Construction on someone else's property with subsequent purchase

Have you ever considered that your acquaintance does not want to sell and is just looking for reasons?

Have you ever considered that your acquaintance doesn't want to sell

Have you ever considered that your good acquaintance might become an enemy, and that the property and the new house would then belong to her, she has already obstructed things once before

We would therefore tear this down, especially since it is also located relatively far back on the property and we would like to build with an appropriate distance (5m) from the street

Have you checked whether this is even possible?

Basically, we would also add the difference on top, but so far our acquaintance has been uncooperative in this regard.

I could rather imagine that she might be hoping to raise the price in a few years? Or she doesn't actually want to sell? If you basically pay the capital gains tax for her, she has zero loss if she sells it to you now, so I don't understand why she is otherwise being so uncooperative.

our acquaintance was contradicted in this regard. But it would of course be the easiest and most sensible option. I will talk to her again about it. We would - if she cannot be persuaded

It seems to me that she doesn’t want to sell at all. That’s just your wish, right?

It would not be possible to regulate this bindingly in the notarial contract already, since the points in time of the notarial certifications are decisive for the calculation of the speculation period.

Wrong! It is not about a purchase contract, but about a notarial purchase offer. This is legally harmless and no speculation tax is incurred (provided the 10 years are observed at the actual purchase or the acceptance of the offer).
