How much is my apartment in Slovenia worth?
The quickest way to find out is an estimate based on what similar apartments actually sold for: VERICITY calculates one for every apartment in Slovenia from all registered sales, free and in seconds. The official value (posplošena vrednost) from the Surveying and Mapping Authority (GURS) is often below the market price, and for a mortgage or a court case you need a certified valuation (cenitev).

The short answer: three ways to a value
- An estimate from registered sales (VERICITY): free, in seconds, with a likely range. Its typical error against prices actually paid is 12.2%.
- The official value (posplošena vrednost): calculated by the state for every property. It is free, but it reflects the market on 1 January 2025, so it is often below today's market price.
- A certified valuation (cenitev): made by a licensed valuer or a court appraiser, usually after a visit. Banks require one for a mortgage, and it costs a few hundred euros.
| Route | Who makes it | Cost | When to use it |
|---|---|---|---|
| VERICITY estimate | an AI model trained on registered sales | free (PDF report €8.99) | selling or buying, negotiating, checking an ad |
| Official value (posplošena vrednost) | the Surveying and Mapping Authority (mass valuation) | free | public purposes set by law; a reference point |
| Certified valuation (cenitev) | a licensed valuer (pooblaščeni ocenjevalec) or a court appraiser | about €250 + VAT at banks | mortgages, court and other official procedures |
How the VERICITY estimate works
The estimate comes from an AI model trained on 95,468 registered apartment sales in Slovenia since 2010. Every sale comes from the real estate market register of the Surveying and Mapping Authority of Slovenia (GURS): the price in the contract, the date, the location, and the apartment's and building's details from the property register. For your apartment, the model compares these details with sales of similar apartments nearby and takes into account how prices have moved since.
That is why the estimate is not a single number: it also shows the range in which the price most likely lies.
How accurate it is
We check accuracy on sales the model never saw while learning. For sales from 1 August 2025 onwards, the typical error was 12.2%: half of the estimates were closer than that to the price actually paid. Estimates are most accurate in Ljubljana, where there are the most sales.
| Area | Typical error | Within ±10% | Within ±20% | Sales checked |
|---|---|---|---|---|
| all of Slovenia | 12.2% | 41.7% | 72.4% | 4,841 |
| Ljubljana | 10.5% | 46.3% | 79.2% | 1,101 |
| Maribor | 11.3% | 44.3% | 76.4% | 677 |
| the coast | 11.1% | 48.1% | 73.9% | 310 |
| elsewhere | 13.4% | 38.5% | 68.6% | 2,753 |
Estimates for sales from 1 Aug 2025 on, which the model did not see while learning. The typical error is the median gap between the estimate and the price actually paid.

What moves an apartment's price
The PDF report splits the estimate into groups of factors. For most apartments these matter:
- Location: the municipality, the neighbourhood and the street, including schools, public transport and shops nearby.
- The price level on the day: apartment prices in Slovenia rose by 11.5% over the last year, so older sales are brought to today's level.
- Size: smaller apartments fetch more per square metre, larger ones more in total.
- Floor: the ground floor, and the top floor without a lift, usually sell for less than the floors in between.
- The building: its type and size, the number of floors, a lift.
- Age: the year the building was built.
- Renovation: a new roof, facade, windows or installations recorded in the property register.
- A balcony or loggia and other parts of the apartment.
- Nuisance zones: noise along roads and railways, power lines and other zones recorded by GURS.
The model does not see inside the apartment. If it has just been refurbished, has an exceptional view or needs a full renovation, the real price will be above or below the estimate. That is why it shows a range.
What apartments cost now
Over the last 12 months (to 27 August 2026), apartments in Slovenia sold for a median of €3,243/m², 11.5% more than a year earlier. The typical apartment sold had 51.5 m² and cost €164,000. Across the country, 4,740 free-market sales of apartments were registered in that time.
| Municipality | Median €/m² | Change in a year | Sales in 12 months |
|---|---|---|---|
| Ljubljana | €5,277/m² | +12.1% | 1,088 |
| Maribor | €2,866/m² | +15.8% | 658 |
| Celje | €2,860/m² | +8.9% | 245 |
| Kranj | €3,829/m² | +9.2% | 174 |

Example: Štefanova ulica 1, Ljubljana
Each building's page shows the apartment sales in it over the last 15 years. At Štefanova ulica 1, Ljubljana, built in 1933, 10 apartment sales were registered in the last ten years, at a median of €3,832/m². Choose an apartment on the Štefanova ulica 1, Ljubljana page to get its estimate with a range and a comparison with its official value.
The official value is not the market price
If you own property in Slovenia, you may have received a letter from GURS with its posplošena vrednost, the official value it calculates for every property by mass valuation. The current values apply from 13 May 2025 and reflect the market on 1 January 2025. You can look up any property's official value for free in GURS's public viewer, which is in Slovenian: for an apartment, choose the Del stavbe tab and enter the address.
Prices have risen since, and a model for the whole country cannot see what sets one apartment apart from the next. Apartments sold since 13 May 2025 went for a median of 13% more than their official value, and 72% of them sold above it. VERICITY shows each apartment's official value next to its market estimate.
When you need a certified valuation
The VERICITY estimate is for information and is not a certified valuation. For a bank or another official procedure you need a valuation by a licensed valuer (pooblaščeni ocenjevalec vrednosti nepremičnin); in court cases the court appoints a court appraiser (sodni cenilec). Banks' price lists put an apartment valuation at about €250 plus VAT.
What the PDF report adds
The free estimate tells you what the apartment is worth. The PDF report (€8.99, or 3 reports for €19.99) tells you why, on eight pages: what makes up the price, ten comparable sales nearby, the risks to check before buying, the neighbourhood, and the rent and yield. See a sample report.
Frequently asked questions
Is the estimate really free?
Yes. The estimate with its likely range is free and needs no registration. Only the PDF report (€8.99) is paid: it explains what makes up the price and shows comparable sales, the risks to check before buying, and the rent and yield.
How accurate is the estimate?
On sales the model did not see while learning, the typical gap between the estimate and the price actually paid was 12.2%, and 10.5% in Ljubljana. 72.4% of estimates were within ±20% of the price. That is why the estimate always shows a likely range, not just one number.
Can I use the estimate for a mortgage?
No. For a mortgage, the bank requires a certified valuation by a valuer working to the international valuation standards. The VERICITY estimate is for information and does not replace a valuation, but it gives you a good idea of the value to expect.
Why is the price in an ad higher than the estimate?
Ads show the price the seller hopes to get. The estimate is based on the prices in sale contracts, so on what buyers actually paid. The difference is normal and often leaves room for negotiation.
Is everything available in English?
Yes. Building and apartment pages, prices by municipality and the PDF report are all available in English. Official sources such as the GURS viewers are in Slovenian.
