First, hugs and pixie dust as you adjust to your new reality...may good times return soon.
Depending on how much you paid, and how big your loan balance is, you may find that selling is not your best option, financially...you may do better renting your points (or transferring them)...
Of course, it all depends on your specific numbers...monthly payment plus dues is one number. About $10/point rented is the other number. If the rental number is bigger than the payment + dues number, that's probably the way to go.
We bought our points in 2006-2007, at an average cost of about $90/point (we paid more for our BCV points, less for our SSR points)...those points are selling these days for around $50 (give or take)/point...we didn't finance, so no real idea of what the loan balance would be after 4-5 years...but assume 50%...then add in sales costs (at least commissions and possibly closing costs, depending on what you negotiate w/a buyer)...
It all comes down to your individual math.
GOOD luck and hope you find a way to get back to
DVC affordability as soon as possible...
