Wholesaling Inventory? How Does That Work?

[J'Nelle Lake]

I'm having trouble understanding this concept. I could be missing something, so I'd appreciate the help. 

I was asked by two buyers that I send them my inventory. I was clear that I was a new wholesaler and not a buy and hold investor when we first got in contact. 

As a wholesaler, I know we have a seller's list that we go through, we contact, and try to get deals out of that list. If I don't have buyers lined up for homes, how can I have an inventory? 

Are they asking to see the list of homes I have under contract? Would that be my "inventory"? Is that even smart to have a bunch of homes under contract not knowing if you could sell them all? How does that work?

Thanks in advanced for your help guys!
