No, there are times when financing is a good idea. But the worst case is far from "we will take a lot of trips then sell for a couple thousand less than we bought it for."
Part of the reason some of us are pretty adamant on the whole "bad idea" is that for the FEW people for whom its a good idea, they tend to know who they are. For each one of those, there are probably ten people who read the
DVC purchasing board exploring the idea of buying DVC for whom it is not a good idea and are not financially savvy. If even one of those ends up in a less secure financial position because of something I posted, I'd feel like I did them a disservice.
And it isn't just that - when people get themselves into bankruptcy situations, or foreclosure situations - that effects all of us. Its a drag on the economy. It increases costs for the rest of us - or, in the case of DVC, can lead to depressing the costs on the resale market - where I plan on selling my DVC. I suppose if you are in a position where you want to buy points, you could cheer on people, hoping there would be a lot of distressed contracts hitting the market.
Even short of bankruptcy situations, if you spend today and don't have money to help your kids with college or for your retirement, society as a whole suffers.
