Average prices in these towns have soared by 97 per cent over the past 10 years, a bigger rise than the typical 95 per cent increase seen across England and Wales, Halifax said.
Since 2002, prices have more than doubled in around half of seaside towns in England and Wales, according to the findings.
Seaham, in County Durham, with its dramatic clifftop coastline, saw the biggest jump, with a 183 per cent increase taking typical house prices to nearly £109,000 by 2012.
