My research with the comps suggests a price of around 134k and after taking out .70 it equals a little over 93k and I told her ball park was around 90k for the house.

Problems: Mold remediation took 2 weeks longer than expected, bulkhead needed 3k of repairs that were not accounted for, someone stole our metal gangway that connected floating dock with main deck, electricity via temporary pole in the yard because city of jacksonville inspectors would not go into the house with mold inside it. 

What remedy do I have?

Since I've never really gotten engaged on BP (a failure I plan to remedy) I don't really know what some of the terms are i.e.

Insurance was called the following morning and we had a remediation company there this morning to start work.

If they don't remedy the action, then you can offer them to leave with no recourse.

The owner might ask you to pay for a $20,000 bathroom faucet or mold remediation problem!

Remediation "specialists" charge an arm and two legs for all this work, but if your insurance is paying, maybe that's ok with you, and it is certainly more "hands off".

I'm very interested, were you able to find an effective remedy?  

Remedies may be available, such as petitioning the court of jurisdiction to confirm ownership; however any legal action is usually a pretty large added expense.As others have mentioned, it’s almost a “classic case” when a person with little or no experience, knowledge or expertise in the real estate foreclosure/bankruptcy/mortgage world buys a property at auction.
