I know this has probably been asked a thousand times but, if I'm going to borrow points to make a reservation at my home resort I don't have to wait til the 7 month window to use the borrowed points do I?
Borrowed points are supposed to retain their original home resort status, so if you need them for a reservation made at 11 months, it would be wise to make sure they are for that resort - otherwise you may be sadly disapoointed.
DVC apparently has difficulty tracking transferred points, so you "might" be OK before 7 months with non-home points, but I'd sure hate to be disappointed if MS won't allow it all of a sudden.
To be safe, I'd try to find points from the resort where you want to reserve.
