I'm sorry that some posts have led you to believe that you are "wasting" your points by using the other options available to direct DVC purchasers. Certainly there is a whole convenience/enjoyment factor that comes into play that cannot be measured by dollars and cents. It is on that ground that you can "win" the argument against those options being a "waste" of points.
Where you lose the argument, however, is when you try to use math to support your position, because it doesn't. A direct purchase (even at prices from 10 years ago) does not pay for itself in 5 years as you suggested. Recommending that somebody finance a direct timeshare purchase is financially irresponsible and just plain bad advice, no matter how happy it makes them. And being happy that you paid $90 in 2003 dollars direct vs. $75 in 2013 dollars resale makes no sense, financially speaking, as the former is clearly a worse deal than the latter.
That is certainly true. The counter argument is that one should buy based on what is, not out of fear of what may be. I'm all for insurance, and my life, home, business and car are all insured just in case of accidents or loss. But these insurances also carry a small premium relative to the benefit they would provide. Buying insurance for your timeshare and paying a 100% premium to me seems like folly.
The problem I have with posts like these that advocate buying direct and financing with utter disregard for the consequences is that the givers of said advice have no idea to whom they are speaking. Just because it works for them and they have a safety cushion does not mean that others are in that same position. Buying direct and paying double the cost of resale is a frivolous expenditure. It's not stupid, irresponsible or illogical. But it's frivolous. It's spending money that one doesn't have to. Financing that purchase can potentially be wasteful (in the sense of throwing money away) and, depending on one's financial situation, can be quite problematic. I feel that emboldening people who are thinking of taking this course of action without having all the facts is being irresponsible. I would much prefer people such as Best Dad Ever to qualify his statements by saying something like "it worked for me for xxx reason, but it might not work for you" as opposed to suggesting that it will work for everyone because he and his family members have done it. With all due respect, he is in year one of his ownership and that contract that he owes $100+ per point on is only worth $65 on the resale market should he need to get out of that loan. Explain to me again how this is a good thing?
