Can you sell homes before they are built using buyers money??

[Demarco Matthews]

So me and my wife own some land that we are in the process of building our home on and think we have the perfect place to develop estate lots. 

We are trying to figure out is it possible to play "home builder"?  Can we sell new construction to buyers and build (on buyers dime) the homes as each lot is sold with our general contractor?

With our resources and building at cost it looks like there may be a large profit margin here. I cant find anything or anyone who has done or attempted this strategy (selling before building).  

Look forward to hearing you guys thoughts.
