It feels like I can either brush it off and close as planned (we're gonna gut the kitchen anyway) or try to turn this into a negotiation point to try and get some money back? 

It is better if you spray versus brush the cabinets. 

Unless you're right on top of Indian Creek or Brush Creek (both of which I'd avoid like the plague, as every time they try to make the situation better, it gets worse), the majority of KC is not a flood zone.

Start driving around and looking for filthy, nasty, dirt/locations, swampy, boggy, trees/brush, etc. 

@William AllenI misspoke - I had to brush back up on the legislation for this. 

Looks like I need to start brushing up on my negotiating skills and reference Chris Voss.

Thanks @Chris Seveney, #1 confirmed what I'm seeing.Yes, the plan now is to reinstate the 1st, leaving the 2nd and all other encumbrances in place, brushing up the place with $5K-$10K, and selling as is. 

Then the subcontractors I hire just have to pickup the misc. materials & consumable items as they need them (e.g. caulking, adhesives, screws, nails, drop cloths, trays, brushes, taping mud, etc.)

Brush it off and move forward.

I know that North Myrtle is vastly different but the media brush covers all.
