Made a literal spreadsheet with every provider, account number and deadline. Sounds excessive, kept me sane through the whole marathon.
I thought getting the keys was the finish line. Then came electricity, water, internet, waste registration, building fees — each with its own account, deposit, and waiting period, half of them needing a local bank account I didn't have yet. It took a month to feel properly moved in. How did you sequence all this without going mad?
