Property valuation in Greece 2026
✦ Key Takeaways
- A property's market value is not the same as its tax value.
- An online valuation gives you a first indication — usually a range, not a single exact figure.
- An accurate market valuation takes solid comparables and knowledge of the local market, not just an average price per square metre.
- Asking prices in listings are not final sale prices.
- Official uses require a duly certified valuer.
Property valuation is the process of determining a property's market value at a specific point in time. Whether you're preparing to sell an apartment or want to know what your home is worth before an investment decision, a proper valuation is where every informed property decision starts.
The right method depends on the purpose: a quick online valuation is enough for a first impression, while a certified report is needed when the valuation will be used for an official purpose.
What is property valuation?
Property valuation determines the market value — the price at which a property could realistically be sold in the current market, under normal transaction conditions.
This value isn't fixed. It shifts with market conditions and timing, even with individual transactions in the same neighbourhood. That's why a market valuation only holds for a specific point in time — not indefinitely.
It also pays to distinguish three different figures: the estimated value (what the property is actually worth), the asking price (what the seller lists it for), and the final sale price (what was actually agreed). These rarely match — and mixing them up is the most common cause of mispricing.
Market value vs. tax value: what's the difference
One of the most common points of confusion is between market value and tax value.
Market value is what the market determines — what a buyer is willing to pay today. Tax value is an administratively set value, based on zone prices and coefficients, used by the tax authority to calculate taxes such as ENFIA or property transfer tax.
The two can diverge significantly. A property in a sought-after area may have a market value well above its tax value; in a declining market, the opposite can happen. The zone price doesn't tell you what the property will actually sell for — it only reflects the tax base. Some of the property purchase costs are calculated on this tax value, which is why the distinction matters before you proceed.
How property valuation works: the 5 steps
The logic follows the same structure whether a professional or a more thorough online tool does the work — simpler tools just skip some of the steps.
1. Gathering property data. Location, size, use, floor, age, condition, layout, auxiliary spaces.
2. Analysing the area and market. Micro-location, access, infrastructure, current supply and demand in the specific area.
3. Selecting comparable properties. Properties in the same area, similar category, size, condition and age — recently sold or listed.
4. Adjusting the comparables. Every difference matters: floor, view, renovation, parking, storage, energy class, overall building condition.
5. Setting a value range. A proper valuation gives a range, not an artificially precise figure — no set of comparables is ever a perfect match for the property being valued.
What factors affect a property's value
Location and micro-location. It's not just the area or municipality — the specific street, noise levels, view, access and distance from transport all matter. Two apartments in the same building can have different values simply because of floor and view.
Size, layout and floor. Value isn't just square metres multiplied by an area average — how functional the layout is matters just as much.
Age, condition and energy performance. The building's age, construction quality and energy class directly affect both market value and your negotiating position when selling.
Legal and planning status. Unauthorised building works, discrepancies in declared surface area, or title issues can delay or block a transaction altogether, beyond their effect on value. If your property has any outstanding issues, see our guide on unauthorised construction in Greece — and make sure the property's Electronic Building Identity is in order, since no transfer can proceed without it.
Supply and demand. The overall state of the local market — how many comparable properties are available and how quickly they're absorbed — affects final market value more than most people realise.
How online valuation works, and how reliable it is
Online valuation tools work on a simple logic: they start from a base price per square metre for the area, then apply percentage adjustments for size, age, floor, condition and energy class. The result usually comes as a range rather than a single figure — and that's a feature, not a limitation.
When it's useful. For a first impression, initial orientation, or comparing properties in areas with many similar listings, a free online valuation is a solid starting point.
Its limitations. It doesn't always include a site visit, it may rely on asking prices rather than actual sale prices, and it can't properly account for a property's unique features or technical and legal issues.
Online valuation, agent market appraisal, or certified valuation?
| Type | Best for | What it offers | Main limitation |
|---|---|---|---|
| Online valuation | A first indication of value | An instant range based on area data | Doesn't include a full site visit |
| Agent market appraisal | Selling or leasing | Local market knowledge, comparables, pricing strategy | Not a formal report for every use |
| Certified valuation | Bank, court, corporate or official use | A documented report suited to the specific purpose | Requires time, data and a fee |
Our view: the most common mistake isn't picking the wrong tool — it's treating an indicative online valuation as if it were a formal report. Use a digital valuation for orientation, but base your final asking price on up-to-date comparables and current knowledge of the local market.
Why listing prices aren't the real value
If you base your valuation only on local listings, you're starting with a distorted picture. A listing shows what the owner is asking — not necessarily what the property will actually sell for. Overpriced properties also tend to sit on the market longer, which skews any simple average of asking prices.
A reliable valuation needs careful selection and weighting of genuinely comparable properties — ideally based on actual transaction data, not just active listings.
When you need a property valuation
Valuation is needed in a wide range of situations, and the purpose determines the right type of valuation:
- Before selling or buying — for correct initial pricing. Browse our current commercial properties for sale for a first sense of the market.
- For setting rental levels — where an accurate valuation is essential to the returns on leased income properties.
- For investment evaluation — before deciding how to evaluate an investment property.
- For a bank loan or as collateral.
- For inheritance, distribution or a legal dispute, where the inheritance acceptance itself often needs to be finalised first.
- For corporate, accounting or other official use.
Not every type of valuation suits every situation — an indicative online valuation, for example, doesn't replace a formal report for court or bank use.
How much a property valuation costs
The cost of a property valuation varies by type:
- Online tools are usually free.
- Agent market appraisals are often offered as part of a potential sale or lease mandate.
- Certified reports are a paid service.
The final cost depends on the property type, size, location, purpose of the valuation, complexity of the case, and the documentation required. Because it varies so much case by case, a general figure would be meaningless — get in touch for a valuation tailored to your property.
Example: calculating an apartment's market value
An 85 sq.m. apartment in a given area has a base market price of around €2,200/sq.m., based on three recent comparable properties in the same micro-area. Adjustments are then applied:
- +5% for renovated condition
- +3% for view and good orientation
- −4% for lack of a parking space
- +2% for energy class B instead of C (the area average)
In this simplified example, the adjustments are applied sequentially to illustrate the process, rather than simply added together. The resulting market value range comes to roughly €2,310–2,350/sq.m., or €196,000–200,000 in total for the 85 sq.m.\*

💡 Tip: When comparing properties, check whether the reference prices are asking prices or actual sale prices — the gap between the two can be significant.
How to get a first estimate yourself — and the mistakes to avoid
If you want a rough first estimate on your own:
- Look at properties in the same micro-area, not just the same city.
- Match the category and similar size.
- Discard outliers or non-comparable results.
- Check floor, age, condition and amenities.
- Don't rely only on the highest price per square metre in the area.
- Work out a value range, not a single figure.
The most common mistakes: emotional overvaluation of the property, comparing with a property in a different micro-area, relying only on the average price per square metre, treating the asking price as the final price, assuming renovation costs are fully added to value, and overlooking legal or planning issues.
Setting the wrong asking price from the start isn't a harmless mistake — it affects how long the property stays on the market and your negotiating position. We'll cover exactly how valuation connects to selling strategy in a separate guide.
