Equity in a deal in exchange for sweat equity

[Gabe R. Gonzalez]

What's the best way to structure a deal if I were only bringing sweat equity into the deal? I have an open offer to kick in some sweat equity for a larger multi-family deal, should I find something that works. 

How and when do I leverage that equity - is that only at time of sale? I'm not sure if equity is the best way to go about this if I can't capitalize on it for at least 5-years.
