In Berlin, where settled refugees are expected to boost the urban population by 4.7 percent, property prices are expected to soar 14.5 percent by 2030. Without the refugee influx, prices would rise 8.5 percent during that period, Postbank explained by email.
Meanwhile, Potsdam is expected to see the second largest rise in population rates at 4.5 percent and Hamburg at 4.4 percent, the report stated.
The rise in refugee numbers itself won't directly affect real estate costs, but will cause a domino effect on prices, the report explains. Demand will rise for subsidized housing, which will in turn drive up demand and costs for higher end rentals and ultimately drive up purchasing prices.
Berlin is already suffering from reduced housing stock, according to reports. German newspaper Frankfurter Allgemeine Zeitung reported in February that Berlin's senate was negotiating a 600 million euro ($664.73 million) contract with the Grand City Hotels Group hotel chain in an effort to find a housing solution for 10,000 refugees.
However, that plan has been attacked by those who claimed the money should be used to house Berlin's homeless population rather than non-nationals.
