Hello so I just started learning about becoming a real estate investor and I wanted to know how exactly it works. I saw from successful people that they actually didn't put no money in and basically found a seller l, got a deal with them and found a buyer to pay more. With all that the middle person makes profit and the buyer fixes and flips it for more profit. I wanted to know more about how exactly to go about this if anyone can help me in this?
