Short version is title/escrow will "close" and send the deed to be recorded (usually 1-7 days). Once recorded, the title company notifies
DVC. According to "current" timeframes - you are looking at just over two weeks for DVC Admin to set up your membership and/or contract once received (you will receive two emails from DVC then - with your setup info), allow a day or two for DVC Services to put the points in that account.
I mention "current" timeframes, because that's why we all follow this Closing Time thread - to see if timeframes are increasing or decreasing for current transactions.
