How wholesaling with little money works

[Nathan Barshinger]

Hi everyone, I've been researching wholesaling lately and I want to give it a go within a month or two if it's true that you can wholesale with little to no money out of your own pocket. From what I understand, you leave an option window in the contract between you and the seller to find a buyer and if you find a buyer, you sell them the contract? Also if I wouldn't be able to find a buyer in that given amount of time, would I be able to back out of the deal with no penalty?

All answers are greatly appreciated in advance!!!
