The Trulia list of homes for sale in Dillon Beach shows asking prices, that should help. You can also get a list of recently sold in Dillon Beach and sort that return by "newest". This gives you a pretty good idea of recent activity.
The link below will provide more analysis.
We all know the economy is low and previous expections are gone. But if you need to sell...well we look at the comps, features and condition of property and then take it from there. However spring is the best market. Listing a beach house towards winter is not usually recomended. If you can hold until spring...I would freshen it this winter, fix any issues and be prepared to come on the market in March.
