Wholesaling on the MLS? (North Carolina)

[William Maddox]

So, kind of a weird question. I'm fairly sure of the answer, but double checking.

I'm currently working with a friend of a friend, who does everything from flipping, to owning rentals, etc. He's been a big help at helping me analyze deals, and has helped market properties with me to his cash buyers, which is fantastic. He emails me yesterday and asks if I've ever considered listing a property on the MLS with him since his cash buyers haven't shown much interest in that property yet. This is just a standard assignment of contract deal, of course, so my question is throwing an assignment of contract on the MLS is surely illegal, right? I would love to understand this situation more, if anyone can help.

Thanks!
