Wholesale a Wholesale?

[Account Closed]

Hello all! Hoping you guys can help. I am super noob when it comes to REI so please forgive my ignorance to this. Here is the deal: There are 4 actors---the motivated seller, wholesaler A, wholesaler b (me), and my cash buyer.

I was on craigslist and found a single family home that needs a rehab. I called the guy (wholesaler A) who informed that he already had the property under contact and he was looking for a buyer. So he is a wholesaler looking for a buyer to buy the property but doesn't know how to get buyers. I am very new to this and do not have the confidence yet to rehab. I did however do my due diligence and amassed at least 5-7 buyers for when I begin wholesaling. My question to you all is: (A) Can I wholesale the wholesale to my buyer? and if so (B) how would I go about it? would my buyer be paying both me and the other wholsaler? is there more paperwork involved then just the purchase & sign agreement and the assignment of contract? Has anyone been in this situation before? Please inform me as this will of course determine what I do next? 

Thank you.
