Not just price wise, as in totally flat for years and years, but that there will be a huge surplus of apartments on the market, the only active buyers/renters will be dominated by those in their 20s/30s and therefore will largely be a renters market.
Look, the older generation is dying in droves, few Poles can make it past 75, almost all live in communist blocs or spacious prewar apartments by themselves, one of the benefits of communist 'housing for all'. Most will be inherited and, boom, a substantial part of the population will have their housing taken care of. Why drown in a sea of loans when your grandparents left your family 2 apartments to choose from?
I guess it also goes without saying that most parents that had or will have children at most 2 children, but the single child is predominant. So when those grandparents die and their parents in 20 years, that single child will have anywhere from 3-4 pieces of real estate in their name Not bad.
But thats not even that important, the problem in Poland is that the population peaked in 1995 and has been dropping since, the birth rate is now at a 1:1 ratio with the death rate, but that the birth rate in Poland is dropping like a rock. In 10 years all studies point to the 1:2 ratio at the minimum.
So whats that mean? In 10-15 years, when those who went crazy are only halfway through paying their mortgages at 10k zl/m2, there will be very little demand on property ownership.
I have no idea how this could shape up, but you can see its not looking good. Coupled with the fact that there are very few migrants coming into Poland which did in fact save a few Western european countries, that a lot of Poles want to leave Poland, and that Polish society, culture, and language isnt exactly 'open' and easily accessible, and that government policies on economic growth/poverty reduction/improving quality of life are at best a joke, well...
edit:
Depends on the situation and mortgage currency, do you have a CHF mortgage by any chance?
No, like I said I dont have any real interest in or connections with real estate, no mortgage, just an inherited house.
