In October of last year, a test case was successfully brought in the European Court by a Polish couple against their Bank over the terms of their Swiss Franc Mortgage. A complicated judgement that essentially denied the banks claim they they alone had the right to set the exchange rates when demanding repayments. This has resulted in a flood of similar claims from all over the country as homeowners received confirmation of what they had always suspected, the Banks were screwing them and they were due recompense.
What a year it's been for both the Polish economy generally and the Polish property market in particular. Growth in the number of new build properties, prices and mortgage approvals all exceeded official forecasts. Unemployment, despite increasing marginally in the last quarter remains at an historic low of 5.1 % and salaries have increased on average by 6% in 2019.
