, Workers compensation, and Business Auto Liability.

@Mike Wood is so correct all lenders will require flood coverage for under construction due to federal law.

A great insurance broker will help you get the coverage you need to sleep soundly at night.

@George Glessner the insurance coverage is no different for an LLC than it would be for a personally owned property.  

Examine the coverage (Special form is better than Named Perils), Fully earned policies mean that there is no refund if you finish early, and if there is Coinsurance have that explained to you by the agent.
