"Approximately 40,000 people are waiting for mortgage refinancing this year. At the current interest rate, their monthly payments can increase by up to 50 percent. This puts us in a situation where many people will be forced to consider whether it would be better to sell the property. This applies in particular to owners of investment flats who have a property encumbered by a mortgage. For investment in real estate to make sense, it must have a return of around 5-6%. This is practically impossible in the current situation," Mejzlík said.
