I think it depends which property & amount of points your purchasing. For several of the properties, the spread between direct & resale is not as significant as others. I never contemplated going direct, but as I've been looking into this a bit closer, my valuation of the "perks" has increased. Most people focus on the "blue card" perks, but forget/ignore that with the new resale restrictions there is a second, and probably more significant benefit of going direct.
Resale points cannot be used at any future
DVC resorts. Right now this is not a big deal because there are currently zero resorts that DVC owners cannot use their resale points at. Soon Riviera will open, and a few years later Reflections will follow. Over the life of the contract 23 to 50 years, there may be many more new resorts that will open and resale purchasers will never get to try any of these. Factor in that in 2042, 5 of the original 14 resorts will fall out of the system. By buying resale, you are really limiting your future use. You really have to determine how much money you truly are saving, especially after things like prorated first year maintenance fees, credit card points on the purchase, automatically getting a loaded contract, and savings on annual passes (even if it's only one time before the perk disappears). Not to mention the pure ease of the transaction.
Imagine if you were offered 50 annual passes (one for each of the next 50 years). You had two options. One would act like a normal annual pass, but cost an extra few thousand dollars upfront. The second option allowed you to go in and walk around all of the parks, and go on all the current attractions, but never try any attraction built from here on out. When an old attraction was replaced, you would not be allowed on the new attraction either. Which would you choose?
