Can a wholesaler please clear up this closing Question!!!

[Demetrus Gibson]

Im trying to get this right:
Can the end buyer pay me the full assignment fee of (for an example :4k Money Order )
and I walk away, leaving he and the buyer meeting at the title co.
Or does he/ she give me a deposit and the title co cut the remaining checks? With All THREE of you meeting at the title co?
If we all meet: then I, the wholesaler call my title co. set the appt and bring the contracts????
Thanks
Eric
