Paying for a GC for a flip

[Elizabeth Beard]

I just bought my first fixer upper to flip and now I’m trying to find a GC. I’ve been calling around to leads I’ve found. One asked me today how we planned to pay him. I always assumed a cost plus model but he said that GC’s are too busy and it’s not enough money unless they can be 50% partners on the purchase and the flip. What are best practices for paying a GC for a flip? Any recommendations on finding a GC who’s not going to take me for a ride?
