Bear in mind that commission runs about 10% to the agent handling your resale.
If you can get $90 per point, you'll only clear about $12960 after commission ($90 x 160 x .90) Depending on how recently you purchased, the price paid and amount financed, the amount you recoup may not even cover your outstanding loan. If financed thru DVC, they will need to be made-whole when the contract changes ownership.
The full dues for 2009 will also need to be paid before closing, although you can negotiate with your buyer to fund that debt.
The amount of points available in the contract will go a long way toward determining how much you will get for it and how quickly it will sell. Assuming you are in your 2009 Use Year, if you have used some or all of the 2009 points and even borrowed against 2010, you're facing an uphill battle. With so many contracts on the market now, you'll have to discount your asking price in order to attract interest. But if you have all '09 points available and perhaps even some banked points from 2008, it will be a very appealing contract to potential buyers.
If the numbers don't work out in your favor, consider renting your points for a few years and hoping your situation improves. That may help you come close to covering your dues and monthly payments.
Good luck.
