I honestly don’t. If I change my repayment from the current just under 3.5% to 1%, the duration for the complete repayment increases to 70 years. Then I would be 110. A bank must reject that as unrealistic, unless the borrower is really in financial distress and needs to reduce the installment for a certain period for that reason.
And honestly, I don’t understand the problem there either. Our capital service is designed so that we could also manage it with a pension. The bank still has the registered mortgage as security, and if the borrower dies before full repayment, the house, with all rights and obligations, passes to the heirs.
By the way: Auto Europa Bank grants car financing to 80-year-olds with a 60-month term.
