Best Way to Partner?

[Jackson Tate]

I'm looking at a couple vacant sites in my area that will support the construction of duplexes.

I have a GC who would be interested in partnering and would be in control of the construction aspect.

What is the best way to structure a partnership for this kind of project, especially if we may do up to 4 of these at one time together?

Should I buy the land and then he supplies the down payment on construction? Any thoughts would be appreciated.
