Thank you for all your responses!
But we use the equity anyway at the end, so we have it as an intermediate buffer anyway.
We had to provide ours right at the beginning, which I can understand from the bank’s point of view.
I have always transferred smaller amounts from equity this way and when the 5000€ were collected, I commissioned the payout to the construction account and got the money back.
It will probably come down to exactly that for us as well. Sounds easiest if they don’t work with advances.
The kitchen thing could also cause problems
We have a written confirmation from the bank that we can submit the kitchen + inventory at the end as part of the construction financing because there was this misunderstanding about the amount of equity at the beginning.
And something else:
We have a financing amount of 350k.
Assuming we end up needing only 330k.
Does the bank then just pay out the remaining 20k and finance later things (garden, fence, terrace, etc.) with it?
