Flipping without using your own money

[Belliny Flores]

Hello BP community. I'm a complete newbie looking to take the dive and looking into all avenues for financing for my first flip or buy and hold. I keep reading and hearing of purchasing without using your own money but how much truth is there to that? Is it only in a perfect scenario? If so, what would that scenario be? Or is it only with private investors? Or are there actually lenders that are willing to lend 100% of the purchase plus rehab costs? Any advice would be greatly appreciated before my first plunge.
