I believe that bubble will collapse soon.
Thats the golden question... People in the Polish real estate industry will have us believe that prices can only go up, up and up. I have my reservations.
The speculators have already moved on to access other markets as you have mentioned. The Polish real estate market is only sought after in only 3 parts of Poland.
The answer perhaps may be found in what the average Polish worker earns and current interest rates.
Some people are yet to have there fingers burnt, unfortunately some who make comments on this forum.
Remember the financial cycle?
