Defensive offer, or have house prices become so expensive?

Oh yes, fun fact: The building is being "sold as is." For other people that would certainly be a deterrent, but for me as a flea market lady, treasure hunter, and fan of [Bares Für Rares]: an additional incentive, I do like to rummage through old stuff. In the basement there is even a very old parquet floor sanding machine and model cars. :D However, realistically, you still have to add the cost of clearance. I think some of the things inside can be sold off cheaply, others we want to keep (partly beautiful wooden furniture) and upcycle, but about 80% is definitely a case for the dumpster.

For me, that sounds more like pseudo-expertise in the field of old buildings. And 1500 €/sqm is the price that has been repeated in every article on the web or in the newspaper for over 10 years, but which is far from any reality. You didn’t need an energy consultant, but rather an expert for renovation.

I agree with you to the extent that it also seemed cheap to me. Although he also said that there are practically no limits upwards and that it is difficult to give a concrete number because it strongly depends on what exactly is to be done, how high the demands of the builders are, and which materials are used. That sounds reasonable to me. As an example, he mentioned an old school friend of mine who had wall heating and clay plaster installed throughout the whole house. Of course, that’s nice, top quality – and expensive.

The main building is from 1928, the extension is from around 1956.

How reliable are these data? - I doubt them, especially if the floor plan drawings are largely correct.

I tell you, it always feels like that - especially when diagnosed remotely - no guarantee.

The equipment, its condition, and the inhabitants often reveal more about the expected renovation backlog than any room moisture measurement, thermographies, or the like.

Not more expensive than, for example, underfloor heating and external insulation. They balance each other out. For such projects, you need a specialized architect and a structural engineer. That alone already drives up the costs. Windows also add up, as you almost always need custom sizes in old buildings. Realistically, without personal contribution, the starting point for a renovation is 2000 €/sqm.

In "as is" contracts, I can only advise having an expert/structural engineer inspect the house before purchase. Especially with larger properties, renovations are harder to manage.

The clause is unproblematic for houses. It does not protect the seller from liability in cases of fraudulent misrepresentation or hidden defects, but merely excludes the warranty for defects recognizable by laypeople. This prevents every creaking stair step from being elevated to a warranty case. In my opinion, from the seller's perspective, it belongs in every purchase contract.
