InWroclaw - you should start looking for a flat at the internet, in sites like : domgratka.pl, gumtree.pl, otodom.pl, domiporta.pl, wspollokator.pl. Otherwise you will be treated like an intruder by agencies who deal mainly with selling new developements or renting commercial space as their main trade.
So yes, there is indeed a big rental market.
Don`t you read the data, the big rental market refers to commercial space only. 98 % of Polish live in commercial rent free dwellings.
Why can`t some people argue for just the sake of it. If some information can be called by some as advantageous for Poland, immediately there is a reply that it can`t be possible.
peterweg is right in his statement .
70 % of Polish live in own houses or flats. The rest, that is, to 29.1 percent of housing dwellings include state or municipal premises belonging to TBS, National Forests, Polish railway which is PKP , Polish army - Wojskowa Agencja Mieszkaniowa , etc., which qualifies as a lease according to Eurostat but at non-market prices. The prices are very small and it can`t be put on the market for obvious reasons because it is connected with the job only. If you join the Polish army you will get for an entire lifetime a state owned flat for some pennies, currently it is 4.70 Zl per square meter a month. So it is easy to calculate, the cost could be 250 Zl a month for 2 bedrooms flat. But it is excluded from the commercial market. Most cooperative apartments are also privately owned called in Poland as Spółdzielnia Mieszkaniowa which is not by all means municipal housing, which is a state owned dwelling which is called TBS. TBS counts for 5 % of the whole market, which is not much. Some foreigners misinterpret those two types TBS with SM - komunalne i spółdzielcze. "Komunalne” means municipal housing, spółdzielcze means owned by cooperative, which a form of private ownership with is given rights of voting and deciding about common property and it management of common spaces like green areas, repair funds.
After filtering the percentage turns out that in terms of a commercial lease it pertains to only 2% of people.
