I appreciate Mark Whitten's knowledge because he has been out here promoting wholesaling for a few years now but these guys who promote both wholesaling and creative financing using other people's money oversimplify the entire process which can mean big time struggles for the listeners.
The wholesaling guidance never goes into how quickly you need to move once you extremely lucky enough to find a property far below market value, get a contract with the seller and then assign that contract to another investor. The questions are how long do you have the contract without paying any earnest money down nor the liquid cash to outright buy the property? And what happens if you can't find a buyer for the property but you have already signed to purchase the house? Without good contacts with cash investors saved in your phone... it seems very likely that the wholesaler will default on the contract.
