The estate agent produced a map to illustrate the change in prices, which shows that house prices in more than 74% of the countries competing in The Euros have risen in the last four years.
House prices in Turkey rose the most, up by 65.6% since 2012, followed by the Republic of Ireland where they were up 34.3% since 2012 and Iceland where they increased by 30.6%.
Prices fell in six of the 23 countries taking part in the championship and dropped the most significantly in the Ukraine, where they are down by 22.6% since 2012.
The host, France is favourite to win the competition but house prices are 6% lower there now than they were during the last championship. However, Knight Frank said the country’s poor performance had bottomed out with growth of 0.5% recorded in the last 12 months.
