Overview of the Research Paper
The study “Financialisation and Rental Housing: A Case Study of Berlin” is a working paper (No. 153/2021) authored by Clementine Davies and published by the Institute for International Political Economy Berlin (IPE Berlin). IPE Berlin is a research institute focusing on political economy and urban issues. The paper, edited by a team of scholars including Sigrid Betzelt and Eckhard Hein, was released in 2021 and investigates how financial motives have reshaped Berlin’s rental housing market.
Context and Motivation
Berlin’s housing market has undergone rapid change since reunification, with large‑scale privatization of former public stock and a surge in private equity investment. Rents have doubled in some districts, vacancy rates fell to 0.9 %, and the city now has 85 % renters. The research aims to quantify the extent of financialisation—defined as the growing role of finance in corporate strategy—among five major publicly listed rental housing firms operating in Berlin.
Methodology and Data Sources
The author analyses annual financial reports from 2008‑2018 for Deutsche Wohnen, Vonovia, ADO Properties, TAG Immobilien, and Grand City Properties. Indicators include financial income and expenses as percentages of profit, revenue composition (rental vs. sales), dividend payouts, maintenance versus modernisation costs, and balance‑sheet ratios (equity, loan‑to‑value). Comparative data from the municipal housing provider Gewobag are also presented.
Key Financial Findings
- Financial income as a share of profit declined across all firms, indicating limited reliance on pure financial earnings.
- Financial expenses also fell, except for GCP (which rose) and TAG (which spiked due to bond issuance).
- Sales income grew for Vonovia and Deutsche Wohnen, while the other firms remained stable or fell, suggesting modest short‑term profit seeking.
- Dividend payouts consumed 44 %–64 % of earnings‑before‑interest‑and‑taxes (FFO), highlighting strong shareholder orientation.
- Equity ratios increased for most firms, while loan‑to‑value ratios decreased, showing no substantial debt‑leveraging trend.
- New construction represents only 4 %–5 % of rental income for the private firms, contrasted with a 38 % investment rate by Gewobag.
Impact on Housing Supply and Quality
The five private firms together own roughly 11 % of Berlin’s rental stock, yet their investment in new construction is minimal. Modernisation costs rose sharply (e.g., Deutsche Wohnen’s modernisation expense rose 611 % to €30.91 / m²), which correlates with higher in‑place rents. Limited new supply combined with rent‑price increases (average rent growth 33.5 % for Deutsche Wohnen, 25.9 % for Vonovia) exacerbates affordability challenges, especially for low‑income households.
Social and Policy Implications
Tenant protections remain robust (long‑term leases, rent caps, rent‑price brake), but the profit‑driven strategies of private landlords pressure rents upward. The author suggests that sustainable housing outcomes will require stronger public investment, incentives for non‑profit housing providers, and policies limiting speculative sales and foreign ownership. Recommendations include higher land‑transfer taxes on resale, empty‑house taxes, and prioritising municipal access to affordable land.
Conclusions and Future Directions
The paper concludes that while Berlin’s rental firms do not increasingly depend on financial instruments, they exhibit pronounced shareholder focus and short‑term incentives. Their limited contribution to new construction leaves the burden of expanding affordable housing on the public sector. Further research is proposed on the social effects of modernisation, comparative analyses with cooperative housing models, and the long‑term environmental sustainability of Berlin’s housing stock.
