If your financial person is telling you it will be almost impossible to sell your DVC points, then he/she doesn't know much about the DVC.
It shouldn't be terribly hard. List them with a reputable broker (we bought from Pat Spell at The Timeshare Store and had a great experience) and if it's priced properly, it should sell quickly.
Think long and hard about this. Points are going up every day, and while you will be able to purchase them back someday, it'll be a lot more expensive then.
