German home price growth is slowing, signalling a cooling housing market amid tight affordable supply
Executive summary: German residential property prices continued to rise in September 2026, but the rate of increase slowed, with apartments in hot markets even dipping slightly lower; affordable housing remains scarce. The slowdown signals a cooling housing market that could impact construction, mortgage lending, household wealth, and affordability policy debates.
Who is involved: Homebuyers, sellers, real estate agents, German construction industry, mortgage lenders, federal and regional housing policymakers.
Likely next: Continued monitoring of quarterly price indices; possible policy responses to increase affordable supply; potential influence on interest‑rate outlook if inflation eases.
German residential property prices rose in September 2026 but the pace of increase weakened, with apartments in high‑demand cities even edging slightly lower. The cooling reflects weakening demand amid persistent supply constraints, leaving affordable housing scarce. This suggests the earlier rapid price acceleration of 2023‑2025 is losing momentum, which could affect construction activity and mortgage lending. Policymakers may face renewed pressure to boost housing supply to preserve affordability.
