Millions of German tenants have to adjust to rising housing costs: Germany's largest real estate company, the Dax group Vonovia, considers significant rent increases to be inevitable in view of the high inflation rates.

"If inflation is permanently at four percent, rents will have to increase accordingly every year in the future," said Vonovia CEO Rolf Buch to the "Handelsblatt".

Otherwise, many landlords would get into serious trouble.

“We can't pretend that inflation is bypassing rents.

That won't work," Buch continued.

The real estate giant owns around 565,000 apartments, most of them in Germany.

The average rent demanded by Vonovia increased to EUR 7.40 per square meter in the first three months of this year – that was 3.1 percent more than a year earlier.

This is still well below the current inflation rate of just under eight percent.
