Any timeshare should not be looked at as a financial investment that will garner a return on that investment, other than saving you some money on your trip via lower room rates.
With all due respect, while I understand that buying a timeshare is not an "investment", paying attention to resale value isn't foolish. When you buy a car, you don't expect to be able to sell it for a profit or "return on investment", but you would pay attention to what kind of resale value it may have in a few years and your decision on what car to buy may depend on how well that car keeps its value. When I bought into DVC, it had a many year history of good resale value (demonstrably better than its competitors and much discussed on TUG) and that was a consideration (not the largest but a consideration) over buying a Marriott timeshare in Orlando as was the fact that resale purchasers were treated the same as direct buyers.
At that time, BVC and BWV resales were selling for more than direct sales from Disney for SSR and Disney did not have inventory for all use years for those resorts. The consistent and overwhelming advice on these boards was to buy where you want to stay even if that meant paying more to buy resale for those resorts than buy direct for SSR. So while I understand that some of the posters on this thread feel that resale purchasers get what they deserve for buying at a discount, that wasn't necessarily the case for resale purchasers.
It is disturbing to contemplate that additional changes could include removing the ability (or "perk") to transfer to other DVC properties for resale purchasers. If direct purchasers could transfer into a resort but resale purchasers could not transfer out, there will be resale owners who won't have any ability to use their timeshare interest at all for certain use years. For example (and I exagerate to make the point), if twice as many direct purchasers wanted to trade into BVW than wanted to trade out, and resale purchasers were not allowed to, then demand for BVW will exceed supply and a lot of people are not going to get reservations at BVW that year and some of those people will be resale purchasers who have no ability (perk) to transfer to a different resort. At some point, that makes the resale value of a DVC interest no better than a lotto ticket (and again, I exagerate).
I'd really like to think that I would hold on to my ownership interest till death do we part (and I'm not rushing to that finish line), but I would feel foolish if I didn't at least contemplate the possibility that I would have to or maybe want to sell my ownership interest. Oddly, I think this change if it happened before I bought in would have made me more hesitant to buy direct than to buy resale. Much like the car, if it is going to lose value the moment you drive it off the lot, it makes buying resale where that loss is already priced into the car, alot more attractive.
Just my take.
