No money down wholesaling?

[Jamie B.]

Typically we sign a contract, try and put a small amount down to secure the contract then shoot out the info to our cash buyers. Recently we've come across a few other wholesalers who've been using a non-cicumvent agreement then giving out the more specific details on the house, presumably without the fear that the house will be bought out from under them. However I'm pretty sure that if someone does buy it right from the seller your limited as to what to do, mainly try and sue. 

Has anyone come across any other strategies that they've used for smaller to no down payments but still be able to secure the contract and the property? 

I get that the negotiation with the seller is always an option, but I'm asking more about wholesaler to rehabber/cash buyer.
