Timing is one of the most important eligibility questions in an EUR 250,000 Greece Golden Visa conversion project. A buyer may see a finished apartment, a signed purchase agreement and a complete payment file, yet the immigration file still depends on when the underlying commercial-to-residential change of use was completed and how that date is documented. The official Greek procedure now gives a clear sequence: the qualifying change of use must fall within the statutory framework and must be completed before the Golden Visa application is submitted.
This article explains that sequence for buyers comparing Santheos Greece Golden Visa conversion projects in Athens. It focuses on the property file, not on an applicant’s personal circumstances.
The official timing rule
The English-language National Registry of Administrative Public Services describes the special procedure for real estate undergoing a change of use from commercial to residential. It states that the change of use must have been completed after Article 64 of Law 5100/2024 entered into force on 5 April 2024 and before the Golden Visa application is submitted.
That sentence creates two separate checkpoints. First, the relevant qualifying action must sit on the correct side of the 5 April 2024 date. Second, the change-of-use work in the legal and technical file cannot remain incomplete when the residence-permit application is filed. A reservation, construction schedule or intention to convert is not the same as a completed and documented change of use.
What if an older permit already existed?
Some buildings had planning approvals or permits issued before the new framework was published. The official procedure addresses this situation directly. Where the permit for change of use predates the law, an application is accepted only when the file for the specific property was updated or revised for a relevant reason after publication of the law.
This makes the date on the oldest permit only one part of the review. The buyer’s engineer and lawyer should examine the complete history: the original permitted use, the document that authorised or recorded the conversion, every later update or revision, and the final technical report prepared for the Golden Visa file. A generic statement that “the building was converted” does not establish the required chronology.
The buyer or seller may complete the conversion
The official procedure also states that the change of use may be carried out by either the buyer or the seller. In a developer-led project, the seller may organise the planning, technical and construction sequence before transfer. In another transaction, the buyer may assume responsibility for completing a qualifying conversion after acquisition.
The commercial structure changes the order of documents, responsibilities and payment milestones. It does not remove the requirement that the change of use be completed before the Golden Visa application. Buyers should therefore ask who is responsible for each step, what evidence is delivered at transfer, and what must still occur before filing.
A practical document sequence
A well-organised conversion project normally allows the professional team to trace the property through a consistent sequence:
- confirm the title, cadastral identity and boundaries of the single property;
- identify the legally recorded use before conversion;
- review the building permit, small-scale works approval, file update or permit revision relied upon for the residential use;
- confirm that the qualifying post-5 April 2024 requirement is met;
- complete the conversion and collect the supporting technical records;
- prepare the engineer’s technical report in the form required for the change-of-use Golden Visa procedure;
- complete the notarial and payment evidence; and
- submit the residence-permit application with the required property and applicant documents.
The exact sequence varies by project, but the evidence should tell one coherent story. Dates, property descriptions and names should match across the permit file, engineer’s report, deed, land-registry evidence and immigration submission.
Questions to ask before reserving a unit
Before committing to a particular unit, request a property-specific explanation of the route. Which document proves the former commercial use? Which act records or confirms the residential use? Was an older permit updated or revised after 5 April 2024? Who signs the engineer’s report? When will the report be available? Does the deed identify the same property and use described in the technical file?
These questions are especially important in multi-unit developments. The EUR 250,000 route concerns a single property, and the file must connect the purchased unit to the conversion evidence. Marketing material for the wider building cannot replace the records for the exact property being transferred.
Why filing too early creates avoidable risk
Submitting before the technical sequence is complete can create inconsistencies or missing-document requests. The official process includes a completeness check of the supporting documents. If the engineer’s report cannot yet confirm the completed change of use, the central property condition has not been documented for the application file.
A disciplined project timetable therefore works backwards from the intended filing date. It leaves time for technical completion, professional review, corrections to names or property references, completion of the deed and land-registry steps, and assembly of the digital application file.
How Santheos organises the review
Santheos develops and presents fully eligible EUR 250,000 Greece Golden Visa commercial-to-residential conversion projects in Athens. For each project, the development, engineering, legal and risk-control teams organise the project documentation, conversion delivery and handover sequence so that the relevant professionals can review the exact property file.
Buyers should still work with their appointed lawyer, notary and engineer when reviewing a transaction. The useful question is not simply whether a project is described as a conversion, but whether the complete chronology and technical evidence support the specific unit.
Official source and next steps
The primary reference is the Greek government’s English procedure, Permanent golden visa (change of use) – Initial issuance. It should be read together with the current legislation and property-specific professional advice.
