Durbuy and the Ardennes property market: prices, buyers and the second-home tax
Asking prices, buyer origins and the second-home tax, with sourced numbers.
Houses for sale in Durbuy and La Roche-en-Ardenne average €2,001.9 per square metre in asking price in Q3 2026 (CASAFARI Area Insights, two municipalities combined, asking prices from listings rather than transactions), up 0.4% year on year and 8.7% below the Q3 2024 peak. In actual sales, the notary federation Fednot records a median house transaction price of €254,500 in Durbuy for H1 2026. For second-home buyers in this inland river-and-forest resort market, Wallonia's 3% registration duty applies only to a sole primary residence; second homes pay 12.5%.
Picture a couple from Ghent or Maastricht standing on the terrace of a limestone cottage above Bomal on a Saturday in October. The Ourthe valley mist is clearing below, and they have two numbers from their adviser in mind: the asking price per square metre and the 12.5% tax that will be added at the notary's desk.
What does a house in Durbuy or La Roche-en-Ardenne cost per square metre?
In Q3 2026, the average asking price for a house across Durbuy and La Roche-en-Ardenne stands at €2,001.9/m², according to CASAFARI Area Insights (queried 23 October 2026). That figure is 0.4% higher than in Q3 2025 (€1,994.7/m²) and 4.4% above Q1 2023 (€1,917.7/m²), though it sits 8.7% below the peak of €2,192.1/m² recorded in Q3 2024.
This series tracks asking prices from indexed property listings with outliers excluded, combining the two municipality location IDs (543744 and 543754) because no single Ardennes-wide location ID exists; it measures what sellers ask, not what buyers ultimately pay at the deed. To put those figures on a human scale, a 150 m² renovated stone house priced at the €2,001.9/m² average comes to roughly €300,000 before transaction costs. As an illustrative example, a buyer purchasing that house as a second home at the standard 12.5% Walloon registration duty adds €37,500 in tax before notary fees.
Where are Durbuy and the Ardennes, and why does that matter for buyers?
Durbuy and La Roche-en-Ardenne are neighbouring municipalities in the Ourthe valley, within the Walloon province of Luxembourg. Despite its tourist fame, the area is lightly populated: on 1 January 2026, the IWEPS WalStat population sheet for Durbuy (in French) counted 11,364 residents across 157.1 km² (72.3 inhabitants/km², average age 45.1), while the IWEPS WalStat population sheet for La Roche-en-Ardenne (in French) recorded 4,055 residents across 148.5 km² (27.3 inhabitants/km², average age 45.4), for a combined population of 15,419.
Each municipality brings together distinct micro-markets: Durbuy has its cobbled historic centre, Barvaux as the practical commercial hub, the river confluence at Bomal, and quiet stone hamlets such as Villers-Sainte-Gertrude; further upstream, La Roche-en-Ardenne gathers around its feudal castle and wooded slopes.
Driving distances explain the buyer mix. The valley lies under an hour south of Liège (see the Liège area guide) and around two hours by car from Brussels (see the Brussels area guide), Antwerp, Ghent, and the southern Netherlands. Unlike the Belgian coast, where high-density seafront flats dominate, this is an inland river-and-forest market built around kayaks, woodland trails, stone village houses, timber chalets and gîtes.
Are Ardennes property prices rising or falling in 2026?
On the listing side, the rapid run-up of 2024—when house asking prices in Durbuy and La Roche-en-Ardenne climbed to €2,192.1/m² in Q3 2024—has partly unwound. Over the four quarters from Q4 2025 to Q3 2026, average asking prices in CASAFARI Area Insights have held within a narrow band between €2,001.9/m² and €2,072.4/m², pointing to a stable plateau rather than a slide.
Notary deed records tell a complementary story of normalisation after a fiscal surge. According to Fednot's Baromètre des Ardennes for H1 2026 (in French), published on 16 September 2026 across 25 Ardennes municipalities, residential sales volume dipped by 1.5% in H1 2026 compared with H1 2025 (against −0.1% across Wallonia), following a 15.4% jump in H1 2025. The median house transaction price across the 25 Ardennes municipalities reached €220,000 in H1 2026, up 1.4% on 2025 (€217,000), after jumping 14.2% between 2024 (€190,000) and 2025. Why was 2025 so strong? Wallonia cut its registration duty for sole primary residences to 3% on 1 January 2025, pulling primary-residence buyers forward across the region.
Durbuy itself stood out from the wider Ardennes slowdown. As noted in Fednot's barometer and La Libre's report on the 2026 Ardennes barometer (in French), the median house transaction price in Durbuy rose 10.7% in H1 2026 to €254,500 (up from €230,000 in 2025). That puts Durbuy well above the Walloon median of €233,000 in H1 2026 and second only to Ciney (€285,000) among the municipalities analysed.

Who is buying in Durbuy and La Roche-en-Ardenne?
In H1 2026, Fednot's Baromètre des Ardennes shows that 77.4% of house buyers across the 25 Ardennes municipalities lived in Wallonia (and 47.4% already lived in one of those 25 municipalities), 16.6% came from Flanders (up from 15.1% in H1 2025), 3.6% from Brussels, and 2.5% from abroad. In Durbuy specifically, Flemish buyers accounted for 26.1% of house purchases in H1 2026, up from 20.4% in H1 2025; in La Roche-en-Ardenne, the Flemish share stood at 22.7% in H1 2025 (Fednot). Only Vresse-sur-Semois (58.3%), Houffalize (40.5%) and Erezée (33.3%) recorded higher shares of Flemish buyers in H1 2026.
The average buyer in the Ardennes is 43 years old, compared with 39 across Belgium as a whole (Fednot, H1 2026). For an international buyer from the Netherlands, Luxembourg or further afield, the takeaway is straightforward: while non-resident foreign buyers represent 2.5% of the market, your real competition at viewings is equity-rich Flemish households in their forties and fifties.
Three distinct buyer groups shape the valley: local Walloon households buying a primary residence around hubs like Barvaux; Flemish and Brussels second-home buyers seeking stone houses or chalets in quieter hamlets; and private gîte investors. Institutional landlords are almost entirely absent.
What taxes and rules apply to a second home in Wallonia?
The decisive budget rule in Wallonia is the registration duty (droits d'enregistrement). Under the Walloon decree of 5 December 2024, explained in the Walloon government's note on the 3% registration duty (in French), the reduced 3% rate in force since 1 January 2025 applies strictly to a buyer's sole, owner-occupied primary home (habitation propre et unique), with no cadastral-income ceiling and three years to sell an existing main residence. Second homes, holiday chalets, gîtes and rental investments do not qualify; as Fednot explicitly notes for the Ardennes, they pay the standard 12.5% rate. For broader context on how regional duties compare across the country, see our Belgium area guide.
Beyond the transfer tax, buyers and their advisers should check three practical points before making an offer:
- Energy performance: Much of the valley's housing stock consists of older stone properties with weak energy (PEB) ratings. Wallonia does not currently impose a mandatory renovation deadline like Flanders, but banks and resale buyers increasingly price renovation costs into their offers.
- River flood zones: After the July 2021 floods along the Ourthe valley, checking the official Walloon flood-hazard maps is essential before bidding on any waterside house in La Roche-en-Ardenne, Bomal or Durbuy.
- Accurate pricing: Because asking prices vary sharply between Durbuy's historic centre and outlying villages, buyers and agents use valuations, Comparables and market studies (with technical details in the Comparables and valuation documentation on developers.casafari.com) to benchmark a listing against recent local stock.
What about apartments, and how reliable are the numbers?
In Q3 2026, apartments for sale in Durbuy and La Roche-en-Ardenne show an average asking price of €2,020.1/m² in CASAFARI Area Insights, up 7.7% on Q3 2025 (€1,876.5/m²) and 1.3% above Q1 2023 (€1,993.4/m²). Treat that percentage change with caution: between Q4 2024 (€1,704.9/m²) and Q2 2025 (€2,299.7/m²), the apartment series swung by 34.9% in just two quarters. Because flats make up a tiny fraction of the Ourthe valley housing stock, a handful of new or refurbished listings moves the quarterly average.
When working with these numbers, keep four methodological points in mind:
- The CASAFARI series combines Durbuy (543744) and La Roche-en-Ardenne (543754) as a two-municipality proxy.
- The CASAFARI Area Insights figures in this guide measure asking prices per square metre from active listings, not notarised transaction prices.
- No rental series is tracked for these two municipalities, so we do not publish an indicative gross rental yield.
- Micro-locations differ markedly between tourist centres and rural hamlets.
Buyers' agents scanning the valley for stone houses and chalets can search across fragmented portal listings using Property Sourcing across the whole Ardennes listing stock, or compare regional shifts on the wider Belgian property market trends page. Analysts and developers who wish to reproduce these quarterly time series can inspect the API query in the Area Insights documentation on developers.casafari.com, or query the data directly inside an AI assistant via Casafari MCP for analysts working in an AI assistant. API and MCP calls consume tokens according to your plan.

Frequently asked questions
How much does a house in Durbuy cost in 2026?
Two different measures give the clearest picture. On the listing side, CASAFARI Area Insights puts the average asking price for houses across Durbuy and La Roche-en-Ardenne combined at €2,001.9/m² in Q3 2026. On the deed side, Fednot's transaction median for a house in Durbuy alone was €254,500 in H1 2026, up 10.7% on 2025. Keep in mind that asking prices and final notarised transaction prices are not the same thing, and that properties in Durbuy's historic centre command higher prices than houses in outlying villages.
Can a foreigner or non-resident buy a second home in the Belgian Ardennes?
Yes, non-resident and international buyers regularly purchase second homes in the Ardennes; in H1 2026, buyers living outside Belgium accounted for 2.5% of house transactions across the 25 Ardennes municipalities in Fednot's barometer, alongside 16.6% from Flanders and 3.6% from Brussels. Every purchase is completed by deed before a Belgian notary. The essential line item to budget for from the start is the 12.5% Walloon registration duty that applies to any purchase that is not your sole primary residence, on top of notary fees.
Does the 3% Walloon registration duty apply to a second home?
No. Under the Walloon decree of 5 December 2024, in force since 1 January 2025, the 3% registration duty applies only to a buyer's sole, owner-occupied primary residence. As Fednot explicitly notes for the Ardennes, a holiday home, gîte or investment property pays the standard 12.5% rate. As an illustrative example on a €300,000 purchase, registration duty comes to €37,500 at the 12.5% second-home rate compared with €9,000 at the 3% primary-residence rate.
Are Ardennes property prices going up or down?
House asking prices in Durbuy and La Roche-en-Ardenne have plateaued: in Q3 2026 they averaged €2,001.9/m² in CASAFARI Area Insights, up 0.4% year on year and 8.7% below the Q3 2024 peak of €2,192.1/m². Notary transaction data from Fednot confirm a wider normalisation in H1 2026, with Ardennes house sales down 1.5% and the regional median price up 1.4% to €220,000 after a 15.4% volume surge and 14.2% price jump in 2025. Durbuy itself bucked the wider slowdown in H1 2026, with its median house transaction price rising 10.7% to €254,500.
Why do so many Flemish buyers choose Durbuy and the Ardennes?
Driving time and relative affordability are the two main reasons: the Ourthe valley is around two hours from Ghent, Antwerp and Brussels, while median house transaction prices of €254,500 in Durbuy and €220,000 across the Ardennes (Fednot, H1 2026) remain well below levels on the Belgian coast and in Flemish Brabant. Fednot records that 26.1% of house buyers in Durbuy in H1 2026 came from Flanders (up from 20.4% in H1 2025), and 16.6% across the 25 Ardennes municipalities. With an average Ardennes buyer age of 43 compared with 39 nationally, these are largely equity-rich households buying stone houses and chalets in quiet hamlets.
Is a gîte in Durbuy a good investment?
Durbuy and La Roche-en-Ardenne benefit from year-round outdoor and family tourism, which supports steady visitor demand, but buyers face established local competition and significant upfront costs. Any gîte or holiday-let purchase incurs the 12.5% Walloon registration duty rather than the 3% primary-home rate, alongside energy and renovation work on older stone buildings. Because CASAFARI does not track a rental series for Durbuy and La Roche-en-Ardenne, we do not quote an indicative yield; prospective investors should benchmark purchase prices with Comparables and track quarterly supply and asking prices in Area Insights.
