I think for Hilton it works differently.
The buyer only has control of the points, AFAIK, if on the contract it was stipulated that the buyer gets the "current/previous" years points.
I've seen some cases where the buy opts *not* to take those (thus, not having to reimburse the owner for the MF) and Hilton simply removes them so the buyer logs in and only sees next years points (or whatever the case may be). At least every one of the 5 resales I've purchased, it's been listed what the points are for the 3 years, and what points you will get.
I'm not sure that ROFR has anything to do with that process but I could be wrong.
If the OP worked with a broker, I'd call the broker, otherwise, I'd call Hilton and they could tell the OP what the options are, if any.
