Administrative muscle, not deal flow, is driving German fund growth

German real estate funds enjoyed expansion in 2025, but the driver was not a surge in property buying. Fund vehicles are increasing while transaction volumes stay muted. Portfolios are being shifted into professionally administered fund wrappers, reflecting a market that is scaling its structures faster than its deals.

INTREAL, Germany’s largest independent service KVG, embodies the shift. Its €72.7bn in assets under administration as of 30 September 2025 represents 9.2% growth since year-end 2024, accelerating from 5.8% in the first half. The firm now administers 341 funds and 2,888 properties, adding 154 assets since the end of 2024. The key signal sits in the mix: KVG services grew by roughly €4bn in one quarter to €36.1bn, approaching half of INTREAL’s total AuA. The growth is fuelled by the work investors increasingly outsource — reporting, accounting and regulatory duties — not by transactions themselves.

CEO Camille Dufieux summarised the mood in December: “Investors are once again looking at new product ideas.” The more telling behaviour is what happens next: investors are reviewing assets they already own and placing them into administered fund vehicles that can handle regulation cleanly and consistently ahead of 2026 vintages.

ESG myths meet German fund evidence

A second current in 2025 comes from research that punctures two assumptions about German fund allocation. The first belief holds that Article 8 ESG funds trade returns for sustainability. The second treats market location as the main source of outperformance.

Studies by Reax Advisory (part of INTREAL) and RheinMain University of Applied Sciences, examining 2017 to 2024, found no lasting return gap between Article 8 ESG funds and conventional Article 6 peers. Reax MD Annika Dylong summarised the headline conclusion: “There is no economic reason to avoid funds with ESG characteristics.” The warning that matters more is this: ESG labels are not always reliable. Some managers deliberately choose lower classifications to avoid heavier disclosure or liability risk. ESG integration, the data suggests, does not reduce returns. Over-claiming ESG sometimes does.

On location, Professor Leo Cremer distilled the second takeaway: returns are shaped not just by the city, but by the manager and the way portfolios are built and balanced. Strong teams have delivered extra returns year after year through asset selection and portfolio design, even in cities that do not top the rankings.

The wrapper is becoming the infrastructure

INTREAL’s growth supports the belief-reset now occurring in capital behaviour. Investors are placing greater weight on the fund wrapper and the teams operating it. Luxembourg structuring, paired with German KVG administration, has become a standard route for cross-border capital seeking regulated exposure to German assets without wrestling every regulatory detail in-house.

The ecosystem is expanding where administrative control is strongest: in regulated vehicles holding existing assets, rather than in new land banks or speculative development. The German transaction market remains subdued, but the migration of assets into administered fund structures is vigorous — aligning with evidence that execution, selection and structure all shape returns independently.

Implications for the real estate sector follow logically. Administrative capacity is becoming a crucial part of investable infrastructure. More funds are being created to hold existing assets, fewer to build new ones. Managers that combine realistic ESG claims with clear structures and capable teams will be best placed to absorb international capital in 2026. The sector is shifting into a phase where the investability of German property increasingly depends on the quality of the fund wrapper around it — and the competence of those who run the wrapper.
