How do you guys perform due diligence on an absentee property?

[Mahmoud Y. Elhalawany]

Hey guys, how do you typically perform due diligence on a property If the owner is an absentee owner? I want to walk every property I wholesale with a GC so I can give a good SOW signed by the GC to my buyers. But if the owner is absentee/out of state how do I perform my due diligence? Should I just consider not mailing to absentees if my business involves using the GC to walk the property with me? 

Thank you for taking the time to read this everyone.
