There were several of us that purchased DVC during the pre-sale incentive, and none of us paid interest, payments or dues until the stated time, which was April 04 (or around that time) Many put the balance on a rewards card and paid it off before the interest and payments kicked in. This was through DVC financing.
A pre-sale incentive is different as those points are not in inventory and cannot be used in Phase I until Phase II is declared.
It may be incorrect for your situation, but not an incorrect statement as to what DVC is currently offering. Don't want to be nit picky and Im sorry that you had that experience, but this is the current offering.
My UY is March. My guide stated that I will not have to pay interest, payments or dues until March 05. Not sure how later UY's will be affected as I didnt ask.
The contracts and POS they send out do state when payments are due.
