Aalst property market: prices, rents and yields in 2026

The average asking price of an apartment in Aalst reached €2,827.3/m² in Q3 2026, up 11.2% year on year after two and a half flat years (CASAFARI Area Insights, indexed listings, outliers excluded). In official deed data from Statbel, the 2025 median transaction price was €245,000 for an apartment and €305,000 for a house. Asking rents averaged €11.0/m² per month in Q3 2026, giving an indicative gross yield of 4.7% before Flemish registration duty of 2% for a sole own home or 12% for investors, all in a city on the Dender 25 to 30 minutes by train from Brussels.

Where is Aalst, and why do Brussels commuters end up here?

Spend a Saturday morning with a couple working at the European institutions or a northern Brussels business park, freshly outbid on a modest terrace in Dilbeek or a two-bedroom flat in Ghent, and the conversation sooner or later turns westward along the railway line. Twenty-five to thirty minutes on the direct train from Brussels-South—and about half an hour the other way from Ghent—the river Dender bends through Aalst. What the capital's immediate ring prices as a two-bedroom apartment will, here, still buy a three-bedroom terraced house with a garden or a bright flat within walking distance of the station. And for ten consecutive quarters between early 2023 and mid-2025, apartment asking prices in the city barely moved at all, before turning decisively upward over the past five quarters.

Aalst is not a sleepy dormitory town. It is East Flanders' second urban centre, with a municipal population of 93,094 on 1 January 2026 according to Statbel population figures for Aalst, up from 87,978 at the 2021 census and roughly 76,500 in 2001. Beyond its three days of UNESCO-listed Carnival in late winter, its daily economy runs on a large hospital sector—led by the OLV Hospital campus—regional schools, retail, and the logistics and business parks strung along the E40 motorway and the N9 arterial road.

For anyone house-hunting, it helps to know that the municipality of Aalst consists of the historic urban core plus eight surrounding villages absorbed over time: Hofstade, Moorsel, Erembodegem, Nieuwerkerken, Gijzegem, Herdersem, Meldert and Baardegem. They offer two distinct property markets. The centre, along with the redeveloping station quarter and the Dender waterfront around the Tragel and Pierre Corneliskaai, accounts for the bulk of apartment listings and new-build schemes aimed at young commuters and local downsizers. The outer villages are predominantly family house territory, where semi-detached and detached homes with gardens attract buyers trading a slightly longer commute for space.

What does an apartment cost in Aalst?

In Q3 2026 (the quarter starting 1 July 2026, queried on 23 October 2026), the average asking price for an apartment in Aalst was €2,827.3/m², based on listings indexed by Area Insights, where the Aalst series come from (location id 543011, outliers excluded). In practical terms, a standard 85 m² two-bedroom apartment in the municipality carries an average asking price of roughly €240,000.

Official deed records tell a consistent story from a different angle. According to Statbel real estate prices by municipality, province and region, which track signed notarial deeds rather than portal listings and publish medians rather than prices per square metre, the median apartment in Aalst sold for €245,000 in 2025. For houses across the municipality, Statbel's 2025 median stood at €305,000 overall—splitting into roughly €295,000 for terraced and semi-detached houses (gesloten and halfopen bebouwing) and about €449,000 for detached homes (open bebouwing).

Set beside its neighbours, Aalst remains noticeably more affordable. Statbel puts the median apartment transaction price in the province of East Flanders at €262,500 in Q1 2026 (−0.9% year on year), and across the Flemish Region at €265,000 in Q1 2026 (+3.4% year on year) and €269,000 in Q2 2026. Readers comparing commuter options can set these figures against the Brussels guide for the capital's price level and Ghent property prices for comparison, both of which sit substantially higher.

One methodological note is worth keeping in mind whenever you read Belgian market reports: CASAFARI asking prices per square metre and Statbel transaction medians measure two different stages of the market. Asking prices reflect what sellers and developers currently demand on property portals, adjusted for surface area; Statbel medians record the middle deed price actually signed at the notary, regardless of apartment size, several months after a sale is agreed. They complement each other, and should never be compared one-to-one.

Are prices in Aalst going up?

For two and a half years, the honest answer for Aalst apartments was no. In the CASAFARI Area Insights series, average apartment asking prices opened at €2,569.1/m² in Q1 2023 and spent the next ten quarters drifting sideways within a narrow band between €2,507.3/m² (the low point in Q2 2025) and €2,589.1/m². Higher mortgage rates in 2023 and 2024 kept local buyers cautious, and sellers adjusted their expectations in small increments.

Since that Q2 2025 trough, the curve has changed shape. Apartment asking prices in Aalst have risen for five consecutive quarters to reach €2,827.3/m² in Q3 2026. That represents a rise of €285.3/m², or +11.2%, compared with Q3 2025 (€2,542.0/m²), a gain of +12.8% from the Q2 2025 low, and +10.0% across the full series since Q1 2023.

Why the sudden catch-up after ten quiet quarters? Three practical factors stand out in the local market:

• Lower entry tax for owner-occupiers: On 1 January 2025, Flanders cut the registration duty on a sole owner-occupied home from 3% to 2%, immediately improving purchasing power for first-time buyers and local movers.
• Spillover from Brussels and Ghent: As affordability tightened in the capital's periphery and in Ghent, more dual-income commuters widened their search radius along the Dender line.
• New-build composition around the station and river: Ongoing regeneration around Aalst station and the Dender banks brings modern, energy-efficient apartments onto the market at the upper end of local pricing, which naturally lifts the municipal average.

Even so, a measured reading is essential. In the broader Flemish Region, Statbel's Q2 2026 transaction data (published 22 September 2026) show the median house price rising at a steadier +4.6% year on year to €355,691, while the number of houses sold across Flanders fell by 7.2% compared with a year earlier. Aalst's +11.2% figure measures asking prices, not closed deeds; the latest quarter's data can be revised as listings close, and buyers still hold negotiating room on older stock.

What are rents and yields like for a buy-to-let in Aalst?

While sale asking prices paused and then accelerated, the rental market in Aalst has climbed in a quieter, steadier line. In Q3 2026, the average asking rent for an apartment in Aalst reached €11.0/m² per month in CASAFARI Area Insights, up from €10.4/m² in Q3 2025 (+5.8% year on year) and €9.8/m² in Q1 2024 (+12.2% over two and a half years). For a typical 80 m² two-bedroom flat, that equates to an average asking rent of around €880 per month before common charges.

Setting the Q3 2026 average asking rent (€11.0/m² per month, or €132.0/m² per year) against the average asking sale price (€2,827.3/m²) gives an indicative gross rental yield of 4.7% for apartments in Aalst. A year earlier, in Q3 2025, before sale asking prices outpaced rents, the equivalent figure stood at 4.9%; across the series since early 2024 it has hovered between roughly 4.5% and 5.0%.

Tenant demand in Aalst is domestic and stable: young local households saving for a deposit, medical and administrative staff at the OLV Hospital campus, employees of the E40 business parks, and commuters who want to test the train line before buying. Once a tenancy is running, Belgian residential rents are indexed annually to the health index (gezondheidsindex), subject to Flemish rules linking full indexation to the home's energy performance certificate.

For a private investor weighing a buy-to-let apartment—a group for whom we build dedicated CASAFARI tools for property investors—the decisive number is not on the property portal but in the Flemish tax code. Because the 4.7% figure is a gross yield calculated on asking prices before transaction costs, vacancy, maintenance and taxes, you must factor in the 12% standard registration duty that applies to any purchase that is not your sole owner-occupied home. On a €245,000 apartment, 12% duty adds €29,400 to the acquisition cost before notary fees, compared with €4,900 for an owner-occupier paying 2%. In Flanders, it is that ten-percentage-point tax gap, much more than the headline property price, that separates owner-occupier arithmetic from investor arithmetic.

What does a buyer from abroad pay in taxes and need to know?

Belgium places no restrictions on foreign property ownership. Whether you are an EU citizen working in Brussels or a non-EU national buying from abroad, you purchase under the exact same legal and fiscal rules as a Belgian citizen, without permits or quotas. For a full walkthrough of how Belgian conveyancing works across all three regions, see our Belgium property guide for the national rules.

In Aalst, because it lies in East Flanders, Flemish regional property rules apply. Three rules shape every purchase budget in 2026:

1. Flemish registration duty (verkooprecht): Under the Flemish Tax Code, a natural person buying an existing home as their sole, owner-occupied residence (enige en eigen woning) and registering in the population register at that address within the statutory period pays a reduced registration duty of 2% (in force since 1 January 2025; previously 3%). All other purchases of existing residential property—including buy-to-let investments, second homes and purchases through a company—pay the 12% standard rate. New-build properties are generally subject to 21% VAT instead of registration duty. You can test your own scenario on a Flemish registration duty calculator.
2. The announced 2027 change from 2% to 3%: In its Septemberverklaring in September 2026, the Flemish government announced that the reduced rate for a sole owner-occupied home will rise from 2% back to 3% from 1 January 2027. According to a legal note on the announced 3% rate from 2027 and VLABEL's position (VLABEL position no. 26021 of 1 October 2026), it is the date of the signed private sale agreement (compromis), rather than the later notarial deed, that determines whether the 2% rate still applies. On a €250,000 apartment, that one percentage point is the difference between €5,000 and €7,500 in tax. As of 23 October 2026 the decree had not yet been formally enacted, so buyers signing near year-end should confirm the status with their notary.
3. The Flemish renovation obligation (renovatieverplichting): Much of Aalst's inner-ring terraced housing dates from before 1970 and carries high energy use. In Flanders, anyone buying a residential house or apartment with an Energy Performance Certificate (EPC) label E or F must renovate it to reach at least label D. On 1 January 2026 (approved on 12 December 2025), the Flemish government extended the compliance deadline from 5 to 6 years after the notarial deed—including for obligations already running—and dropped the previously planned ratcheting beyond label D, while ending the old EPC label premium on the same date, as set out in the Flemish renovation obligation explained.

The buying process itself follows two binding steps: once an offer is accepted, buyer and seller sign the private sale agreement (compromis), which is legally binding and usually accompanied by a 10% deposit held in the notary's escrow account; the formal deed (authentieke akte) is then signed before a Belgian notary within roughly four months, at which point the balance and registration duties are paid. Finally, note that Aalst is a primary-residence and long-term rental market; short-term tourist letting is marginal here and requires registration under Flemish tourist accommodation rules.

How to reproduce these figures with CASAFARI

Every asking-price and asking-rent figure in this guide is reproducible. In CASAFARI, Location Lookup resolves the municipality of Aalst to location id 543011, and Area Insights aggregates active and historical listings across Belgian portals, deduplicating multi-agency listings and excluding statistical outliers to build clean quarterly series for sale_apartment_psqm and rent_apartment_psqm.

If you are advising a buyer on a specific street in Hofstade or near the Grote Markt, municipal averages are only the starting line. You can run Comparables and market study for a single Aalst listing to benchmark a seller's asking price against comparable properties on the same street or in the same village before submitting an offer, or use Property Sourcing for new and off-market listings to see the full market across agencies in one feed.

For analysts, prop-tech teams and valuation departments who want to pull the Aalst series directly into their own models, the underlying endpoints are documented in the Area Insights documentation on developers.casafari.com and the Comparables and valuation API documentation. API and Casafari MCP calls are metered in tokens.
