Transactions in Germany's giant yet troubled property market rose slightly in the first nine months of the year, data from JLL showed on Monday, as the global property firm and industry leaders cautioned that a rebound in Europe's largest economy will be slow. Turnover of investment properties from January through September stood at 23.4 billion euros ($25.66 billion), a 5 per cent increase from the previous year in a sign of a bottoming out after a two-year market implosion as the nation went through its worst real-estate crisis in decades. Falls in prices of commercial and residential property have begun to taper off, with central bank interest rate cuts in both Europe and the United States helping to stabilise the situation, JLL said.
