Some 600 million of Irish capital could be invested in the German capital over the next two years, according to investment fund managers. Residential properties in Berlin in particular are considered undervalued and the commercial property market is also attracting interest. Companies such as BDO Simpson Xavier, Merrion Capital, Elgin Capital, Harvest Financial Services and Tiger Developments are all looking for opportunities on the Berlin property market. Only about 12 per cent of Berliners own their own properties, which makes the city a haven for investors in the buy-to-let market.
