We BOTH agree that SSR probably represents the best bang for the buck in terms of someone buying into
DVC that is flexible in terms of where they want to stay at the 7 month window.
But some people may consider VB over SSR in the following scenario.
Buy points at SSR @ $85 vs buy points at VB @$45
The difference between the two (assuming they are equal in terms of banked/current/future year points) is $40pp and probably a little higher in terms of closing costs, but lets just assume they are the same.
100 points = $4,000 savings buying VB over SSR
200 points = $8,000 savings buying VB over SSR
300 points = $12,000 savings buying VB over SSR
If SSR dues is $5.18 and VB dues is $8.06, then the difference is $2.88 per year
$40 / $2.88 = 14 years to catch up (assuming the dues will always be $2.88 more at VB) where it would be better to buy SSR over VB.
This also assumes both deals are paid in full for cash.
For some people that may only want to be a DVC member for 7-10 years then buying VB is possibly better than SSR, especially if they need 250 points as this would be a $10,000 savings. If they sell in 7-10 years, then the RTU really is not a factor and resale values will probably still have VB as the cheapest DVC and if the current price from DVC is $200+, then logically you could easily find someone to buy your VB for $40pp. Of course, perhaps SSR will increase in value while VB does not, but no matter what, buying VB NOW can save a lot of money if you plan is to only be a member for 7-10 years.
The average persona moves homes every 7-10 years so I would assume that there are many families that would consider buying DVC now and selling in 7-10 years.
