"Reservation" points are points used for a non-
DVC reservation (cruise line, other WDW resorts, Concierge Collection) which was later cancelled - returning the points to the account. They cannot be banked and will expire at the end of the current Use Year and can ONLY be used for another non-DVC option. They cannot be used for a stay at a DVC resort. I do not think they can be transferred but, if allowed, the restrictions would stay with them (no banking, non-DVC option only, expire at end of Use Year).
The only way to borrow points is when actually making a reservation. If that reservation is later cancelled, the points are returned to the account and will remain in the same Use Year as the reservation for which they were used. They cannot be banked, will expire at the end of that use year and they cannot be transferred to another member.
You can only transfer points from the current use year - if they were banked or borrowed into the current Use Year they cannot be transferred. MS does have the capability to track the original and current status of all points in our account.
Your option would be to rent a reservation made using those points to another member and ask that member to "pay" you with a transfer of their points into your account. You could also make a reservation and use it yourself or rent it to someone else for cash.
