I would add:
b) Since you are thinking of going during Epcot's Food & Wine Festival, I would think BCV could be difficult to book because it is small (not a lot of rooms) and it is near Epcot. Is there a reason you have ruled out BoardWalk Villas? If you want to stay at the Epcot area, it's bigger (has more rooms) than BCV.
c) Renting at 11 months would mean finding an owner who both has the correct home resort and who has enough points they don't need for themselves. Someone might have BLT as their home resort but not have as many points as would be needed for what you want to book. For example, a lake view one-bedroom at BLT for a week in October is 241 points.
d) I have never tried to rent points, but if you're trying to do it at the 11 month mark, I'm not sure how it would work if your first choice is one resort and your second choice is a different resort. If someone is trying to book for you at 11 months, they can only book at their home resort. I don't know how likely it is that someone would have enough points at two different home resorts, so that if they couldn't get your first choice they could switch to your second choice.
e) I don't know who came up with the buzz line of renting
DVC points so that you can stay at a deluxe resort for the price of a moderate, but that person is very good at marketing. In reality, it sometimes to leads to people comparing the rack (un-discounted) rate of a moderate versus the cost of renting something which has very limited availability, such as a value studio at AKV. It ignores the fact that sometimes Disney will have discounts for its regular hotel rooms, or free dining. It also ignores the fact that the DVC villas with limited availability are hard to rent.
f) So in order to get what you want, you need (1) an owner who has the correct home resort, and (2) who also has enough points, and (3) who is willing and able to go online at the correct time on the correct date to try to make the reservation, and (4) who is fast enough to book what you want before other people book it.
