fair split on a 3 way fix&flip if you the person with the money?

[Dominique Flipping]

I guy I meet through a friend called me and ask me to partner with him and another guy on a house to flip. they have flipped several properties. This would be my first. they have found the deal and have done the inspections. I will be putting the cash up for down payment and rehab which would be 30k out of my pocket.  for a 40, 40, 20 split. I would get 20 percent. I think it should be split even? or would 20 percent be fair since I didn't do any work and will not be doing any work?
