Generally, I don't think rofr activity would directly have an impact on how much I'd be willing to pay. But if overall resale prices increase because others are paying more, I'd probably have no choice but to follow if it was something I really wanted...
I'd be more interested in he characteristics of the contracts that were taken at rofr. For example, was any stripped contract taken, or were they all loaded? If they were all loaded, then nobody should pay more for a stripped contract, even if the broker encourages then to do it "because of rofr activity". Similarly, did they take any subsidized contracts, or were they all unsubsidized? Does having prior year banked points on the contract (for which the buyer doesn't typically pay dues) increase the likelihood of a contract being taken?
DVC resale prices are still substantially higher than other timeshare systems. There is no way they can make 4x or 5x consistently from recycling rofr inventory like Marriott does. At current prices, it doesn't really move the needle that much. They also still have plenty of new inventory to sell, with more in the pipeline. So there may be some other common factor driving these decisions.
