How to structure this deal w/o money

[Christopher Morin]

I've found a wholesale deal I'd like to add to my long-term portfolio.  Problem is, my capital is locked up in a flip.  I do have an investor that I think would like the deal very much.  The wholesaler is marketing at 55k. Great condition, newly renovated, it's the right type of property at a discount. So I figure there are two options for me.

1) Wholesale the wholesale:  I take the 55k from the wholesaler, could turn around and assign that interest for 58k to my private money, and walk away with the quick cash.  This is fine, but the property really fits my long-term criteria; I like this option less.

2) Create an LLC and buy the property at 55k. Give 100% ownership of the LLC to the private money, but create an option for me to purchase ___% of the LLC at ___% the current valuation (55k). This more or less just extends the timeline to come up with the needed money myself, but keeps the private money w/ a piece of the deal.

What are your thoughts?  Can you assign a contract twice?  If you were the private money and the cash flow was there, would you like this structure?
