That's the case in NL as well; the causes are multi-fold, housing prices have consistently gone up in the past decade, while mortgage interest rates have gone down, meaning it's more attractive and interesting to get a house and mortgage now and fix the interest rate.

But the other issue there is a housing shortage, because population increase is not slowing down.

But the other issue is that houses aren't being built fast enough, for diverse reasons - NIMBY, having to give up farmland or nature for houses, counties that want pretty housing estates instead of functional apartment buildings (because 'ugly' houses attract undesireables), and new nitrogen laws making getting licenses more difficult.

And now there's sudden inflation due to a sudden change in situation (to put it mildly), which triggered the EU to rapidly increase interest rates (I'm no economist, I'm not sure how the two are related), which triggered mortgage rates to increase.

Given people were already borrowing the max amount they could, if the interest rates suddenly go up, a gap appears which caused the reduction in interest in buying a house, lowering demand. The other one is that people stopped looking for houses because their energy bill suddenly tripled or worse.
