Pricing your unit
If you want to sell your unit you need to price it realistically. Like cars timeshares depreciate.
Off season weeks have limited value and are hard to sell, I routinely sell them at my auctions for $1, At this time we do not accept any listings for off season weeks.
Fringe Season weeks (spring or fall) are, in my opinion the best value, but they are also not worth a great deal of money, if the sale price covers all your closing costs and puts a few hundred dollars in your pocket, you are doing pretty well.
Prime Summer weeks, can demand value, depending on the resort they usually sell for between $750 and $4000.
Who pays what
The buyer usually pays the closing costs
Whoever gets use of the unit usually pays that years maintenance fees
