1st time off market deal

Greetings,
I'm a first-time investor working to go from 0-1 deals! I'm looking at a potential off market deal on FB marketplace. I'm unsure how to identify the property is ligament or fake post. I reached out to an individual selling a home for 45k, cash only. I like to do a BRRRR and flip it.

They are willing to give the lock box code after I have sent over a photo ID.  But claim they live 2 hours away and won't be present to show it.

If we want to move forward, then he will quit claim deed it over at the courthouse.  
Is this how it's normally done for off-market deals?  Any suggestions?

Thanks for your help!
