If not, follow state law, your attorney general should have guidelines in a simple document for how to do this. 

Get things documented best you can, and file small claim against him. 

Zero clue unless they view copy and paste to opportunity overviews as violation of NDAs... which is ridiculous - 3rd parties would need to log in and sign their own to view any documents.  

Here are some expenses that you haven't mentioned:- Vacancy allowance-  Insurance- Property management - Taxes- Utilities (you seem unsure)- Maintenance- Capital Expense Reserves8.

Hard money will be the quickest with the least amount of documentation from you.

I understand there are flood maps on the FEMA website and the need to buy flood insurance.

Its much better to lose $100-$200 a month on a property because rent is low, than it is to lose your entire mortgage payment, insurance, tax, maintenance, etc because the property is vacant. 

We think this qualifies as abandoned but my more immediate question is if we have extensively posted the property should/can we insure it?

I am in the process of purchasing my first property and I really under-estimated the insurance cost... 

Get the house subject to existing financing (using line 203 of the HUD-1 document) and take over making payments.
