Using historical data from the MLS, property values increased from 2001 to 2006 by 7-9% (Sales History) but from 2007 to 2008 ther has be a decrease by 3-6% (Sales History). Water property for the most part is different because people will pay more than market value sometimes if that is a property they truly love ( Flat, Great views, Sea walls ) and is special in some way to them. Water property is in most cases a 2nd home for summer fun with the family and in most cases will pay more than market value to obtain that special property for the family. As each property is different, the above statements will vary and to help find a market value of a property located on the water, have a Realtor comp the property as to current market values to get a true picture of a property's value. - Fri Sep 5 2008, 14:01
