Putting my building construction background to good use.

[Steven Yeater]

My boss at one of my jobs buys and flips homes on the side. I've made him aware that I'm capable of replacing and repair everything in a new house he purchased. He offered to pay me $10/hr to work on the house. I'm trying to come up with a counter proposal involving compensation based off of either a percentage of the sale price or the rent. The house was purchased for $650 and I believe after I fixed it up it could sell for about $16000. I've estimated the materials for the house will be $3000. Has anyone ever tried something similar? And if so what percentage was agreed upon? Any and all information would be very helpful.
