Property with a price significantly higher than the standard land value

In the meantime, I have received an excerpt from the land register. The property is registered there at €150,000 as of 30.01.2018. That is actually quite close to [Grundstücksgröße] * BRW (800 * 190 = 152,000). So it would be a price increase of €100 / m2, thus 52% in just 17 months. Uff...

Well, with us the standard land value has also increased by about 2.5 times since the purchase almost 4 years ago. I think this is currently the case in all desirable locations.

The land register only states the amount for which a security has been established for a loan. It is therefore quite possible that, for example, a certain proportion of equity has been paid, so that the price increase is lower. Overall, however, the market is actually going crazy…

According to the land register, there is a current loan of up to €150,000, for which the seller would also have to pay a prepayment penalty. Without a price surcharge, the seller would even come out of the matter at a loss.

In case anyone wants to know how it continued: the price is obviously so high because the seller still wants to make a good profit despite the speculation tax. Ok, that's just how it is. We actually still want it anyway.

PROBLEM with the story: the seller would prefer the buyer to give him 50-60k€ under the table so that he has to pay hardly any tax. He has already paid property tax, and we would again, so something has to be done about it. So he probably isn't selling to us yet (or "he's thinking it over") but is waiting until someone agrees to his shady deal.

I should have actually suspected it. He already talked in the first conversation about how you could “save” if he made it 20-30 cheaper for the notary. But it sounded more like a bad suggestion than a fixed requirement...

Man is very reckless. If you were to do what he wants, and he expects, say, 160 thousand for the property, but the purchase contract states 100 thousand, then you pay 100 and the title is transferred. Whether the remaining 60 is paid in cash, he would be completely dependent on your swindler's honor. He has nothing in hand. Nothing. He cannot report you for fraud, because he wants illegal money. He cannot prevent the transfer. How? He can basically only send his Russian friends to visit you, who will ask again what is going on with the remaining 60.
