I'm willing to put some of my own skin into the deals so you know I mean business. 

@Britany Woodman I think what @Jesse Gonzalez said would be a good way to go, get a brand new SFR with really no skin in a the game.

None of the below will matter to you at all if your real estate holdings are on top of very healthy/hefty retirement accounts.

More than one way to skin a cat!

I ask the question because this could be a strategy to get Seller to have skin in the game for the assignment and work with me on price and it still allows me to reserve downward negotiation on the wholes sale price. 

I think the only way I would go back to hiring a GC would be if I made them a partner in the project so they had skin in the game and we were all working toward the same goal.  

Regardless, I've not met a private lender who would entertain lending to someone with no track record and no skin in the game.

What amount of money down (skin in the game) would investors be looking for from the developers?

What are some ways you can structure a partnership with contractors to ensure some "skin in the game" with buy and sell properties?

If I were the investor I am not sure if I would go for this kind of a deal because I would feel the other guy (me) doesn’t have any real skin in the game.
