Key points for spontaneous house viewing by a layperson

They are selling the kitchen (built in 1978) as inventory, an old study room wall unit, garden tools, a sauna, and some grandma chair for the stairs. Everything we were going to throw away anyway. I find that pretty lame and somehow cheeky.

We wanted to make an offer anyway. But the tip about the deadline is a good one, thanks.

In the counteroffer, I would appreciatively mention the inventory items, explicitly without any reality check the garden tools and the sauna (with the praise: "you have assessed that very accurately" exactly with the stated value, offset by the estimated disposal costs for all the other junk. The seller side will have to digest that first. Nevertheless, set a clear sign with the binding period of the offer.
Most cheap used properties in the market segment "builders counted among the top performers during their active years" are cheap because the sellers ruined the property by scaring off interested parties with their "value" ideas for sentimental junk.

Isn't the inventory more of a trick to reduce the real estate transfer tax? It's hardly about the house being available for 20K less without inventory, but rather the final price is fixed.

Yes, lower additional costs, but financing can become more difficult because you waste your equity on junk and it no longer contributes to the house value.

So I would set a price x for everything together: house + inventory. But just as said: appreciating and praising the good condition. To what extent the sellers want to split the price x into house and furnishings, they can decide for themselves. In the end, it doesn’t matter.

Sure, 20k for junk is a lot of money, but with a 600k€ property + 100k renovation, it’s "only roughly 3% more."

Expensive 3% that really bother me a little. The purchase incidental costs were also a thought. But then I remembered the first conversation where they wanted to sell everything before continuing. Apparently, they didn't manage that.

And how much does the square meter cost?
You „need“ 700-800 sqm?

That seems to be a huge house with potential, 169 sqm living space, basement how many sqm, the same amount?
And the attic can still be developed.
Something comparable NEW on a plot of this size easily seven figures.
(Because here you would also end up at about 800 k€ - until ready to live.)

Square meter around 130-150€
We would like a nice big garden.

The basement is a living basement. It is already included in the sqm. The attic is very low, not worth developing but it is big enough for us.

You just have to keep an eye on it. Year of construction 1978 is already more than 40 years ago. Electrical, pipes, heating, roof, windows, doors. All of that actually gets old over time. If you want to live in it for another 40 years, it will be a permanent construction site. The price is then quite ambitious.

We have received the conclusion of the report. How should this be interpreted based on your experience?

Thank you for any input.
