How do investing/partnering work?

[Hussein Al-asadi]

Let say i find a good flipper whom have a good record, and this flipper need money to flip houses. If i provide the money how does the deal work? Do we split 50/50?

Can i get into these kind of deal from sweden or do i have to be in the US?

If anyone knows how i can get into these kind of deals it would be of great help :)
