All resale offers must be approved by
DVC before they can be closed. If DVC feels the offer is too low, their Right of Refusal allows them to purchase the contract at that price. The seller can't lose, as they will get their agreed to price, but the buyer could lose the purchase.
I understand that DVC has allowed the offer to be raised if they would buy it back, but don't know if that is always done. The latest "floor" for resales seems to be $58 per point.
