How much of your own money is required??

[Issa Rice]

Hello as a new investor, I find that I don't ask as many questions as I should, in fear of looking stupid. But ignorance is a luxury that I can not afford, so here is my question. When dealing with a private lender, how much of your own money is needed? As a new investor, I want to know where I should be financially before seeking funding. Or am I going about it the wrong way. I know most banks want you to have at least 20% down, but does that apply with private lenders? And how concern should us new investors be with the interest rates? All feedback is welcome and appreciated. Thank you
