If you decide to use your banked HGVC points, see this thread about what happens to existing reservations when your HGVC week is sold - "What happens to HGVC res and RCI res when ts sold (2015) -

Most buyers are going to want to travel in the year of their purchase. So having 2016 points available to a potential buyer makes your offer more attractive. Pay your Maintenance Fee and require a reimbursement of the fee for the unused points.
For resales in general....
It's easy to buy but harder to sell.
There are more sellers than buyers.
The higher the price the longer it's going to take to sell.
Some timeshares are on the market for weeks, months, years and some never get sold (due to various reasons over priced, over supply, low demand, etc).
NOTE: ROFR impacts the buyer (not the seller). In either scenario, the seller still gets rid of their week.
If I were you and really wanted to sell, my goal would be to get rid of it before fees are due next year. Because each year as HGVC fees increase, the potential market of buyers will decrease (simply because they can't afford it - it becomes too expensive for some).
Keep in mind that the buyer typically pays the selling prices, reimbursement for maintenance fee (if points are still available), closing cost (approx $100 - $500 depending on the company used) and HGVC transfer/enrollment fees which have been steadily increasing (approx $1000).
