Property only after contract with the developer

We signed a declaration at the notary appointment during the purchase of our property stating that it is NOT a linked transaction.

All parties signed there and the notary sends it directly to [Zimmer Finanzamt].

Why should the tax office be interested in you stating that it is not a tied transaction (and also the construction company and the real estate agent)? Somehow, there is obviously a lack of neutrality.

On the contrary, such a declaration practically calls out for an in-depth audit by the [FA]...

On the subject: We are currently also selling a plot of land and several construction companies are now offering it with developer ties and planned houses. They have asked us, but there is no broker contract or anything similar on our part. This is unfortunate for the potential customer because we have nothing to do with the construction companies and do not receive any commission or other compensation for it. However, the tax office is hardly likely to be interested in this, and we will not actively participate in any concealment actions.

Wasn't there someone here before who had quite a bit of trouble with the same starting situation because none of the properties proposed by the construction company were satisfactory?

Funny: hereby we jointly declare that we do not act jointly. Today we came together to confirm that we have not agreed upon anything. And then this obvious false statement is even made virtually under oath in front of the notary. Cooool (find the mistake). *ROTFL*

and we will not actively participate in any concealment actions.

Then go to the notary yourselves and under no circumstances authorize the home seller to represent you there.

There was, you probably mean last November:

But relevant to the topic would also be:

And recently it was also about a replacement plot here – without developer binding, but the OP wants to keep the general contractor for other reasons, and now has to build a “one-and-a-half-story” instead of a city villa:
