The CMA (comparative market analysis) is a good way to find out the real value of a timeshare. A lot of timeshare companies do that. I'm not sure if TSA does that or not. May be a TSA staff member can answer that for you.

But I've got to tell you - CMA is not the only way to find out your timeshare's worth. You can easily find out the real value of your timeshare by taking a quick look at the timeshare market. You can easily find out the average asking price for timeshares similar to yours. Depending on the location, season, and the size of the unit, you can fix the asking price. So, I would have to say that it is not that big a deal as it looks like. All it takes is a little effort on your part.

PS: Shouldn't this thread be in the 'Sell Timeshares' section?
