Rents Rise 4% Across Germany in Q2 2026, with Cologne Leading at 7.9%
German rental offering prices jumped 4% year-on-year in the second quarter of 2026, driven by constrained supply and shifting tenant behavior. Major regional variation emerged, with Cologne recording the sharpest increase at 7.9%, while Berlin showed resilience at just 1% growth.
German rental markets recorded sustained upward pressure in the second quarter of 2026, according to latest data from the Institute of the German Economy (IW Köln). The nationwide average asking rent reached 4% year-on-year growth, reflecting a structural imbalance between tight housing supply and persistent tenant demand.
Regional Divergence
The growth trajectory varies significantly across major cities. Cologne led with the steepest climb at 7.9% annually, while Hamburg reported 5.5% growth. Berlin's rental market continued its stabilization pattern from earlier quarters, with offering rents rising only 1% — a marked contrast to the sharp increases seen in 2023 and 2024. Stuttgart showed the most modest growth at 0.9%.
The rental supply itself contracted by approximately 12% since early 2022, with Hamburg's available listings halving over that period. This scarcity, combined with tenant reluctance to move and the structural shortage of 600,000 units nationally, sustains upward pressure on rents.
For renters signing new leases, the Mietpreisbremse (rent brake) continues to provide a legal ceiling in designated tight housing markets — capping new rents at 10% above the local reference rent (Mietspiegel). As an expat or new resident, verify whether your target city has this protection in force and check the current local Mietspiegel before agreeing to any rent. If your new contract exceeds the legal limit and no exemption applies, you can claim reimbursement for up to 30 months of overcharged rent.
