wholesaler question

[Ryan Watson]

ive been pondering on this for a while. I understand the idea behind this and how you come up with your numbers. However the thing i have yet to grasp is how do you get paid for jumping in the middle of the deal? What guarantees you will get paid? What is stopping the buyer from cutting the wholesaler out of the middle of the deal and dealing directly with the seller? can someone clear this up for me?

If i understand wholesaling correctly, the wholesaler does not have title to the property, so that is why i ask.
