Paying self or making money upfront on flips when working with capital partners?

[Nate J.]

Have a good history of doing flips but had some serious health issues which caused me to be out of the game for a few years. When I've brought in capital partners in the past we split the net profits when the property closed. Due to the situation, I'm not in a position where I can wait 3-4 months before getting paid.
Wanted to know if any others had any fair ways to structure getting paid upfront or throughout the remodel process that would be reasonable to a capital partner.
