By Kate Holton LONDON (Reuters) – Britain’s second-largest property website Zoopla plans to list its shares on the London stock market next month to tap into rising confidence in the country’s housing sector, potentially valuing the group at about 1 billion pounds ($1.7 billion). Majority owner Daily Mail & General Trust (DMGT) said Zoopla’s existing owners planned to sell shares in June to institutional investors and the estate agents who pay to list properties on its websites. Zoopla, which was launched in 2008, trails Rightmove in the online property sector, drawing more than 40 million visits a month to its websites and mobile applications, compared with about 80 million visits for its larger rival. It joins a rush of companies seeking to join the London market and follows recent listings by online groups AO World and Just Eat and property agent Foxtons last year.
