From Empty Offices to New Homes: How Greece’s €250,000 Conversion Framework Could Reshape Athens’ Housing Market

Santheos Greece Golden Visa conversion project image

For much of the past decade, debate around Greece’s Golden Visa focused on demand: how many investors entered the property market, how much capital they brought and whether that purchasing power contributed to rising prices. The programme’s €250,000 change-of-use route raises a different question: what happens when international investment helps create homes instead of only purchasing homes that already exist?

The verified policy framework

Verified fact. Greece’s National Registry of Administrative Public Services states that the change-of-use Golden Visa route has a minimum investment value of €250,000. The investment must concern a single property. The 120-square-metre condition that applies to certain other property routes does not apply to this category. The change to residential use must have taken place after 5 April 2024 and must be completed before the residence-permit application is submitted. A separate five-year inactivity requirement applies when an industrial building is converted.

This is a route with legal and technical conditions, not a general promise that any office or commercial property is eligible. Title, lawful use, permit history, timing, acquisition value, payment evidence and completed conversion all require property-specific review. The words “fully eligible” should be used only when the relevant project documents have been checked and the conclusion has been confirmed.

Athens has a housing-supply problem

Verified fact. Eurostat’s Housing in Europe 2025 reports that in 2024, 29% of people living in Greek cities were in households where housing costs exceeded 40% of disposable income—the highest urban housing-cost overburden rate in the European Union.

Verified fact. Greece’s National Housing Strategy 2026–2035, approved in August 2026, sets out 50 measures, including 14 proposed measures, across three policy axes. One axis focuses on increasing housing supply. The strategy describes a multi-year programme exceeding €6.5 billion; implementation details and proposed measures should be monitored separately from enacted law.

Verified fact. Provisional Bank of Greece data show that Athens apartment prices increased by 5.2% year on year in the first quarter of 2026. Price growth alone does not prove a shortage, but it is consistent with continuing pressure in the market.

Why smaller homes matter

Verified fact. ELSTAT’s 2021 Population and Housing Census records 1,639,402 private households in Attica. Of these, 570,487 were one-person households, an increase of 36.9% compared with 2011.

Lei Chen’s analysis. A city can have a large housing stock and still lack the right kinds of homes in the right places. The growth of one-person households strengthens demand for smaller, well-connected apartments. A 35–60 square metre home uses limited floor area but can meet one complete household’s need. That makes lawful conversions of obsolete offices potentially relevant to students, young professionals, separated households, retirees and internationally mobile residents.

From housing demand to housing production

Historically, a Golden Visa purchase often transferred ownership of an existing apartment. Capital entered Greece and the home might be renovated, but the number of homes did not necessarily rise. A lawful commercial-to-residential conversion can change that equation when obsolete floor area is turned into usable residential units.

Lei Chen’s analysis. The economic significance is not that every €250,000 investment automatically creates one additional home. Some buildings may contain mixed uses, and unit creation depends on the approved design and works. The important change is that the framework can reward projects which add usable residential supply while recycling buildings that no longer serve their original economic purpose.

What would 6,000–7,000 units per year mean?

Illustrative scenario—not an official statistic. There is no public Greek administrative series that isolates annual residential units completed specifically through the €250,000 change-of-use Golden Visa route. To test possible market impact, assume the development industry produces 6,000–7,000 converted residential units per year across Attica. Two years would equal 12,000–14,000 units. Including projects under construction could place a high-end pipeline scenario near 15,000.

Against Attica’s 1.64 million private households, 12,000–14,000 units equal about 0.7%–0.9%. Compared with the 570,487 one-person households recorded in 2021, they equal approximately 2.1%–2.5%. These comparisons do not forecast occupancy or rents. They show why a supply programme concentrated in the small-apartment segment could matter more than its share of the entire housing stock suggests.

If 70% of the illustrative 12,000–14,000 units supported longer-term residential occupation, that would equal 8,400–9,800 homes. At 80%, the range would be 9,600–11,200. At 90%, it would be 10,800–12,600. These are arithmetic sensitivity tests, not predictions.

Early market signals require caution

Market-platform data. XE reports that advertised Athens rentals of up to 80 square metres increased from 9,894 in the second quarter of 2025 to 10,680 in the second quarter of 2026, a rise of 7.9%. Over the same period, the average advertised rent rose from €12.03 to €12.70 per square metre, an increase of 5.6%.

This does not demonstrate that conversions caused the growth in listings, nor that new supply reduced rents. Listings are not the total rental stock and can change because of tenant turnover, seasonality and landlord behaviour. The figures instead illustrate an important analytical point: supply may expand while rents continue to rise when underlying demand is expanding faster. The useful counterfactual is not only “did rents fall?” but also “how much higher might they have risen without additional homes?”

Why conversions can matter locally

Housing markets operate at the margin. If a neighbourhood normally has only 200 suitable small apartments available and several projects add 300 units over 18 months, tenants gain choice and landlords face more competition. Poor-quality apartments can become harder to rent at premium prices, while developers must compete on design, energy performance and service.

Conversion also uses a resource Athens already has: built floor area. A structurally suitable but economically obsolete office may already have road access, utilities and a location close to employment or public transport. The legal change-of-use route can therefore act as a form of urban asset recycling. However, conversion is not automatically faster or cheaper than new construction; structural, fire-safety, accessibility, daylight, energy and permitting constraints can materially change cost and timing.

Build-to-Rent points in the same direction—but is separate

Verified government announcement. In January 2026, the Greek government announced a Build-to-Rent programme under which legal entities could construct homes or convert buildings from other uses and commit them to long-term rental for at least ten years at predetermined rents. This is a separate housing-policy measure and should not be confused with the Golden Visa change-of-use route. Its final legal and tax operation must be checked against the applicable enacted provisions.

Lei Chen’s analysis. Taken together, the direction of policy is notable: capital is increasingly being judged not only by how much enters the country, but also by what it adds—housing supply, reuse of inactive assets and longer-term residential capacity.

Risks and limits

  • Housing is not automatically affordable. A new studio may still be priced above local purchasing power.
  • The €250,000 threshold can become a price anchor. Competition for suitable commercial buildings may raise acquisition prices.
  • Segment risk remains. Too many studios in one micro-market can coexist with a shortage of family-sized homes elsewhere.
  • Delivery risk is material. Permit history, building condition, construction cost and completion timing can undermine an apparently attractive project.
  • Residence-permit eligibility is property-specific. Marketing descriptions do not replace legal, technical and immigration review.
  • Rental rules and tax treatment can change. Investors must check current law and the specific permitted operating model before commitment.

Investor due-diligence checklist

  1. Confirm ownership, cadastral records, encumbrances and the property’s lawful existing use.
  2. Trace the permit chain and verify that the change to residential use is lawful, completed after 5 April 2024 and completed before the residence-permit application.
  3. If the asset is industrial, confirm the special five-year inactivity requirement with documentary evidence.
  4. Confirm that the investment concerns one property and that the acquisition value and payment trail satisfy the applicable route.
  5. Obtain an architect’s review of structural suitability, fire safety, accessibility, natural light, energy performance and unit layout.
  6. Check the construction contract, specifications, milestones, completion protections and handover evidence.
  7. Verify the current rules for short-term, medium-term and long-term use; do not rely on sales language.
  8. Stress-test rent, vacancy, operating costs, tax, common expenses and resale assumptions.
  9. Ask property-specific Greek legal, technical, tax and immigration advisers to sign off before commitment.

The programme may ultimately be measured in homes

For years, Golden Visa performance was measured in permits and euros invested. The next phase needs additional metrics: obsolete buildings converted, genuinely new residential units created, unit sizes, locations, completion dates, lawful occupation and local rent outcomes.

The €250,000 framework cannot solve Athens’ housing challenge on its own. But if it helps turn obsolete commercial space into thousands of lawful, usable homes, it may improve the supply-demand balance in one of the most constrained parts of the market. Athens does not simply need more property investment. Athens needs more homes.

Data and methodology note

No official Greek administrative series currently isolates completed residential units created each year specifically through the €250,000 commercial-to-residential Golden Visa category. The 6,000–7,000 annual, 12,000–14,000 two-year and 15,000 pipeline figures are illustrative scenarios for market-impact analysis, not government statistics or Santheos delivery forecasts. Marketplace listings indicate advertised supply and asking prices, not the total housing stock or completed transactions. All legal, tax, planning and residence-permit conclusions require current, property-specific professional review.
