House purchase foreclosure auction - What price is realistic

I think everything has been said so far. You have set a budget for yourselves to buy an old building. He imagines a higher price because he has invested this and that amount. For you, it does not matter how he arrived at his number; only the fact itself is interesting, namely his price expectation. Now there are two cases. He finds someone else who wants to buy it at the asking price, then the two make their deal and that's it. Or he finds no one, because the property does not actually have the market value. Then you might still have success with your offer.

Based on experiences here, building will probably cost you significantly more than these 200k €, even with a very cheap plot. In return, you get a brand new house that you have planned according to your wishes. However, you have to endure quite a stressful construction phase until you can move in after 1.5 years. If you buy the existing house as it is, you will have a ready-to-move-in and, according to your statement, reasonably renovated house with a few new wallpapers; it costs you less, but you have to accept it as it is (layout, equipment). Only you can personally make the choice between these two options. And only you can set the price from which the advantages of the existing house outweigh for you.

So the value calculated by the land registry office for this property is between 110 and 130k for this region..

Then just buy yourself such a property for 120k. Can't get it? See....!

What the market demands is 200k. If someone pays that (doesn't have to be you), then by definition that is the market price, no matter what the office says.

One thing is for sure: If you don’t pay the 200k but someone else does, the office cannot offer you a property for 120k!

I would rather think about why he wants to sell and how the valuation of only 120 market value should be assessed. Are there hidden defects? Is there a toxic waste dump planned next door? Airport, highway, lignite, power line, windmill or whatever?

Then just buy such a property for 120 TE. Can't get it? See....!

Did I say that I want to buy such a property for that price and not pay more?
My initial question was simply about how the taxes are calculated and behave..
How we will deal with it now we will see.
The fact is we have less stress with it and it is cheaper than a new build.
As Altai wrote, we will weigh for ourselves what we want or are willing to give up.

What the market demands is the 200 TE. If someone pays that (does not have to be you), then that is by definition the market price, no matter what the authorities say.

Well, well..

I think the valuation was carried out in the same way I already wrote. For the plot size with the age of the house and the standard land value, there is a value. This is added to the living area depending on the standard. According to the office, this is the calculation. If then a value x comes out in this region, why should it be wrong? Just because it is more expensive where you are? Central location in the village, no airport, no highway, where do you think a standard land value of €24 comes from?

If a value x comes out in this region, why should it be wrong? Just because it is more expensive where you are?

No, prices have tripled in recent years. In our area, they have even quadrupled. Of course, this can vary regionally. But the benchmark that’s in some file from ages ago, you can shove it where the sun never shines. What matters are the current values in the region, for example on sales platforms. That way, you can get a better idea of where things are headed.
