I was actually in the process of buying a EOY CWA resale contract a couple years back. So they do exist. The contract was in Wyndham's hands for transfer, and they decided that they needed one more signature from the seller before completing the transfer. Unfortunately, the seller never responded. (It appears they were selling because they decided to move back to their home country and had left the USA by that late in the process. So the sale fell through because Wyndham wouldn't complete it without one more signature despite all the notarized paperwork. So Wyndham got some points back eventually because no one was paying MFs on that contract any more.)
