German outpatient healthcare is gaining ground — but scale remains elusive

Germany's market for outpatient healthcare properties recorded transaction volume of around €200m in 2025 — more than double the €91m recorded the previous year. Set against an overall commercial property market that shrank by 5% year-on-year, the 120% growth in this segment is striking. The broader care and healthcare property market reached €1.2bn, up 23% on 2023, with CBRE forecasting outpatient volume alone exceeding €300m in 2026. Prime yields have held stable at around 4.6% since 2024.

These are still small numbers. But the direction of travel is harder to ignore. What is emerging is not simply a faster-growing niche, but a segment that is beginning to take on the characteristics of a distinct asset class — one that institutional capital can increasingly understand, underwrite and, crucially, scale.

The forces behind that shift are structural rather than cyclical. Hospital reform legislation, now passed by the Bundestag, has embedded the principle of "outpatient before inpatient" as the organising logic of German healthcare policy. Around 97% of all treatment cases already occur in the outpatient sector, yet the inpatient system continues to absorb a disproportionate share of statutory health insurance (GKV) expenditure. Correcting that imbalance is an explicit policy objective — and one that requires physical infrastructure. A €50bn transformation fund, approved alongside the reform, will support the restructuring of hospital sites, some of which may be converted into cross-sector outpatient facilities. Demographics reinforce the trend: an ageing population is increasing demand for accessible, decentralised healthcare provision in both urban and rural settings.

What investors are responding to is not only demand, but the quality of income. Outpatient healthcare properties offer a combination that is increasingly rare in other segments. Leases are largely index-linked, providing inflation protection. Tenant structures are granular and stable, with medical practices, pharmacies and therapy providers benefiting from predictable revenues within the statutory system. Default probabilities are correspondingly low: general practitioners and medical care centres average just 0.26%, with similarly low levels across other outpatient uses — well below inpatient facilities, where care homes average 1.17% and hospitals 1.52%. "The data confirms the generally high stability of outpatient healthcare properties, including in terms of tenant creditworthiness," says Felix Rotaru, Director of Healthcare at Hauck Aufhäuser Lampe Real Estate Investment Management (HAL REM).

From stable income to a shortage of scale

Transactions remain dominated by individual deals, typically below €50m, although the first portfolio transactions have begun to emerge. On the buyer side, international institutional investors — including open-ended funds, specialist funds and private capital — are becoming more visible, attracted by stable cash flows, lower operational risk and a segment that is still in the early stages of institutionalisation.

Geographically, the market diverges from familiar patterns. Of the approximately €2.1bn invested since 2016, around two-thirds has been deployed outside Germany's seven largest cities. B, C and D-tier locations are central to the investment case, reflecting both the distribution of healthcare infrastructure and the relative scarcity of suitable assets in prime markets. An updated analysis by Rebmann Research in cooperation with Hauck Aufhäuser Lampe identifies 4,336 outpatient healthcare properties nationwide, with particularly high concentrations in eastern German states and city-states such as Hamburg and Berlin.

This is where the central contradiction of the market becomes visible. Based on average purchase prices, HAL REIM derives a potential market volume exceeding €37bn. Yet annual transaction activity remains a fraction of that figure. The gap is not one of demand, but of structure. The market is fragmented, lot sizes are small, and investable portfolios remain scarce. For institutional investors, the challenge is not identifying the opportunity, but accessing it at scale.

Signs of consolidation are beginning to appear. Larger portfolios are attracting international capital precisely because they offer what the market otherwise lacks: scale and portfolio depth. Broader developments in the healthcare property sector, including ongoing consolidation among listed operators, underline the growing importance of size for institutional investors.

For now, however, outpatient healthcare property remains an emerging institutional market. The investment case is clear: structural demand, policy support, index-linked income and comparatively low tenant risk. But its next phase will be defined less by those fundamentals than by the industry's ability to create, modernise and assemble sufficient stock to meet institutional demand. As Patrick Brinker of Hauck Aufhäuser Lampe puts it, there remains "significant development potential, particularly in medium-sized towns and rural regions". For investors, that potential is not a side note. It is the core of the opportunity — and the constraint that will shape how far and how fast this segment can grow.
