Belgian Housing in Flux: Knokke Drops, National Trends Shift

Belgium’s real estate market is undergoing notable shifts on two fronts. In the exclusive coastal town of Knokke-Heist, summer overcrowding and nuisance from day-trippers are driving some luxury buyers to neighboring Nieuwpoort, while the national real estate barometer shows a slight quarterly decline in housing prices across the country — though experts attribute this to compositional factors rather than a structural downturn.

The Knokke Exodus

Knokke-Heist, Belgium’s most prestigious coastal municipality, has long been the destination of choice for wealthy buyers seeking luxury villas and high-end boutiques. But on hot summer days, the town of 20,000 swells with thousands of tourists from Brussels and Northern France, bringing noise pollution, littering, and a spike in crime. According to HLN, crime statistics show 3,335 crimes recorded last year — 250 more than two years prior — with drug-related incidents up nearly 50%.

Real estate agents in Knokke are divided on the impact. An Willemyns, whose family business spans five generations, told HLN: “Historically, prices continue to rise. During the corona period we had an absolute peak, followed by a very slight correction. Today the curves are climbing steadily again.” Her agency recently handled the most expensive sale in five years: a property worth €25 million.

But agents in neighboring towns tell a different story. Olivier Platteau, a luxury real estate agent in Nieuwpoort, said: “I literally hear from buyers that they sold their property in Knokke and are now looking in Nieuwpoort, purely because of the problems during busy weekends.” Olivier Fleerackers of Flebo Vastgoed in De Haan went further, admitting he sold his own Knokke vacation home due to the nuisance. “The Knokke market is suffering from this, and other coastal towns are indirectly benefiting.”

Nieuwpoort’s Boom

The shift is reflected in the numbers. Nieuwpoort saw prices rise 10.2% in the past year — the highest of any Belgian coastal town — with an average price of €5,236 per square meter. The One Beach complex sold for over €20 million. Still, Knokke remains Belgium’s most expensive coastal municipality at €6,612 per square meter, and international luxury brands continue to open their third Belgian boutique there, after Brussels and Antwerp.

National Market: A Logical Decline

Meanwhile, the national real estate barometer from the notaries’ association shows a modest decline. As reported by HLN, the average house price in Q2 2026 fell to €356,774 (down €3,191, less than 1%), while the average apartment dropped to €286,183 (down €2,067, also less than 1%). Declines occurred in every region except Brussels houses.

Sales volumes are also down, with a national decline of 1.6% and a sharper 2.9% drop in Flanders. Notary Bart van Opstal noted: “Rising interest rates on mortgage loans have certainly played a role.”

The “Compositional” Explanation

HLN real estate expert Bjorn Cocquyt offered a nuanced interpretation: “This is striking news, but there’s a logical explanation.” The price decline is largely compositional — young buyers aged 18 to 35 now represent 44% of the market, and they purchase cheaper properties, pulling the average down. Rising mortgage rates are pushing them to buy now rather than wait, fearing further rate increases.

Investor behavior is also shifting. With stock markets — particularly AI-linked stocks — performing strongly, investors are favoring equities over real estate. Van Opstal noted: “Only when a correction occurs will they shift money toward real estate.”

Year-on-Year Still Positive

Despite the quarterly dip, the year-on-year picture remains positive. Comparing H1 2025 to H1 2026, house prices rose 1.9% nationally and apartments 1.5%. West Flanders apartments saw an 8.5% increase, driven by renewed demand for second homes at the coast amid international tensions. “People choose certainty close to home,” Van Opstal said.

What to Watch

The Belgian housing market appears to be in a period of cautious adjustment rather than decline. The Knokke-Nieuwpoort dynamic highlights how localized quality-of-life issues can reshape micro-markets, while the national trend reflects broader macroeconomic forces — rising interest rates, shifting investor preferences, and changing demographics. If ECB rates stabilize, experts expect the market to recover. But continued stock market outperformance could keep investors away from real estate, prolonging the current hesitancy.

For now, the message from experts is clear: the headline numbers tell only part of the story. The underlying fundamentals remain sound, and Belgium’s housing market is adjusting, not collapsing.
