How do I start private lending?

[Travis Darden]

Hello all, I have a question about how does one become a private lender?  I have some resources that I would like to use to make some passive income.  What are the usual terms?  How many months is normal?  What happens if they don't pay you back?  And the last item that I really need to understand is how much to I charge to loan out my money?  Any advice would be greatly appreciated.
