Between Statistics and Reality: The Berlin Portfolio Market

However, this interpretation falls short. In fact, 2025 was the first year since the interest rate turnaround in which a significant number of larger residential portfolios were actively on the market again. In total, more than a dozen portfolios were on the market over the course of the year—with volumes that correspond to the typical target sizes of institutional investors.

Demand was correspondingly high

Many of these transactions saw unusually broad investor participation. In some cases, several dozen indicative offers were received. What stood out was the wide range of asking prices. There were often significant differences between the highest and lowest bids.

This range reflects a market in which valuations are once again being scrutinized more closely and which is recalibrating itself overall.

Investors are conducting due diligence much more intensively today than they did just a few years ago. Capex requirements, energy efficiency, tenancy law risks, and potential for redensification are analyzed in great detail. Often, multiple technical consultants support the due diligence processes simultaneously. Equity partners are also becoming more involved than before and scrutinizing business plans more critically.

In several cases, it was precisely this in-depth scrutiny that led to transactions being halted in the late stages. The result: Many processes were initiated in 2025 but were not finalized in the same year.

Some of these portfolios are now being restructured, in some cases split into partial sales or individual transactions. Others remain in advanced negotiations and are expected to be finalized in the course of the first half of 2026.

The key observation is therefore:

The portfolio market is already significantly more active than the published transaction figures suggest.

Those who look exclusively at the volume of deals closed currently see only the tip of the iceberg. Beneath the surface, numerous processes are underway that show institutional capital is once again actively seeking larger investment opportunities.

Discussions at MIPIM in Cannes last week also reinforced this impression. Berlin is back on the agenda for international investors—albeit under changed circumstances. Interest has become more selective, due diligence processes more thorough, and yield requirements more clearly defined.

This new discipline in particular is an indication that the market is stabilizing.

The Berlin residential investment market is thus entering a phase in which not every project will be financed, but rather solidly structured transactions with a clear outlook.

For the portfolio market, this means: The foundation for a noticeable revival has already been laid. It is likely to become visible above all in the coming months—specifically when some of the processes initiated in 2025 actually materialize in transaction volume.
