The best investment opportunities in Europe's real estate markets can be found in self-storage, says Frank Haggerty, portfolio manager with Duff & Phelps Investment Management. Other areas of growth are in the Nordic countries and in the German residential sector. REITs, however, have not been the growth driver many in the industry had hoped, he said. "We have seen the adoption of the REIT structure in the U.K. and Germany in the last number of years. It has not necessarily created the capital formation that many would have expected."
