Massanutten summer weeks (and week 52 and maybe 51) that have been converted to points is probably an easy giveaway and could probably net a few hundred if you are willing to wait 6-12 months in order to find someone willing to pay.
Summer weeks that haven't been converted to points you can probably find someone willing to take as a give away but if you want that person to pay for the transfer it could take 6-12 months. If you are willing to pay the transfer and give them the current summer usage, you probably could give it away in less than 6 months.
If you don't own a summer or New Years week, expect at minimum to pay the transfer and cost of the new deed and pay MF's and give free usage for the first year and you may have luck finding a new owner. Depending on the week, you may have to do that and prepay another year's MF's or offer a cash gift when the transfer is complete.
