I am a DVC owner who has rented and transferred points and here is my response to some of what I skimmed from this thread:
1. There is no policy as to whether or not you "can" make payments. You are renting from an individual person and it's entirely up to them. I, personally, would not accept anything other than a 50 percent deposit and then the balance one month later. The renter making the early reservation has to put the money up earlier this way than if they paid Disney or a
travel agent but they are renting a beautiful resort at a fraction of the cost compared to paying Disney for it directly.
2. Once the reservation is made, the points are gone from the owners account. There's no reason for them to not have the points nor the money. Not many renters would be willing to finance your reservation over a period of time.
3. As for PayPal, I accept PayPal as long as the renter pays the 2.9 percent PayPal fee on top of the points fee. PayPal is a convenience to them and the points owner shouldn't lose 3 percent on the transaction.
4. This may sound restrictive or selective but the DVC owners have invested a lot of money into DVC and pay monthly dues for the right to be DVC owners. Having some extra points to rent out greatly benefits non-DVC owners since Disney charges such a high fee to those folks who pay cash directly to them.
5. As for point fees, the lower costs are for "distressed" points that need to be used right away. While it might seem appealing, the chance of getting a reservation is very slim. DVC has become so popular, even at the 7month window, during even non-popular time, I have found there to be no availability.
6. Points that can be used far enough out to have a decent chance of actually finiding availability are running about $11-12 per point.
I hope this info helps!
