Starting out wholesaling with little cash

[Nneds Ubani]

Hello all! I’m a super eager wannabe real estate investor, my largest barrier is my lack of start up funding.
Lately I’ve been considering wholesaling as I’ve heard it’s sort of an easy, low-cost avenue for beginners. 

My question is: when wholesaling, after finding a great deal, do you need real proof of funds to the get the property under contact or is there a way to get it under contract, find a buyer and complete a double closing/assign the right to sell without actually having the cash for the property? 

Thanks!
