I think there are a couple of factors at play, the most important, long term - @ least until end date of contract comes into play - being the number of units at the resort which is all about supply and demand:
SSR - 828/1260 villas average listing $96 range $82/104 end date 2054
OKW- 531/761 villas average listing $85 range $70/120 end dates 2042/2057
AKV - 458/708 villas average listing $101 range $90/116 end date 2057
BWV- 383/532 villas average listing $106 range $95/127 end date 2042
BLT - 295/428 villas average listing $134 range $111/150 end date 2060
Poly- 380 villas average listing $146 range $135/155 end date 2066
RRV - proposed 300 villas
BCV - 208/282 villas average listing $122 range $115/128 end date 2042
CCV - 184/220 end date 2068
BRV - 136/181 villas average listing $85 range $81/95 end date 2042
VGF - 100/147 villas average listing $143 range $119//160 end date 2064
These prices are from a site that collects data from several but not all brokers. The larger villa numbers reflect maximum no. of villas (e.g. when 2 br. lock off used as studio + 1br.)
My personal gut feeling when I bought AKV a couple of years ago was that it was under priced compared to SSR & BLT, most likely because of the higher MFs at AKV & that through time SSR's & BLT's MFs would rise faster than AKV's & that ultimately the MF's would equalize w/ AKV's always being slightly higher, that BLT would always resell for more due to fewer villas & a more desirable location, but SSR should resell for less than AKV ultimately because it was so much larger, thus would always have more supply.
