Office Market Cologne — Figures Compared by Source

What 12 research houses currently report on the office market in Cologne — rents, yields, vacancy and investment volume side by side, rather than scattered across separate reports. Where the figures disagree it is usually a matter of differing definitions, so they are shown per source and never averaged. Rent, yield and vacancy figures cover Q2–Q3 2026, plus full-year and forward-looking figures where sources publish them; older figures are not shown.
