Another thing to keep in mind is with the recent increase in ROFR activity (now apparently subsiding), you may wish to ask the seller to pay all the fees, and in return, you will pay a higher $/point cost.
This *shouldn't* make a difference to Disney's ROFR decision, and yet close examination of Beca's ROFR thread suggests that there might be benefit to offering higher $/point + not paying MF / closing / etc, as compared to lower $/point, buyer pays MF + closing.
If you go this route, remember that commission is usually percentage of the contract amount NOT including MF/closing, so seller may need to ask the reseller to reduce the commission commensurately.
YMMV.
