Are you considering the remaining value of your contract? If you sell now, you can recover a good part of your initial investment making your vacations cost, even cheapier.
I'm evaluating purchasing DVC, and the remaining value of a contract after 10 years is almost the most important variable of all my projections.
I've seen than most people make their evaluations considering the full life of the contracts (until expiration, so remaining value = 0). I understand doing that, but if instead you do a 8, 10 or 15 years projection considering a final sale of your contract at an estimated remaining value, your results can be very different.
Even making that kind of projection, you can decide you want to keep your contract until expiration. But that decision hasnt to be made today, you can decide that anytime.
A timeframe of 8, 10 or 15 years is easier to foresee in terms of your family vacation requirements/plans. Most families can see they are wanting to go yearly/often when their kids are younger but are not sure what will happen after that. So, adding the remaining value of their contract at the "end" of that period makes a lot of sense when you are considering the purchase.
Yeah, it isn't a material amount of money for us, so I'm not worried about it.
