Just wait for the bubble to burst.. No price increase since 2007.
Why would anything burst? People aren't having a problem making their mortgage payments, and while demand is down, it's still there. Most housing in Poland is owned with no mortgage. Zero. Zilch. I'm guessing those folks that thought luxury apartments would be a good idea are probably screwed right about now...the people building moderately prices houses and flats are doing pretty well.
There is a world recession!
Really? Most economies are doing alright.
