Impact investing in real estate has to clear two hurdles at once: projects must be financially viable and deliver measurable social value. Real estate projects unfold over long timelines, involve diverse user groups and depend on complex local partnerships. That makes rigorous impact measurement essential to credibility. Without a clear structure, it’s often impossible to tell whether a project is genuinely addressing a social challenge or simply telling a good story.

That’s where the IMMPACT Guide comes in. Developed by the Bertelsmann Stiftung together with SEND, the German Association for Impact Investing and PHINEO, it provides a clear, shared point of reference. Its structured set of guiding questions – from needs assessment and impact hypotheses to KPI design – makes impact easier to understand, compare and communicate. For real estate in particular, the framework provides the methodological clarity the sector often lacks. Even more importantly, it makes getting started simple. All stakeholders can move straight into action without first having to navigate complex theoretical impact models. The result is a much lower barrier to entering the impact market, a common foundation for impact-driven collaboration, and a strong basis for critically reassessing existing business models.
Advancing the IMMPACT Guide for real estate
To reflect the realities of the real estate sector, we have refined the approach further within the Real Estate Working Group of the German Association for Impact Investing and adapted it to real transaction processes. The result is a practical guidance note with an investment checklist. Building on the IMMPACT Guide, it gives practitioners a clear, robust structure they can apply right away. The need is clear: many project developers have strong ideas or available sites, but lack a proven method to plan, measure and communicate impact in a structured way. Together, the IMMPACT Guide and the practical guidance note offer a low-threshold entry into impact investing. They help actors move faster and support a rapidly growing ecosystem of committed impact players.
At NEXT Generation Invest, this logic is built into our Impact Management and Measurement approach. We start with needs assessments and a clear theory of change, define impact goals and translate them into actionable KPIs. Standardized due-diligence tools, regular impact performance reviews and clear collaboration processes with partners ensure consistency and accountability.
Case in point: Frankfurt Hausen
What this approach looks like in practice is illustrated by the Frankfurt Hausen project. Originally designed as socially oriented housing, the property faced major challenges before its acquisition by NEXT GI: high rents, limited interaction between resident groups and growing resistance within the neighborhood. Using the IMMPACT guiding questions, the first step was a clear needs assessment at the site. The result: demand for affordable housing for students, people with special housing needs and – intensified by the war in Ukraine – refugees. These needs were translated into a clear theory of change with three concrete impact goals:
- Increase affordability, including an average rent reduction of around 20% for student apartments.
- Strengthen social integration, through redesigned shared spaces and a rental model that actively encourages voluntary engagement.
- Activate local ecosystems, by involving community-oriented organizations and municipal institutions.
Impact is tracked through clearly defined KPIs, including rent relief, quality of social interaction, occupancy structure and regular feedback from key stakeholders.
The Frankfurt Hausen example shows that impact doesn’t happen by chance. It is the result of deliberate, structured impact strategies. The IMMPACT Guide and the practical guidance built on it provide exactly that orientation – helping establish a shared understanding of impact across the real estate sector. Credible impact measurement requires both a clear methodological framework and a willingness to work in close partnership with local actors.
