My dad will invest if my sisters work together to start a company

[Alex Schar]

My dad wants my 2 younger sister and I to work together to start a real estate company, he says he wants us to start with 2 flips then we can do what we want with that money. Any advice? I find my sisters immature, pretty nervous to work with them. I’m more interested in rental, but we’ll need money from somewhere, how should we start, do we need a contract? How do we find a mentor? I know little about real-estate from bigger pockets but they know nothing, just that they’re interested in real-estate
