I think that it's mostly #1, due to a supply and demand situation - good economy means less people putting their DVC units up for sale, and more people wanting them. One factor that you are not listing - I noticed is that based on limited data from DVCresalemarket, that Disney is buying back a greater % of contracts in 2017 than 2016. (Their data says 2016 it was 4.4 %, while in 2017 its like 7.8% average.) Disney could possibly be leveraging the ROFR to elevate DVC resale pricing. It's a factor that really ONLY applies to DVC, as I don't think any of the other timeshare systems are really interested in buying back contracts. Disney has this ability to "control" to a degree resale prices - and that factor shouldn't be ignored.
