Greece’s closed property stock: just 10% immediately exploitable

This is reflected in data from the international FREI index, which classifies properties based on whether they can be inhabited, leased, sold, or otherwise utilised without institutional, legal, or technical barriers.

A key finding is also that only 10% of the total stock of closed properties in Greece is immediately usable. In other words, a very large share of the apparent housing stock remains essentially “inactive.” It exists on paper, but is not ready to meet real housing or investment needs.

One-third of total properties in Greece remain unused

According to the FREI Funnel diagram used in the digital mapping and assessment process developed by Blupeak Estate Analytics, 32% of Greece’s total property stock remains unused. Of this pool, only 25% is formally recorded, highlighting an early loss of visibility and structured information regarding the true state of the market.

This is followed by the stage of technical suitability, where the share drops to 14%, indicating that a significant portion of the stock either requires interventions or cannot be immediately brought to market.

The distinction between categories of real estate is crucial for its utilisation. A property that is recorded but has unclear ownership status, pending cadastral issues, zoning problems, or incomplete technical documentation is not truly available. It is formally registered, but practically inactive.

Illustrative scenario: From 100 municipal properties, only a small share is ready for use

The broader picture of municipal real estate often creates the impression that local authorities have significant room to contribute to housing and local development. However, the reality is far more complex. The illustrative scenario presented in the BluPeak Estate Analytics chart shows that out of 100 properties, only a small portion can be used immediately, while a substantial share remains frozen or requires prior corrective action.

Specifically, only about one-quarter of the total stock is immediately usable—properties that can quickly be activated for housing, social, or development purposes without lengthy maturation processes.

At the same time, roughly four in ten properties fall into the category requiring minor interventions. These are not excluded from utilisation, but require technical, administrative, or operational adjustments before they can be activated. In other words, they represent a stock that can be unlocked, provided there is an organised management framework.

There is, however, a third equally critical category: blocked properties. In this case, they represent a significant share of the portfolio and are constrained by legal, institutional, administrative, or other major barriers. As long as these obstacles persist, such properties cannot function as real policy tools, even if they formally belong to municipal assets.

European comparison: better data, better utilisation

While Greece still faces challenges in mapping public real estate, several European countries have already adopted a different approach: full registration and active management. In the Netherlands and Denmark, for example, integrated digital registries link ownership, zoning, and technical data in unified platforms, allowing municipalities and public bodies to know in real time which properties are available and in what condition.

In Germany, the use of geospatial systems and property registers has been incorporated into housing policy design, while in France systematic recording of public assets supports social housing programmes and public–private partnerships. The common factor is not the quantity of real estate, but the quality of data, which enables clear assessments and targeted interventions.

Growing demand for transparency and oversight

These insights are reinforced by a recent survey conducted by Blupeak Estate Analytics in collaboration with Ierax Analytix. The findings highlight a strong social demand for greater transparency and more effective oversight of the real estate market.

Among respondents aged 25–35, 82% believe that lack of control directly affects prices, while 75% consider digital registration of all properties important. In the same group, 81% state that their housing situation influences major life decisions, indicating that housing has evolved from a purely economic issue into a broader social pressure factor.

A similarly strong signal emerges among older age groups. In the 36–55 cohort, 70% consider the creation of a unified public Property Register important, while 60% believe such a tool could help stabilise prices. At the same time, 72% believe that the utilisation of public assets could act as a buffer against the housing crisis.
