How to know if A private lender is who they say they are?

[Allen Martin]

Hey, 

I recently posted here on BP about needing help finding lending on this MHP I am purchasing. I was contacted by A guy who claims to have a lender who wants to lend me the money so he sent over the lending documents in an email. Being cautious I simply ask "with all respect how can you prove to me this isn't a scam since it would be an easy way to get all my information" the response I got was "I assure you it is not a scam my lender is willing to give you the money..etc" the person name is Samuel Thomas can anyone vouch for him?
