There are other factors to be considered here. For one, the age of the member. Like myself and my DW, Diane and her DH are, let's just say, 'older' than the average member. Having a resort that doesn't expire unto 2057 could be meaningless. In my case I'd be 113 years old! (This is especially true if one's offspring aren't Disney fanatics and wouldn't be using the points themselves)
Then, let's say someone sells 150 OKW points and receives $85/point ($12,750). They'd get about $11,475 after commission. If they bought at about $65/point, then they would have a net profit of about $1725 which they would have to pay taxes on. So maybe when all is said and done they'd get about $11,000 total cash.
Then purchase 150 AKV points for $13,950, it means they would have spent almost $3,000 just to swap resorts. And if it is necessary to finance to make the new purchase, the 'swap' could means paying up to $4,000 or so.
That comes out to about $27/point to swap out. As for future resale, I can't even predict when the difference in selling price between OKW points and AKV points would ever amount to $27. That would be your 'break even' point, and could easily be 20 or 25 years or more into the future.
Finally, just guessing that since AKV will be a smaller resort than OKW, then like BWV, BCV and VWL, the maintenance fees will be slightly higher, which over time eats into the pocketbook. A difference of only $0.30/point in maintenance fees over the next 25 years, amounts to paying $1,125 more in maintenance fees for one resort compared to the other.
Finally, if one's travel plans can be very open, it'll be possible to get AKV rooms at 7-months, using OKW points.
