Final update!
Sent to ROFR: 1/22
Passed ROFR: 2/14
Closing time: 1 day
Deed recorded to contract showing: 22 days
Contract Showing to points in account: 1 day (did not call MS)
I emailed the closing company after 20 days post deed recorded date, worried if
DVC MA did not receive the deed or something bad happened. Not getting a confirmation, surprisingly, I received emails from DVC MA one day later on Saturday 11PM. I was about to wait for 24-48 hours before calling MS to get the points loaded, again as a surprise, points became available the next day!
I finally got the rooms of the first half of my trip booked, after renting the second half weeks earlier, which turned out to be a great decision as it's already booked out.
Total 62 days.
Overall, it's not too long. If the seller could have signed the contract earlier, the number of days would look a lot better.
