Invoice from private individual to bank?

And theoretically, could you have said: We next need 20,000 euros for the roof, plumbing, and electrical, and they would have transferred it?

Yes, we had our construction account and our bank card for it. With that, we were able to pay.

However, I have to say that we built turnkey with a prefabricated house builder, and the really big invoices came from them. For flooring, painters, kitchen, etc., we did not necessarily have to submit an invoice. For example, we paid for the flooring normally with the EC card from our construction account.

Hello!

You should discuss this important point with your financing bank! Some banks have difficulty paying out a lot of "Muscle Power"!
