Seller does not have deed, but wants to sell land

[Bryan Blancke]

I got a lead from a mail campaign from a motivated seller. He wants to sell me six different properties which are raw land. The seller said he doesn't have the deed for these so I am not sure if I should even bother to look into the properties to decide on making an offer. The seller doesn't know how or what to do and I should be able to guide him through the process, but I don't know either. Do I tell him to get a quit claim deed from the actual deed holders before investigating the properties?
