Yes, but that buy in occurs for every
DVC member. Those small resale contracts are about equivalent to buying direct, but non-members can't buy those contracts direct.
Why are those contracts at a premium right now? There's already no benefits associated with them. 2/25 makes no difference to those contracts. The people buying them either buy as their only way in or to get a contract that Disney is not willing/able to fill (closed or long waitlists). That doesn't change with the new rule. In fact, with the increased minimum to buying in, more people will look to the resale market for small contracts and with the increasing prices the resale market will continue to increase in price as well.
