How to buy Wholesale?

[Erick Jordan]

I am in the DFW area and looking for something to rehab or buy and hold.   I am having trouble finding any deals that have the room to make any profit on and am now looking at wholesale "package" properties that have a, what seems like, decent margin.  I just don't know about buying a property through a wholesaler???  It seems like an ok thing but there is no way for "Due Diligence" on my part due to the fact that it is a non-refundable down payment and a very short closing period.  What is the general feel for wholesalers in the DFW area and how do you all deal with them? 

Thank you for your input!
