We're going to have to agree to disagree on this one. They started adding restrictions on resale buyers over 8 years ago, and that doesn't seem to have hurt resales at all. As a matter of fact, they are actually much higher now than even a few years ago - even with the new restrictions. The only place this might hurt resales is for Riviera resale buyers, but since there aren't any, we have no idea what the effect will be. If a resale buyer at Riviera doesn't do their due diligence and research the purchase, well, I personally have no pity for them. If the resale price is even just $100/point, a 200 point contract will still cost $20,000 - and if someone blindly spends $20,000 without knowing exactly what they are getting, well, then they have more money than brains.
I've been told by DVC that the new restriction is due to current owner complaints about not being able to book at the 7 month window, and certainly has nothing to do with "crushing" the resale market. Even resale buyers are spending money on park tickets, food, and merch, even if the only place they can stay at is Riviera. I completely agree with Disney on this, as there existed the possibility of hundreds or even thousands of resale buyers in the years ahead making it even harder for all of us to book at 7 months.
