WHO PAYS FOR CLOSING?

[Lamarcus Stephenson]

So, I have an 11 unit Apartment Building with all occupied units under contract. Today, I'm assigning the contract over to the BUYER, but he's suggesting on signing, getting it notarized and then sent back to me. Is this his way of saying he's not paying for closing cost & fees....or do I pay for closing? Answers please? Also, I've already signed and notarized all documents on my end.
