OK, so when we bought in 2013, we were in a position where we could afford the payments and didn't think we'd have issues down the road. Without getting into too much detail but for various health and home related reasons our situation has changed and we just can't afford the payments anymore so we are thinking of selling.
I don't know if anyone has mentioned this but one of the first things you need to consider is the resale value of your points vs. how much you still owe. Value varies greatly depending upon resort. If you look at the resale brokers' websites, their listings will give you a ballpark idea of what people are willing to pay.
The comment about "affording the payments" suggests that you took out a mortgage thru DVC. That mortgage needs to be settled before any transfer of ownership may occur. In other words, if you still owe $10k and agree to sell for $9k, you'll have to write a check for $1000 at closing to complete the transaction. Broker commission also needs to be factored-in.
If you've been paying down on the principle since 2013, you may be OK. But again, it depends upon many factors like the Home resort, size of initial down payment, if you've made extra principle payments, etc. Smaller, more sought-after resorts fetch higher sale prices than others.
Good luck.
