Land Lease/ New development

[Devon Moore]

New adventure for me. 
I was approached by a wholesale partner and flipper partners (whom I’ve done private lending for) of mine about me purchasing 1.5 acres to develop 12-16 single family homes on.
I would be responsible for purchasing land and getting it prepped to build. 
The developer will carry all the cost to build the homes and split the profits of the home sales with the realtor. 

So my question is I would do a land lease to the builder. Just in uncharted territory with how to charge my fees. 
From my understanding I would also make my money back on the sale of each home. 
I’m in my deep research phase before I tell them anything and information and direction would be very much appreciated.
