But Disney hasn't been exercising ROFR at all (except for BCV), and the foreclosure issue isn't exactly new.
I agree on both counts.
Foreclosures most often occur when buyers don't have enough equity to sell the property outright. DVC doesn't need to exercise ROFR on foreclosures--they simply take the points back. The only "cost" to DVC associated is writing off the debt that was still owed by the previous owner.
Besides, there really isn't any justification for DVC dabbling in resales at this point. DVC is sitting on a surplus of BLT, AKV and SSR points that could take them 3-4 years to sell. Sure they could re-purchase SSR points at $60 and potentially sell for $100 or more, but when they already have hundreds-of-thousands of SSR points available to them, it makes no sense to aggressively re-acquire more.
Once BLT is "sold out" there's a good possibility DVC will pursue ROFR as they are currently doing on some BCV contracts. They may even ROFR some BLT contracts now at the right price. But not SSR or AKV.
