Private Lending: What information do you require from a borrower?

[Steve Hiltabiddle]

A question to experienced private lenders, what information do you request from your borrowers as part of the vetting process?  What specific personal information do you request that borrowers typically don't have an issue with providing.  Do you run credit checks or request your borrower provide a recent copy?  How deep do you go or not go in gathering information?

Thanks,
Steve
