Here are the historical resale restrictions that have been created:
Pre-March 21, 2011: If you own any points purchased before March 21, 2011, whether new or resale, none of the following restrictions apply to them.
March 21, 2011: cannot use points from any resale purchased on or after 3/21/11 to reserve the Disney Collections (Disney hotels), Concierge Collections (certain non-Disney hotels), Adventures by Disney, or a
Disney Cruise.
April 4, 2016: cannot use points from any resale purchased on or after 4/4/16 to qualify for incidental benefits a/k/a membership extras, e.g., discounted AP’s, the DVC 20% merchandise discount, DVC dining discounts, Moonlight Magic or other exclusive DVC events. Note that if a member was subject to that restriction because the only points owned are resale points purchased on or after 4/4/16, the member could acquire access to membership extras by purchasing the minimum add-on point addition from DVD which, at the time, was only 25 points at most resorts. That minimum applied until 2/25/18.
Starting February 25, 2018: you need at least 75 points purchased from DVD to get membership extras unless already entitled to them as result of purchases made before 2/25/18.
January 19, 2019: any resale points purchased before 1/19/19 can be used to reserve any DVC Resort, including Riviera (and now VDH, on sale starting in 2023). Resale points purchased on or after 1/19/19 for any DVC Resort that existed before Rivera (and that includes any additions made to any such pre-Riviera DVC Resort such as at VGF in 2022) cannot be used to reserve Riviera (and now VDH) but can be used for all DVC Resorts that existed before Rivera. Any resale points purchased for Riviera can be used only to reserve Riviera (and now any resale points purchased for VDH can be used only to reserve VDH). It is suspected the same type of restrictions will apply to the Fort Wilderness Cabins addition and likely to the new Poly building (unless it is made part of the original Poly DVC)
Starting September 17, 2019: You need at least 100 points purchased from DVD to use membership extras unless already entitled to them as a result of prior purchases.
Starting October 19, 2020: You need at least 125 points purchased from DVD to use membership extras unless already entitled to them as a result of prior purchases.
Starting June 3, 2021: You need at least 150 points purchased from DVD to use membership extras unless already entitled to them as a result of prior purchases.
I have seen posts (and other websites) that have described the above 125 and 150 minimum purchase rules to obtain membership extras as also being the required minimum point purchase rules for any new purchasers. That is not correct. A new purchaser from DVD could choose to buy fewer points from DVD, as low as 100 and possibly even lower, but doing so excludes them from membership extras.
Exception for Gifts: A member’s giving, while living or upon death, an ownership interest to another -– relatives, friends, or anyone else – does not trigger any of the above restrictions based on the timing of the gift. The gift recipient’s ability to use, and the restrictions applicable to use of, the points for reservations or membership extras will be the same that the giving member had applicable to the particular ownership interests transferred before the making of the gift.
