short-term notary appointment - possible pitfalls

I see two possible problems: For the registration of the land charge, I need the corresponding documents from the bank; let's see if I can get them on such short notice. If these only arrive at the notary later, I would have to pay for a second notary appointment to register the land charge, right?

You as the buyer pay the notary anyway. And if you register the land charge later, the fee for it just accrues later. In total, it doesn't cost more than doing everything in one appointment.

Regarding your own notary... actually, the buyer usually appoints the notary, but what real benefit would there be in choosing one yourself, especially if you don’t know any and thus have no preferences... well. Sometimes there are practical reasons, for example, in our case, the plot came from the city, the contract needed some special clauses, and it somehow made sense to have such a contract drafted once for dozens of land sales. In fact, the notary was also somewhat cheaper for us than the fee calculators suggested beforehand; I guess they had a deal with him (he does the business of his life when he gets to handle an entire large new development).

Thanks again for your tips.

I have now paid the agent (who has already had several interested parties who backed out at the last minute) a discount on the commission, in return for a written agreement that he will not offer it to anyone else until 13.9., and scheduled a notary appointment for 6.9. This should ensure that everything now runs smoothly.

That's good.
