No monorail is a biggie.
But the bottom line is that I just don't see the financial sense of purchasing DVC. I've thought about it a dozen ways, and since I wouldn't be able to pay cash outright -- I'd have to finance some -- the reality is that it makes no economic sense.
The reality is that the rental market is just too robust to make purchasing economically feasible. At $10 or even $9 a point for rentals, the "savings" that you realize as an owner paying $4 plus per point per year is about $5 to $6 per point. At $5 a point, it takes many many years to justify the cost of the points. (Say they are $85 per point -- that's the equivalent of paying 17 years of prepaid points. If you're also paying interest, tack on 7 to 12 more years.)
For example, suppose I want 200 points at BWV, and I get a smoking resale deal and disney does not exercise ROFR. At $85 per point, plus closing costs, I would go out of pocket about $17,550. Let's say I can put $7,550 down, but need to borrow $10,000. That's $700 more per year in interest for the first few years. My maintenance fees are about $770 a year. So I'm out of pocket $7,550, and I need to pay off the principal on another $10,000, plus $700 in interest every year. Or, in short, I'm out of pocket $17,750, plus $1470 each year (in interest payments and MFs.)
To rent 200 points each year costs me $2,000. So by purchasing, I save $500 each year -- which would take me over 30 years to recapture my investment. This number will go up each year as I pay off my loan, but even when it's fully paid off, I still only save $1230 a year. Even at $1230 per year, it takes me 14.3 years to recapture my investment -- and then I recapture it only if I use every single year and never let a single point lapse. If I rent my points one year, I'm just treading water.
Purchasing a timeshare that has an expiration date with a break even point of 15 to 30 years simply makes zero sense to me. The only justification I can see is the "owning a piece of the magic" justification. I fully respect people for whom this is a motivating factor -- but it's important to realize that this is why you're doing it.
Now, there are a few problems with my scenarios. (1) They assume the rental market will always be as robust as they are now. It could, of course, change, but currently you can pretty much get whatever you want on the rental market. (2) You absolutely have to be in a particular home DVC resort, and there is a danger that without the 11 month reservation period, you won't be able to rent that resort. Again, given the rental market and the ability to line people up 11 months in advance with the home resort you want to start calling, this is not a concern at present, but emphasis on "at present." (3) You have the personality that can stand doing rentals each year. Again, if this is not you, then forget everything above. For me, the trade off of dealing with renting every year is easily overcome by the flexibility of renting. You can go when you want, where you want, last minute, etc. You don't need to worry about banking, or not using points, or renting them out to others (which is a much bigger pain in the neck than being the renter).
Anyway, sorry for such a long winded post, but you asked . . . :0)
