appraisal look up

[Shequann Burrwell]

I have a lead in North Carolina. Already spoke to the owner and he is telling me that the property appraised for 150k. I have ran comps and did my research and the property is located in a high crime rate area and there isn't a single house near by the supports the 150k appraisal he says he had done. not even close. Its also a odd shaped lot which doesn't work in the favor of any seller.  Is there any way to look up the appraisal so I can make him a offer and get this under contract.?
