Rich is correct in that when comparing resale vs. Disney you MUST also compare points available, banked, borrowed or otherwise.
Example: Take for example an August use year, resale 150 point contract for $70/point plus $500 closing cost. Say this contract has all 2003 points available and 50 banked 2002 points available. Your cost is $11,000 ($70 x 150 + $500)
Disney offers you an August use year, magical beginnings for $74 / point. So your 150 points costs $11,100 or seemingly close to the resale deal.
But to make the
DVC deal equivalent to the resale, you go and rent 200 points somewhere so you have the equivalent points the resale gives you because of banked and current year points.
Point rentals go for about $10/point. So to make the DVC purchase equivalent to the resale purchase, your total cost is $13,100 ($11,100 + $2000).
I'm not sure about this last item, but with Disney MB, don't you still pay the maintenance fees on those points you give back? If so that reduces their value. If not then the value is the $10 / point they are offering. As to resales, paid maintenance fees are negotiable between buyer and seller, so that can make a difference one way or the other also.
The biggest difference in this example, in the resale you have 50 points to use right now, and will receive another 150 in August 2003. (for $11,000), while with Disney, you receive no points at all until August 2004 (for $11,100)
While MB can have it's advantages such as Disney financing, lower down payment or lower mortgage balance, it is not the same when comparing it's comparable 'value' to many resales. What they offer is equivalent to buying a resale where the owner had used all their 2002 points and had borrowed and used all their 2003 points, leaving nothing but the 2004 points available.
