How much does your private lender require you to put down?

[Jason Martins]

We all know that most Hard Money lenders will require 10-30% down payment on a deal just so you have some "skin in the game". But do find that private lenders are different?

I have used a private lender that has not required any down payment so I have gotten 100% loans for deals. I know not all private lenders are that generous. I'm wondering if anyone else has had the same good luck with private lenders and if not, how much "skin in the game" have your private lenders asked you to put in on a deal? 

Thanks!
