Tournai property market: prices, rents and yields in 2026

Apartments for sale in Tournai averaged €2,161/m² in asking price in Q3 2026 (CASAFARI Area Insights, location id 543419, asking prices from indexed listings, outliers excluded), down 1.5% from Q3 2025 and 4.7% below the Q2 2025 peak of €2,267.6/m². Meanwhile, asking rents reached €11.1/m² per month (+7.8% year on year), giving an indicative gross yield of 6.2%, high for Belgium. After Wallonia cut registration duty on a sole home to 3% in January 2025, prices jumped, and the market is now digesting that surge.

Consider a couple from Lille looking for more space. They discover that the budget required for a one-bedroom flat in Wazemmes buys a generous apartment or a brick terraced house with a garden ten kilometres across the Belgian border, while the morning TER train back to Lille Flandres takes just 26 minutes. Once at the notary's office, the real arithmetic begins: €2,161/m² is the starting point on the listings, and Walloon property rules decide the final outlay.

What does an apartment cost in Tournai?

In Q3 2026, the average asking price for an apartment in Tournai stood at €2,161/m², according to CASAFARI Area Insights (location id 543419). It is important to note that these figures track asking prices from indexed listings with outliers excluded, not final notarial deeds. At that average, a standard 75 m² two-bedroom flat near the Scheldt quays or the station district asks roughly €162,000.

Official deed records sit remarkably close to what sellers are asking. According to Statbel's house price figures for the first semester of 2026, the median transaction price for an apartment in the municipality of Tournai was €170,000 across 101 recorded sales in H1 2026. That places Tournai among the least expensive Walloon municipalities for apartments.

To put those numbers into broader context (see our Belgium area guide for national benchmarks), the Belgian median apartment sold for €257,000 in H1 2026, while the regional Walloon apartment median stood at €195,000 in Q1 2026 (+2.6% year on year). For houses, which in Tournai mostly means traditional terraced brick dwellings, Statbel's H1 2026 regional medians for Wallonia were €195,000 for attached or semi-detached houses and €331,000 for detached homes (against €285,000 and €402,400 across Belgium as a whole).

Where is Tournai, and who is actually buying there?

Tournai is a mid-sized Walloon city of 69,066 inhabitants as of 1 January 2026, according to Statbel population statistics. Set on the River Scheldt in the province of Hainaut, it sits 10 km from the French border and about 25 km by road from Lille, forming one of the three corners of the cross-border Eurometropolis Lille–Kortrijk–Tournai.

Rail connections anchor its appeal for commuters. According to the Tournai–Lille train timetable on SNCF Connect in 2026, direct TER trains reach Lille Flandres in 26 to 30 minutes. Heading north-east, Brussels lies about 89 km away, or roughly an hour by InterCity train. Within the city itself, life revolves around a compact historic core — home to the UNESCO-listed cathedral and belfry and the Grand-Place — alongside recently renewed Scheldt quays and an upgraded station district.

Buyers here are overwhelmingly domestic households purchasing a primary residence, alongside a visible minority of French households from the Lille metropolitan area crossing the border for space and lower prices per square metre. There is no holiday or second-home market to speak of. For an international buyer or adviser, Tournai is strictly a value and yield proposition.

Why did prices peak in 2025 and drift down since?

To understand Tournai's price chart over the past three years, you have to look at Wallonia's tax calendar. On 1 January 2025, the Walloon Region cut registration duty (droits d'enregistrement) on an own and sole home (habitation propre et unique) from 12.5% to 3%. First-time buyers and local households rushed to sign deeds. Across Wallonie picarde (the arrondissements of Tournai, Ath and Mouscron), total property transactions jumped by 16.3% in 2025, with the regional median house price reaching €220,000 (+14.3%), the apartment median €181,750 (+6.9%), and Tournai's own apartment median rising 14.2% over the year, according to Fednot's 2025 figures for Wallonie picarde reported by L'Avenir (in French).

In CASAFARI's Area Insights series in this guide — which tracks asking prices on listings, not transaction prices — Tournai apartments climbed steadily from €2,012.2/m² in Q1 2023 to €2,215.6/m² in Q4 2024, dipped briefly to €2,126.8/m² in Q1 2025, and then hit a series peak of €2,267.6/m² in Q2 2025 right after the tax cut took effect. Since that crest, sellers' expectations have cooled:

• Q3 2025: €2,193.2/m²
• Q4 2025: €2,207.5/m²
• Q1 2026: €2,219.8/m²
• Q2 2026: €2,208.2/m²
• Q3 2026: €2,161.0/m²

At €2,161/m² in Q3 2026, asking prices sit 4.7% below the Q2 2025 peak and 1.5% below Q3 2025, though they remain 7.4% higher than in Q1 2023.

Official deed indices show a similar deceleration, though without turning negative. The Statbel residential property price index by region for existing dwellings in Wallonia (base 2025 = 100) recorded year-on-year growth of +5.4% in Q1 2025, +6.7% in Q2 2025, +5.0% in Q3 2025, and +7.0% in Q4 2025, before slowing to +4.7% in Q1 2026 and +3.0% in Q2 2026 (when Belgium overall stood at +3.9%).

Comparing Tournai's quarterly year-on-year asking price changes (Q1 2025 -1.0%, Q2 2025 +4.3%, Q3 2025 +0.1%, Q4 2025 -0.4%, Q1 2026 +4.4%, Q2 2026 -2.6%, Q3 2026 -1.5%) against that smoother regional index highlights a rule of thumb for mid-sized cities: listing prices in a single municipality are noisy from quarter to quarter, and asking prices reacted faster to the post-tax-cut digestion than completed deeds. Readers comparing broader property market trends across Europe will recognise this pattern whenever a fiscal incentive pulls demand forward.

What do rents and yields look like for an investor?

While sale asking prices plateaued after mid-2025, rents in Tournai kept climbing. In CASAFARI Area Insights (asking rents from indexed listings, outliers excluded, not signed leases), the average asking rent for an apartment rose from €9.9/m² per month in Q1 2024 to €10.3/m² in Q3 2025, and reached €11.1/m² in Q3 2026. That represents a 7.8% increase year on year and a 12.1% gain since Q1 2024.

Putting the two series together gives a clear view of why small private landlords look at Hainaut. Dividing the annualised asking rent by the average asking price (12 × €11.1 ÷ €2,161) produces an indicative gross rental yield of 6.2% in Q3 2026, up from 5.6% in Q3 2025 (12 × €10.3 ÷ €2,193.2) and 5.5% in Q1 2024 (12 × €9.9 ÷ €2,148.2). That is noticeably higher than what an investor will find in the Brussels guide or in Brabant wallon.

Steady tenant demand underpins those rents. Tournai hosts higher-education campuses — including UCLouvain's LOCI architecture faculty and HELHa — alongside large hospitals, public-sector employers and local households who remain in the rental market. However, 6.2% is an indicative gross figure calculated on averages before transaction taxes, notary fees, vacancy, maintenance and personal taxation.

Crucially, buy-to-let investors do not qualify for Wallonia's 3% registration duty; they pay the standard 12.5% rate. On a median €170,000 apartment, an owner-occupier pays €5,100 in registration duty, whereas an investor pays €21,250 — a €16,150 difference before notary fees that trims the net yield.

Which Walloon taxes and rules decide the real cost?

Belgium places no restrictions on foreign buyers: both EU and non-EU nationals can purchase residential property freely, with no permit required and no residence-by-investment scheme attached. Once buyer and seller sign the binding preliminary contract (compromis de vente), a Belgian notary verifies title and collects the regional taxes at the final deed.

Buyer or property profile	Applicable tax rate in Wallonia (2026)	Key conditions and notes
Own and sole home (habitation propre et unique)	3% registration duty	In force for deeds signed from 1 January 2025 (Walloon decree of 5 December 2024, SPF Finances circular 2025/C/42). Buyer must not hold another dwelling in full ownership (or must sell it within three years) and must register their domicile there within three years.
Buy-to-let investor or second home	12.5% registration duty	Standard Walloon rate on existing residential property when the 3% sole-home conditions are not met.
New-build property	21% VAT (TVA)	Federal rule applied to the construction value instead of registration duty.

For a detailed breakdown of the 2025 reform, see Wallonia's 3% registration duty explained (in French) on the official regional portal.

Beyond transfer taxes, energy performance is the single biggest line item to watch. An energy performance certificate (certificat PEB) is mandatory in every Walloon sale or letting advertisement. Because much of Tournai's centre consists of pre-1945 brick buildings with weak thermal insulation, buyers should budget carefully for roof, window and heating upgrades. If you plan to let the property, ask your notary or agent to confirm the current Walloon rules on rent indexation for lower PEB classes, as well as the prior declaration required by the Commissariat général au Tourisme if you intend to offer short-term tourist accommodation.

What are the risks in Tournai right now?

Every high-yield regional city carries trade-offs that a careful buyer should weigh before signing a compromis:

• Post-incentive digestion: Asking prices for apartments are already 4.7% below their Q2 2025 peak, and Statbel's Walloon price index slowed from +7.0% in Q4 2025 to +3.0% in Q2 2026. A market driven by first-time buyers and small landlords is also sensitive to mortgage costs.
• Thin quarterly volumes: Statbel recorded 101 apartment transactions in Tournai across the whole first half of 2026 (and only publishes municipal medians when sales exceed 16). In a market of that size, a single new development or a handful of refurbished flats can swing a single quarter's average.
• Asking vs transaction gap: The CASAFARI Area Insights series in this guide tracks asking prices on listings, not notarial deeds. When a market slows down, the negotiation discount between the advertised price and the signed deed often widens.
• Modest demographic growth: Tournai's population of 69,066 on 1 January 2026 grew by only about 0.8% between 2020 and 2026, so long-term organic housing demand grows more slowly here than in faster-expanding neighbours.
• Renovation capex: Buying an older flat at €2,161/m² with a poor PEB rating can require significant capital expenditure to keep the property attractive and compliant for tenants.
