The key word is if you can AND do pay it off, the reality is that most don't and sometimes things happen that they can't. Brian my view is there is no good consumer debt. I also believe that debt is mostly about behavior and very little about math. It represents risk, plain and simple. I'm not against playing games with such issues, financed a timeshare one time I was going to buy anyway to get the incentives then paid it off in a month. I realize there are degrees of risk here but for most, financing represents buying something they couldn't afford. One who choses to finance but doesn't have to is taking far less risk but they are still taking risk and are in the minority. But the reality for something like
DVC isn't the person who has plenty of money and decides to finance usually they have significant other debt like cars, HELOC, credit cards, student loans, etc. I firmly believe that if one wants to own DVC they can save up and buy within 2 years and if they can't it's either something they can't afford or not really important to them or both. Just do a search for net worth or retirement savings to see ow bad it is.
