Ok... Stress with private health insurance and occupational disability insurance cannot be ruled out. My approach here: repayment only 1% (rate thus about 1100 EUR) and always a reserve for 2-3 years bridging. The actual repayment takes place through special repayments. There's nothing against that, right?
We did it similarly (both freelancers)
2 years interest and repayment + minimal living expenses + insurances were and are kept in an otherwise untouchable account for the worst-case scenario, which we hope will never happen.
In addition, a business interruption insurance covers rent and personnel costs for 1 year.
After that, a decision would have to be made anyway.
Since we are already somewhat older, we repay significantly more, but have in the contract that we can change the installment amount 4 times during the 10-year full repayment period. The bank was initially not enthusiastic about that, but after appropriate explanation it was possible.
If the worst-case scenario does not occur, we have reserves for repairs, which are likely to be necessary for a used property after 10 years.
