I would contact the seller as well. This is a unique situation. For you, the "rules" did kind of change mid-stream. And yes...the agent DOES work for the seller, and they get paid whether
DVC gets the contract, or you do. The agent is DEFINITELY the one who gains the least if your counter is accepted (10% of $500 isn't much, and they have to re-write, and re-submit the contract). The seller is probably unaware of DVC's new "pricing policy", and would love to take more money if that becomes an option.
The only person I know to offer a counter was Calypso-a-go-go. Here's the thread:

There's not much detail there, except that there was no "broker" or agent involved. I remember that I was new to DVC at the time, and he and I had some talks about this...I was repeating what my agent had told me about how sellers didn't want to wait 30 days, and he/she kept saying that theirs was THRILLED to wait. That made me think...maybe it really IS the agents who do not want to wait...maybe they never DO present the counter to the sellers. I hate to think that. I used TTS and they were SOO nice...but, they were NOT working for me!!
All I can say is this...if it were MY contract...I would do everything I could to keep it!! The worse thing the owners can say is "no"...and, then you are NO worse off than you were before. But, if you don't try...you will ALWAYS wonder "what if".
On a good note...someone just passed BCV @ $72 per point. Maybe DVC is not being as "aggressive" as feared...maybe they just want to "buy low and sell high" to increase their profits!!!
Good luck in whatever you decide,
