IMHO, it was the seller paying 1/2 MF's that made your package more attractive. Disney could care less about a contract being stripped, as there are so many members that dont manage their points and lose them and
DVC can make any contract whole, by using these lost points. Anytime the seller is willing to cover costs, that's just bringing DVC's cost to purchase that contract lower.
So when a Seller pays MF's that brings DVC's cost down to ROFR the contract. I would take all the costs into consideration and total the cost per point to know the true value of your next package.
With your new offer of $72, even with you paying closing, your total cost per point is $72. So the 1/2 MF's are equivalent to the seller paying your closing thru the eyes of DVC. That puts your point spread at $18 ppt (from $89) Most get by with a $10 to $15 point spread.
Whichever you choose, SSR is definitely not a bad choice. If you take the $10 incentive, you will receive 05 points and as TJ says you will not pay MF's, interest or payments until your your building opens. Also the $10 incentive is credited to your 20% down payment so you would only have to put 10% down.
I purchased phase II SSR and my payments/interest won't be due until May 2005.
