Hard money details

[Ray Bontrager]

Hi, I am looking to close my second deal but need looking to use private or hard money. I don't have any good private money connections yet so have been checking into hard money. I talked with several lenders and trying to understand the number system. So if I get a hard money loan for 100k and pay 15% down, does that money that I paid down go towards that 100k when I pay back or not. And if they have, say, 10% interest. Does that have to be payed back on top of the 100k and downpayment?

Thanks for any help in understanding this.
