Overview
- Late August 2026 regional releases of BBSR/IDN data confirm that average offered net cold rents rose markedly from 2010 to 2025 and that growth accelerated in the 2015–2025 period.
- The analysis covers advertised, unfurnished apartments of 30–130 m² and reports county averages and annual growth rates rather than signed contract rents.
- County extremes in 2025 are large: Landkreis Harburg showed the highest average offered rent at €12.31 per m² while the city of Salzgitter recorded the lowest at €6.49 per m².
- Local reporting in the Augsburg area, using ImmobilienScout24 figures, finds rents climbed almost 20% since 2022 and warns those increases are rising faster than local wages, producing waiting lists for subsidized housing.
- The listings‑based picture points to uneven local markets where proximity to cities, housing stock and new‑build shares shape prices, and where rising advertised rents could push policy debate on landlord practices, more affordable supply and targeted housing support.
