Fifteen years in the Knokke property market: the evolution

The flat market in Knokke-Heist has experienced strong growth over the past fifteen years, both in terms of sales volumes and property prices. The luxury segment in particular stands out, with value rising by up to 84 per cent, whilst the mid-market has also recorded solid growth. Find out how the property market has evolved since 2010 and why quality and prime locations continue to make all the difference.

Fifteen years of Knokke-Heist in figures – how the flat market has evolved

A market that is growing in the long term
When we look at the number of sales per quarter between 2010 and 2025, one trend immediately stands out: the market is more active today than it used to be. In 2010, an average of 650 flats changed hands each year. In the period 2017–2019, that figure was already around a thousand, with a marked peak during the Covid years of 2020–2021. Record volumes were reached then, with over 1,500 transactions in 2021. The pandemic, low interest rates, a number of major construction projects (Duinenwater) and the rediscovery of coastal living all combined to create an exceptional surge in buying activity.

After that peak, the market returned to equilibrium. Between 2022 and 2024, the market stabilised at an average of 970 sales per year. That is lower than the peak year of 2021, but still around 20 per cent higher than the average for the previous decade. In other words: even though the pressure has eased somewhat, Knokke remains one of the country’s most dynamic property markets.

Anyone who has owned a flat in Knokke-Heist for some time can look back on fifteen years of remarkable growth. Since 2010, not only have prices risen sharply, but the number of transactions has also increased steadily. The market has experienced cycles of recovery, euphoria and normalisation, but the end result is clear: in a decade and a half, Knokke has firmly established itself as Belgium’s most resilient coastal municipality.

Rise in value across every segment
Even more interesting than the number of sales, of course, is the question of how prices themselves have evolved. To answer this, we look at the market’s percentiles: the 25th, 50th, 75th and 90th percentiles provide a picture of the lower-priced, average, higher-priced and top segments of the Knokke flat market, respectively.

Between 2010 and 2024, all segments saw a clear rise in value. The bottom quarter (P25) rose by around 59 per cent, the median (P50) by 62 per cent, and the upper middle class (P75) by 58 per cent. The real standout, however, is the top segment (P90), which rose by no less than 84 per cent over the same period. In real terms, this translates to an annual increase in value of 3 to 3.5 per cent for the mid-market and more than 4 per cent per year for the luxury market. Over the same 15-year period, total inflation stood at around 35 per cent.

This gap says a great deal about the nature of property demand in Knokke. Whilst the entry-level and mid-market segments respond primarily to traditional factors such as interest rates, family formation and return on investment, the top end of the market is driven by scarcity and lifestyle. Apartments with sea views, spacious terraces, high-quality finishes or a location in iconic buildings enjoy a level of demand that shows little sign of abating, even in periods of economic uncertainty.

A distinct luxury segment
The faster growth in the highest price bracket is no coincidence. Over the past fifteen years, Knokke-Heist has evolved from a seaside resort into a prime investment and residential market. Whereas it used to be mainly about second homes, today we are seeing more and more buyers who use their flats intensively or live there permanently. At the same time, the number of prime locations has remained limited: sea views, south-facing terraces or exceptional penthouses remain scarce. This combination of limited availability and international demand is driving prices in the higher segment up further year on year.

In practical terms, this means that for owners, the capital appreciation on a prime location – such as the Zeedijk, Albertplein or Rubensplein – has, on average, grown almost twice as fast as the rest of the market over the past fifteen years. Even within the same building, differences can arise depending on orientation, floor level or standard of finish.

The mid-market remains solid
That said, the wider market has also delivered a good return. Anyone who purchased a standard two-bedroom flat without a sea view in 2010 saw its value rise by over sixty per cent on average. That equates to an annual capital appreciation of just over three per cent, excluding any rental income. Combined with good maintenance and limited vacancy rates, this is still a particularly solid result compared with other investments.

It is also striking how stable the Knokke market remains. Even during periods of rising interest rates and stricter lending standards, prices held up well. The market rarely corrects sharply; at worst, growth slows temporarily and there are fewer transactions.

What does the future hold? The fundamentals of the Knokke market remain strong: limited supply, a public with strong purchasing power and a reputation for quality. New-build projects are being finished to an increasingly high standard, with an emphasis on sustainability and comfort, which further underpins the average price structure. At the same time, the market will become more selective: buyers are comparing properties more critically, and flats that do not meet contemporary expectations – such as small terraces, outdated technology or a lack of unobstructed views – will appreciate more slowly in value.

For owners, therefore, the message is twofold. On the one hand, history shows that property in Knokke-Heist has remained a reliable and profitable investment, with long-term growth clearly outpacing inflation. On the other hand, it pays to continue investing in quality: renovations, energy efficiency improvements and aesthetic enhancements ensure that an apartment remains attractive in a demanding market.

Quality pays off in Knokke
Fifteen years of market data demonstrate this beyond doubt: Knokke-Heist is a stable and resilient property market that has seen value increase across the board. The top end of the market, the luxury segment, grew the fastest, but the mid-market also saw a steady and healthy rise in value. Anyone who owns property there today can rightly say that their investment has more than retained its value. And anyone considering selling or reinvesting knows that Knokke remains a market where quality is rewarded.
