Garage price in the purchase contract from the notary is lower

Then the contract must be changed, resent, and the notary appointment made 14 days later. Right?

We simply received the contract by email. That's enough. Then no postal route needs to be awaited.

In my opinion, this is also a correction (not a change) that does not require a new deadline. If both parties are present, in my opinion, this can also be done directly at the notary.

OK, we'll discuss it then with the notary. Don't want the developer to get angry.

Well, if he can't do the math, he messed it up himself, or the notary assistant.... No one is stopping you from telling the developer already. He has also received a copy.

Am I more at an advantage or at a disadvantage?
