If the economic downturn has pummeled home prices in many parts of the state, it’s nearly pulverized prices in some of the Bay State’s most popular vacation spots.

 Median selling prices for the state’s top 10 vacation towns – from charming Wellfleet on the Cape to picturesque Stockbridge in the Berkshires, shrunk 26 percent in the first half of 2009 compared to a year earlier. Statewide, the single-family median home price has only declined by about 13 percent during the same period, The Warren Group reported last month.

 Wellfleet’s median home price escalated to $780,000 in the first two quarters of 2004. This year, it plunged to $442,000 – a 43 percent decline. In nearby Orleans, the median home price tumbled to $468,000, down 26 percent from 2005.

 Stockbridge’s median home price, $357,500, is now down to about the same level it was five years earlier. A year ago at the same time it was $550,000.

 Of the homeowners in those 10 vacation communities, Becket property owners appear to have made out better. The median home price in Becket, a small community in the Berkshires that has plenty of summer camps, reached $257,500 in the first six months of 2009, up 5 percent from the same months in 2008 and a 75 percent jump from 2004.

 Keep in mind, however, that home sales in Becket sank from a high of 50 during the first two quarters in 2004 to just 19 this year.
