I would assume that resales for other timeshares are quite more problematic than those at
DVC. Overall DVC resale is a safe purchase, in that the value is high and maintains itself, but other timeshares are miserable and even resale buyers can be enticed by the near 0 prices
only to learn of the restrictions post purchase. Where DVC is a substantial investment on resale so buyers think about it more before pulling. So it doesn’t seem as important for DVC resale agree.
So the law was created to protect all buyers likely. Hard to craft a law that isn’t equally applied.
