An investor in Dubai is three documents away from wiring €800,000 into a renovated apartment building on the Athens Riviera. The lawyer has confirmed the title and the property’s eligibility under the residency rules. The remaining question is the asset itself: its condition, permits against its physical form, and capital expenditure across the residence-permit cycle. Those technical checks require a separate scope commissioned for the buyer.

Buyer-side technical due diligence exists for exactly this structure, and for Golden Visa acquisitions we run it as an independent engineering advisory whose fee never depends on the deal closing. The residency requirements themselves, thresholds, zones and qualifying assets, are set out in our guide to Golden Visa property requirements and technical risks. This article covers the verification step that belongs between reading that guide and signing anything. What that verification covers in full is set out in our guide to property due diligence in Greece.

Why the Golden Visa Structure Amplifies Technical Risk

Under Law 5100/2024, the minimum investment is €800,000 in Attica, the Regional Unit of Thessaloniki, Mykonos, Santorini and islands with more than 3,100 residents, and €400,000 elsewhere, in one property. This concentrates the qualifying investment in one asset. The residence permit is issued for five years and may be renewed while the qualifying property remains owned and the other conditions continue to be met. A sale affects the seller’s permit; the law does not impose a separate five-year minimum holding period.

Legal Due Diligence Is Not Technical Due Diligence

The Golden Visa process is lawyer-led, and the lawyers do their part well: title, liens, eligibility of the property, the immigration file. None of that touches the building. The structural condition, the moisture behavior, the electrical installation, the true state of a renovation, and the match between the permit file and the physical structure sit outside every mandatory check in the process, the same gap that runs through all Greek transactions and that lawyers themselves increasingly close by bringing in independent technical advisors, as we describe in how lawyers and buyers agents use technical advisors. An investor whose entire verification is legal has verified the residency and not the 800,000 euros. The two verifications cost about the same. Only one of them protects the capital.

BEFORE YOU COMMIT TO A GOLDEN VISA PROPERTY

Send the listing, floor plans, permit documents or agent material before signing anything.

We perform remote asset reviews for Golden Visa investors evaluating qualifying properties across Greece.

This early-stage review identifies: inconsistencies between the permit file and the marketed property, renovation quality signals in conversion and refurbishment assets, unsettled regularization exposure under Law 4495/2017, and whether the asset justifies a full on-site assessment before the investment is committed.

The review is independent, English-language and delivered directly to the buyer.

The Threshold Trap: Paying 800,000 for a 650,000 Euro Building

Threshold-driven markets develop a specific pathology: assets get priced at the threshold rather than at their value, because the seller knows the buyer needs to clear a number, not find a bargain. The premium is invisible until the technical layer is examined. A building with tired installations, a roof nearing replacement and an optimistic renovation carries a capital expenditure schedule that ordinary buyers would price into the offer, and threshold buyers routinely do not. Condition findings are the only instrument that reprices such an asset: they either justify the number, negotiate it down, or justify walking to the next qualifying property. The renovated-to-sell segment deserves particular scrutiny, and the lower 250,000 euro route for conversions of former commercial buildings and restorations of listed buildings, subject to its own conditions, concentrates renovation risk almost by definition.

The same logic applies to timing. The qualifying event is the transfer of funds, and every verification made before it costs the investor nothing but scheduling. A remote review of the permit file and renovation documentation takes days, an on-site assessment fits inside any realistic acquisition timeline, and both happen while the investor still holds the only leverage that matters in a threshold market: the ability to move the same 800,000 euros to a different qualifying asset.

What Investor-Grade Due Diligence Covers

The permit file is compared with the physical building, because unresolved violations can create cost and transferability exposure and the filing deadline for eligible older violations runs to 2028, as explained in our guide to building permit due diligence in Greece. The structure, envelope and installations are assessed by visual and functional examination, with findings priced into a capital-expenditure view across the residence-permit cycle. The EPC and current building performance are resale and operating-cost inputs. Any future EU or Greek minimum-standard obligation should be modelled only when a binding rule, scope and date apply to the asset.

Acquiring a Golden Visa Property in Greece?

Before contracts are signed, we review: the permit file against the built reality, structural and installation condition, renovation quality in refurbished and converted assets, regularization exposure under Law 4495/2017, and the capital expenditure the asset will demand across the holding period.

For Golden Visa investors and their advisors, we provide independent technical due diligence, property inspections and remote asset reviews across Greece, delivered in English directly to the buyer, typically within 7 working days.

Frequently Asked Questions

What are the Golden Visa investment thresholds in Greece?

Under Law 5100/2024, 800,000 euros in Zone A, which covers Attica, Thessaloniki, Mykonos, Santorini and islands with larger populations, and 400,000 euros in the rest of Greece, in a single property. A lower 250,000 euro route exists for conversions of former commercial buildings and restorations of listed buildings, subject to its own conditions.

Does the Golden Visa process include any inspection of the property?

No. The process verifies the investment amount, the title and the immigration file. No authority or professional in the mandatory chain assesses the building’s condition or measures it against its permits. Technical verification happens only if the investor commissions it independently.

Why does the five-year residence-permit cycle change the due diligence?

A sale during the permit’s validity affects the seller’s residence permit under the current rules, so exit and residence planning should be reviewed together with immigration counsel. Defects found after purchase are also harder to negotiate with the seller. Due diligence therefore prices condition and capital expenditure before commitment and across the intended ownership period.

How much does technical due diligence cost for a Golden Visa property?

A property inspection from an independent technical advisor starts from €5,000, with technical due diligence scoped to the size and complexity of the asset. That starting price equals 1.25% of a €400,000 investment and 0.625% of an €800,000 investment before any scope adjustment.
