Turkey is one of the most attractive markets for global real estate funds, but the lack of investment grade retail assets remains a major concern to retail investors, according to DTZ. In its Turkish retail market overview for 2007, the global property adviser notes that the number and value of retail centre transactions accelerated considerably last year to a record EUR 800m. Volumes are lower this year, however, with a total of EUR 338 mln in deals recorded up to October.
