However, insurance is limited because it only protects you from one type of liability: accidents/negligence.

I did a research project early this year, the data (especially H2 2016) showed O&G total employment figures were flat (negligible changes in hiring/firing) while other industries were growing & adding employees.

Liability insurance is a great help, but you never know if the company that writes the policy will try and deny any claim due to negligence on your part.

Your price may increase the overall tax base but the change should be negligible.

@Jennifer Tung having a mortgage is a negligible barrier point as a seller.  

If $43,949.19 is negligible to you, then you are absolutely right and considerations for interest paid is nonsense.

So even if you record the transfer with a nominal amount (such as $1 or $10), the transfer taxes won't just be negligible. 

At some point the added competition for assets really has a negligible impact on pricing anyway.

In the first case I am negligent and in the second case I am not.If I hired an experienced, reputable PM what can I be held liable for?

As long as you have liability insurance you should be alright, and unless the property was not properly maintained or you did something negligent it should not be an issue.
