A New Perspective on Rental Housing
Sustainable Build-to-Rent and Institutional Residential Developments
A new real estate market opportunity. Professional rental housing is not simply about long-term apartment leasing. It is an investment and operational model that prioritizes the full lifecycle of the building: energy and water consumption, resident comfort, durability, maintainability, and long-term asset value. For this reason, sustainability considerations carry business significance from the very first project decisions. |
Why Talk About Rental Housing Now?
In the Central European real estate market, professionally developed and operated rental housing—namely Build-to-Rent (BTR) and the institutional Private Rented Sector (PRS)—is becoming increasingly prominent. The core of this model is that an entire building or large residential portfolio remains under single ownership for the long term, shifting the focus away from individual apartment sales toward stable rental income, efficient operations, and long-term value creation.
In Hungary, a key catalyst is the recently announced Wekerle Sándor Housing Program by Dávid Vitézy, a central element of which is incentivizing institutional rental housing developments.
As consultants at Greenbors, we view this as a particularly compelling direction because a long-term ownership mindset naturally reinforces the business importance of sustainability. Energy efficiency, water conservation, indoor environmental quality, durable materials, measurability, and high operational data quality are not just environmental issues—they are directly relevant to OPEX, tenant satisfaction, bankability, and future asset value.
Hungary – A Highly Owner-Occupied Market with Few Institutional Alternatives
Compared to the European average, Hungary is a strongly homeownership-oriented market. According to Eurostat, 92% of the population lived in owner-occupied homes in 2024, whereas the EU average was 68%. Within the EU, only Slovakia, Romania, and Lithuania join Hungary above the 90% threshold. At the other extreme stands Germany, where more than 50% of the population lives in rented homes, closely followed by Austria, France, and Nordic countries. Southern European countries, Slovenia, and the Czech Republic lie in between with rental rates around 25%, while in other Eastern European nations, this figure remains below 20%.
The domestic rental market—still small by EU standards—is highly fragmented: a significant portion consists of individual private landlords, while the institutional BTR/PRS sector developed specifically for long-term leasing remains in an early stage.
Meanwhile, rental yields and prices have risen significantly. According to the KSH–ingatlan.com rent index, Budapest asking rents increased by 0.9% month-over-month and 5.2% year-over-year in August 2026. Compared to the 2021 baseline, nominal Budapest rents were 78% higher, representing a 20% increase in real terms.
Concurrently, home purchase prices rose even faster. According to the MNB (Central Bank of Hungary) Housing Market Report from May 2026, nationwide nominal home prices grew by 23.5% in 2025. By Q4 2025, prices were estimated to exceed levels justified by market fundamentals by 22.5%. Wages did not keep pace with this escalation, further worsening affordability. This environment significantly enhances the value of predictable, professional rental alternatives.
On the supply side: in Q1 2026, approximately 22,000 residential units were under development and sale in Budapest—a 46% year-over-year growth and a ten-year peak. Over the medium term, this expands room for structures where an entire building or project block is retained under single institutional ownership rather than sold piecemeal.
Our takeaway: The Hungarian market currently operates between two main poles: buying a home or renting from a private individual. Professional rental housing introduces a third path: institutional, predictable living where sustainability and technical performance are built into the product. |
Austria – Rental Housing as a Core Pillar
Austria is the antithesis of the Hungarian model. In 2024, 46% of the population rented, marking the second-highest rate in the EU after Germany. In Vienna, OECD data shows that around 80% of housing is rental-based. Alongside municipal housing, limited-profit housing associations play a crucial role, running cost-based, long-term development and management models.
OECD statistics indicate that 41.7% of Vienna's population lives in social housing schemes. The average monthly cost was approximately €550 per apartment, compared to €807 on the private market—roughly 32% lower. The OECD emphasizes that a large affordable housing stock dampens overall rental price levels across Vienna.
The key lesson from Vienna is that rental housing does not have to be a temporary or lower-quality living option. At scale, backed by professional development and operations, it serves as a viable long-term option for the middle class. From a sustainability perspective, long-term single ownership is uniquely suited for implementing energy efficiency, lifecycle, renovation, and decarbonization strategies.
Poland – A Relevant Development Trajectory for Hungary
Historically, Poland shared Hungary's strong homeownership focus, yet it rapidly established a functioning institutional PRS sector. Developers and institutional investors there routinely acquire or build entire residential blocks specifically for long-term rental portfolios.
According to CBRE, by the end of Q1 2025, there were 24,400 operational institutional PRS apartments in Poland across 33 institutional investors—a 30% year-over-year inventory growth. Forecasts indicate the operational stock will exceed 37,000 units by year-end 2027, with an additional 12,800 units in the pipeline.
While still a modest share of Poland’s total housing stock, it represents a fast-growing, recognized asset class. It serves as a key benchmark proving that institutional rental sectors can emerge even within strongly owner-occupied Central European markets.
Three Markets – Three Starting Points
Metric / Aspect | Hungary | Poland | Austria |
Homeownership Dominance | Very High (~92%) | High | Lower (~54%) |
Renter Share | ~8% | Relatively low, but growing institutional sector | ~46% (Dominant in Vienna at ~80%) |
Institutional PRS/BTR | Emerging / Early | Rapidly Expanding | Mature Rental Ecosystem |
Social / Limited-Profit Sector | Small | Limited | Very Substantial |
Note on definitions: International definitions of social housing vary, so percentages require contextual interpretation. Based on the OECD Affordable Housing Database, Austria's social rental housing accounts for over 20% of its total housing stock, whereas Hungary and Poland belong to the 2–10% bracket.
What Does This Opportunity Mean for Hungary?
Implementing rental models in Hungary does not mean copy-pasting Vienna's approach. A hybrid evolutionary path is more realistic: a mix of market-rate BTR projects, institutional investors retaining whole buildings or large portfolios, combined with municipal or state "affordable rental" initiatives.
In professional rental developments, the service itself becomes part of the product: centralized maintenance, dedicated tenant service, community spaces, bike storage, parcel lockers, co-working spaces, and fitness facilities. Integrated sustainability improves operational quality while ensuring long-term control over building performance.
The primary hurdle remains financial viability: balancing high land and construction costs against affordable rents to yield acceptable investor returns. Sustainability measures must therefore be evaluated through a lifecycle and business lens rather than treated as superfluous capital expenses.
Sustainability Delivers Direct Business Value
Sustainability Aspect | Value Contribution in a Rental Project |
Energy Efficiency | Lower and more predictable energy demand; improved OPEX and tenant utility bills. |
Water & Metering | Enhanced cost control, operational transparency, and portfolio-level data collection. |
Indoor Quality & Comfort | Thermal comfort, air quality, acoustics, and daylight create a more attractive living environment. |
Durable & Responsible Materials | Reduced replacement and maintenance needs, lowering lifecycle costs and embodied carbon. |
Mobility | Bike infrastructure, EV charging stations, and strong public transit connectivity. |
ESG Data & Measurability | Better support for investor reporting, green financing, and compliance requirements. |
Climate Adaptation | Mitigation of overheating and other long-term physical climate risks. |
What Value Do BREEAM, EU Taxonomy, or Other Certifications Add?
We view the value of BREEAM, the EU Taxonomy, and other sustainability frameworks not in the certificate itself, but in the structured execution they enforce. The right system provides a clear blueprint for the developer and project team to define and document goals across energy, water, health and well-being, transport, materials, ecology, management, and operations from day one.
Documented sustainability performance supports ESG reporting, green finance eligibility, institutional investor due diligence, and future refinancing or asset sales. Determining which framework provides tangible leverage depends on the project's specific financing and exit strategy.
Our core philosophy: Certification should be a tool, not an end in itself. The objective is a rental asset that works technically, environmentally, and financially over the long term. |

How Greenbors Can Support Your Project
We generate maximum value when sustainability is embedded into the initial concept and investment decision rather than added right before completion. We support rental projects across their entire lifecycle:
Project Phase | Greenbors Consultancy Support |
Concept / Investment Decision | Sustainability opportunity assessment, pre-assessments for BREEAM and other rating systems, ESG/EU Taxonomy screening, climate risk and site assessments. |
Design Phase | Certification strategy, BREEAM Assessor/AP guidance, and coordination of energy, comfort, indoor air quality, water, mobility, materials, LCA, and ecology goals. |
Construction Phase | Contractor requirements and evidence management, tracking of materials, waste, commissioning, and performance verification. |
Handover / Operations | Commissioning oversight, energy and ESG data structure setup, and in-use certification feasibility assessment. |
Portfolio / Transactions | ESG and sustainability due diligence, benchmarking, EU Taxonomy alignment reviews, and decarbonization and retrofit roadmaps. |
We don't force pre-selected certifications onto a project. First, we analyze the owner's business, sustainability, and financing goals to determine which framework and advisory scope deliver actionable value.
Early Involvement Drives Better Outcomes
Whether you are a developer, investor, or design team considering BTR or other residential living concepts, evaluating sustainability, certification, and ESG opportunities early in the concept phase yields the highest return on effort.
The Greenbors team coordinates BREEAM and other green building certifications, ESG and EU Taxonomy criteria, and technical engineering requirements from concept design through construction to operations.
Even if a residential development was not initially conceived as a rental project, reviewing certification options mid-stream can unlock significant value. Minor adjustments can often elevate a project to meet higher sustainability tiers or EU Taxonomy criteria, making it substantially more appealing to institutional investors or green financing arrangements.
In the announcement of the Wekerle Program, the Hungarian Government estimated demand for at least 100,000 affordable rental units in Hungary. To meet this goal, the state intends to incentivize market-led developments while reviewing existing priority housing projects. A key dimension of these reviews will be evaluating social and environmental impacts—including transit connectivity, energy efficiency, and operational affordability.
International green building rating systems provide a proven, credible framework for these evaluations in Hungary. Whether for new pipeline developments or ongoing projects, our sustainability experts can quickly adapt your developments to meet these evolving market standards.
