The conventional wisdom I have seen is that as the year 2042 approaches, Disney will have to start dropping its price per point. While this may be true (obviously it all depends on supply and demand and how fast they INCREASE prices now), there is no reason why Disney can't continue to sell points at $100+ in 15 years or even 25 years. Dean said, "As the right TO USE approaches 30-35 years, sales will be difficult at current prices." I disagree. But keep in mind that in 25 years, $100 will be equal to about $50 today.
I know that no one is buying into this as purely an investment, at least not a "financial" one. However, if the price per point is so low relative to hotel prices, they may. Right now the cost is $72/point, and about $4/point as a maintenance fee. With Disney's "deluxe" rooms going for about $300, rental prices per point are $10. Means one can "rent" a DVC studio for about $150/night (assuming 15 points on average, 105 per week). Or, get a room at about half price.
One could buy 150 points for $10,800 today. Rent them to someone for $1,500/year. After paying the maintenance fee, have $900 left over. That is your "income". A few years from now, when Disney's room rates are say $360 (20% increase), I am sure that one could rent their points for $12. Assuming maintenance fees and rental prices both increase at 3% per year, in 2016 main. fees will be $935 ($6.23/point) and rental fees will be a little over $15.50/point. That means you could rent your points for $1,400 more than you pay in main. fees that year.
So, you pay $10,800, get back rental fees less main. fees each year for 41 years, until you have nothing left. Well, assuming all of that, your return would be 12.0% on your "investment".
Lets fast-forward to 2026. How much would one pay to get 150 points per year for 16 years? Well, by then main. fees would be double what they are today - $1,200 per year (assuming 3% annual increases). However, assuming Disney has raised their hotel prices by 3%/year (and they have done well above that in the past), a regular hotel room at Disney will be going for $600. So renting points at $20 each would still offer the opportunity to get a room at half price. So you could rent your points out and "make" $1,800 that first year. If one paid $15,000 for the right to get 150 points from 2026-2041 and rented them, using the 3% increase assumptions, they would have a return of 14% on that "investment". Even better than buying at $72/point today.
The person who pays $100 per point in 2026 and $1,200 in main. fees (more in the following years) will pay a little over $39,000 for 16 years worth of points. Add in some interest on their original purchase, and maybe they pay about $44,000 over 16 years. For less than $3,000 per year they can get 10 nights in a studio room, a room that at the time will be going for $600+. They paid, on average, $18.33 per point ($44,000 / 2,400 points in 16 years). But I'm pretty sure that getting a room at Disney in 2026 for $275 (15 points x $18.33) will be a very good deal.
I'm not saying that there won't be a "DVC II". But given the fact that Disney room rates will continue to increase, and thus rental prices will continue to increase, the value of a price per point at DVC will increase into the future, even when there is only 25 years or 20 years or 15 years left. And this means great things for those current owners who wish to sell in 20 years. I'd be willing to bet that you will get more than what you paid for it.
