Greek Golden Visa €250,000: The Commercial-to-Residential Conversion Option

The €250,000 Greek Golden Visa is the only investment option that keeps the old threshold after the Law 5100/2024 reform, applying to two specific cases: buying a commercial property for conversion to residential use, or buying a state-recognised heritage building for restoration. This article focuses on the first case — the far more common option, with legal specifics of its own compared with buying an ordinary residential property.

It is the only option that lets investors enter the Golden Visa with a budget under €400,000, without being restricted by the geographic zoning of Greece and requires no minimum floor area. In return, however, investors must accept a more complex legal process, risks related to the change of use, and certain special restrictions on using the property afterwards.

Legal Basis of the €250,000 Greek Golden Visa

The commercial-to-residential conversion option is set out in Article 100 of Migration Code 5038/2023, as amended by Article 64 of Law 5100/2024. Under this provision, the minimum threshold of €250,000 applies to a property purchase where the main floor area is converted to residential use. The scope is not restricted by geographic zone, including Zone A areas such as central Athens, Thessaloniki, Mykonos or Santorini.

The regulation also clarifies a special case for industrial property: an investor is only eligible under this option if the industrial building has had no production activity for at least 5 consecutive years before the purchase date. This requirement is meant to stop operating businesses being displaced so their premises can be converted into Golden Visa housing, which would harm local economic activity.

According to the Greek Ministry of Migration and Asylum, Circular 1/2026 of 22 April 2026 standardised the full set of documentation required for this option, including notarial deeds, title certificates, engineers’ technical reports, insurance, and the E9 property declaration form. This standardisation shortens processing time and limits inconsistent interpretation between receiving authorities.

Two Eligible Conversion Cases

Case 1 — Commercial Property to Residential

The first case applies to common types of commercial property, including offices, shops, service premises, small warehouses and multi-purpose units. The only requirement is that the building holds a valid building permit and is registered for commercial use with the local Town Planning Authority before conversion. There is no requirement on how long commercial use must have ceased beforehand.

This means an investor can buy an office that is currently leased, sign a lease-termination agreement, and then proceed to convert it to residential use without waiting. This is the most common property type on the Golden Visa conversion market, especially in central Athens districts where many older buildings mix office and residential space.

Case 2 — Industrial Property to Residential

The second case applies only to industrial buildings such as factories, large warehouses and production facilities. The legal requirements are stricter: the investor must prove there has been no industrial production activity for at least 5 years before the purchase date. Supporting documents include confirmation from the Tax Authority (AADE) that there is no business activity, electricity and water statements showing minimal consumption, and confirmation from the local authority.

This option suits loft-conversion projects in Athens’s former industrial suburbs, such as Tavros, Egaleo and Eleonas, which are now undergoing urban regeneration. The entry price of industrial property is typically 30-50% cheaper than commercial property in the same area, but renovation costs are higher because of structural and technical-system changes.

Technical Requirements of the €250,000 Greek Golden Visa

Unlike Zone A and Zone B, the conversion option has no minimum floor area of 120 square metres. An investor can buy a 60-square-metre office in central Kolonaki, Athens, for €250,000 after conversion, provided the other technical conditions are met. This flexibility is the option’s biggest advantage over the other two zones.

The core requirement is that the change of use must be legally completed before the Golden Visa application is submitted. Specifically, the new registration certificate at the Hellenic Cadastre must state the use as “residential” rather than “commercial” or “industrial”. This process usually takes 6-12 months from filing the change-of-use application with the Town Planning Authority, depending on the building’s complexity and the local administration’s capacity.

The third requirement is a single property unit, as under Zone A and Zone B. In a co-ownership case, each co-owner must invest a minimum of €250,000 to be granted their own Golden Visa, except where spouses hold undivided joint ownership, in which case only a combined minimum price of €250,000 is required.

The Change-of-Use Process

Step 1 — Technical and Legal Survey

Before placing a deposit, the investor needs to hire a licensed Greek building engineer to carry out a technical survey. The technical report must clearly establish whether the building can be converted to residential use, based on criteria such as load-bearing structure, whether the electrical and water systems can be upgraded, natural light meeting the required standard, and compliance with the area’s urban plan. Some buildings within strict commercial zoning will not be permitted to convert.

At the same time, a property lawyer checks the legal file: the original building permit, title registration, transaction history, any building violations needing legalisation, and — for industrial property specifically — documentation of the period of inactivity. This survey step typically costs €2,000 to €5,000 but avoids the risk of losing the deposit through ineligibility for conversion.

Step 2 — Purchase the Property and Apply for a Change-of-Use Permit

Once conversion feasibility is confirmed, the investor signs the sale contract at a notary’s office and registers title at the Cadastre. Next, the investor files a “change of use permit” application with the district Town Planning Authority. The file includes the conversion design drawings, the technical report, and evidence of compliance with building and energy codes.

Approval takes 3 to 9 months depending on locality. Central Athens has a clearer process but a heavy caseload, while smaller towns can be faster but demand more supporting documents. During this stage, the investor already owns the property but cannot yet use it as housing.

Step 3 — Construction and Final Inspection

After receiving the change-of-use permit, the investor carries out the conversion works. The scope of work depends on the extent of change: from light renovation (partitioning rooms, fitting a kitchen and bathroom) for a former office, to major renovation (structural changes, electrical and water systems, soundproofing) for industrial property. Renovation costs typically run from €300 to €1,500 per square metre depending on scope.

After construction, the investor requests a final inspection from the Town Planning Authority and updates the certificate at the Cadastre. Once the new registration states the use as “residential”, the legal conversion is complete. Only then is the investor eligible to apply for the €250,000 Greek Golden Visa.

Specific Restrictions of the Conversion Option

Besides the general restrictions of the Greek Golden Visa, such as the ban on short-term rental (Airbnb) and the ban on sub-letting, the conversion option carries one further specific restriction: the property may not be used as the registered seat or branch office of any business. This rule is meant to prevent the conversion option being exploited to keep a property in a “hybrid” state between commercial and residential.

Breaching any of the above restrictions results in an administrative fine of €50,000 and revocation of the residence permits of the entire family. According to the Ministry of Migration and Asylum, this is the highest penalty among European Golden Visa regulations, reflecting the Greek government’s firm stance on protecting the long-term housing market.

Another practical limitation is the cost that accrues on top of the purchase price. The real total cost of the €250,000 option usually reaches €280,000-€330,000, including notary fees, transfer tax (3% of the contract price), engineer and lawyer fees, renovation costs, and permit fees. Investors need to work out the full total cost before deciding.

According to the Bank of Greece, commercial properties in central Athens are priced 20-30% lower than residential property in the same location. This price gap creates an arbitrage opportunity for investors able to manage a conversion project: buying a low-priced office, converting it, and owning residential property in a central location for a much lower total cost than buying residential property outright.

Who It Suits and Who It Does Not

The €250,000 Greek Golden Visa option suits three specific groups of investors. The first is investors with a limited budget who prioritise EU residence at the lowest possible cost and do not mind a complex process. The second is investors who understand the Athens market and can assess conversion potential and manage a project remotely through a local partner. The third is investors who particularly love the central Athens lifestyle and want to own a converted apartment in a classic building.

This option does not suit investors who prioritise fast liquidity, do not have 12-18 months to follow a project, or lack a trustworthy partner in Greece to supervise construction. For investors with a budget above €400,000 who want a simpler process, the Greek Golden Visa Zone B €400,000 option is legally the safer choice.

For investors with a larger budget who still want to enter central Athens, it is worth weighing the €250,000 conversion option (accepting a complex process in exchange for a lower price) against the Zone A €800.000 option for an existing residential unit (no conversion needed). A specific project-by-project cost comparison is necessary before deciding.

Summary

The €250,000 Greek Golden Visa commercial-to-residential conversion option opens the door to the EU at the lowest budget among the programme’s options, while allowing ownership of property in premium locations such as central Athens, Thessaloniki or the major islands, which would otherwise require €800,000 under the standard residential option. However, investors must accept a 6-12 month change-of-use process, additional renovation costs, and the specific restriction banning use as a business’s registered seat.

The next step for investors considering this option is to survey the commercial property market in Athens, assess the capability of local engineer, lawyer and contractor partners, and draw up a detailed financial plan for all three stages: purchasing the property, legal conversion, and construction.
