The seller still holds that toxic asset 8 months later. 

Check with the agent if there are any disclosures on the property.Is it sitting on a toxic waste dump?

I'm going to be a bit irritating but I'll say it anyway. 

She spoke with the listing agent and felt that the "good ole boys" in the commercial space would be very difficult to remove, possibly causing some sort of retaliation on the property, the house needed a roof replacement which I did not see due to the snow when I was there and because of the 70 history of the commercial space she felt the property was toxic with who know what was being dumped there. 

another example of why need to do environmental due diligence for non-industrial properties. even farms can be contaminated. https://www.nj.com/ocean/2019/11/this-rural-nj-paradise-was-almost-destroyed-by-toxic-chemicals.html
