Somehow, the usual dependencies between construction/purchase costs and loan interest rates simply don't fit right now. In 2001, we paid an interest rate of about 5% for the condominium over 10 years. That was easily affordable since the acquisition costs of the apartment were within a manageable range compared to the salary. Back then, for example, the property transfer tax in NRW was 3.5% (I believe). Now they're finally addressing that. For years, it was said: retirement provision through property ownership, then it was stocks, so what now? What can one still afford to save something for retirement?
