They will vary by resort. Be sure to find out all the costs involved so you aren't surprised by a stray fee. The seller may not even know them all, so do your due diligence.
Transfer fees also are negotiable between you and the seller.
For some resorts, the seller should be happy to pay them all. For others, you might split them.
It really comes down to the resort and how fast you want to get the deal done.
In the timeshare resale market you usually "pay" for your "free" or inexpensive timeshare when it comes time to sell it.
