My partner and I have a joint account on which everything runs. I paid for the construction from my account because I have substantial reserves there and also a decent overdraft facility. This way, I could always pay every bill immediately, even if a payment from the bank took a day. Since I recorded every tiny bill/booking down to the last cent in an Excel sheet, it all matched perfectly in the end. After paying the last invoice, I transferred the last few thousand euros from the construction to the joint account. Since then, the account has been responsible for everything related to the house. Our accounts are not with the financing bank. Account management fees go against my "stingy is cool" mentality when others offer it for free with no real services in return. I have been with Hypo for almost 30 years. Whether the money arrives immediately or two days later at the bank for the monthly installment makes no difference to me. They have SEPA, so they are responsible for getting their money themselves.
