Buy a terraced house from 1987 for 385,000 EUR?

What do you mean by solid impression. When there is plaster on it, you cannot visually tell whether it is concrete or timber frame construction ...

Well, it just has twice the living space.
Is there a development plan there? A floor area ratio of 0.67 is quite substantial, that's hardly ever allowed anywhere.
If everything is still as original as the heating, a renovation will sooner or later be necessary. Heating, plumbing, electrical, windows, etc. With that living space, certainly well into the six-figure range. If that was good standard back then, you can probably live with it for another 10-15 years.
But if you like it and can afford it, why not? I also often find older houses more attractive than cookie-cutter new builds with open living spaces and ETICS.
35KW is suitable for the living space.
I have an 18KW oil boiler for half the living space.
That’s how it used to be, out of the chimney with the coal :-)

So about the price: only the market situation can show you whether the price is justified.

Basically, you should have the house inspected by an expert.

Primarily, the personal impression when walking through the rooms must be right: I want to live here! you have to say that in your head. After all, the floor plan must fit your personal life.

A 30-year-old house needs renovation; partly to a considerable extent – windows may be outdated, the heating system needs to be replaced. The energy values mean nothing to me as a layman, but they probably do not correspond to what you are paying now. So quite possibly, you can still invest a large sum of money in an aging house. Older houses usually have more charm than new builds, which should not be underestimated. It’s also about preserving value, but that costs money. Whether the walls seem more solid or actually are, I don’t care and it’s irrelevant to me. Timber frame is not solid, yet not bad or inferior. I would certainly not put a house on a priority list based on that. Ultimately, it depends on whether there is a good living atmosphere and coziness.

Is it great to have only high earners or academics as neighbors? For me, it’s the mix... usually, a simple craftsman next door is more relaxed and straightforward.

Best regards in brief

... thus possibly simpler than a graduate [emoji4]

Regarding the size: plenty of space is great. But too much space than one needs and ultimately occupies can also be a burden. Heating costs and cleaning, if neglected, can quickly cause a house to partially fall into disrepair or the rooms to be used carelessly just for storing bulky waste.

In short, greetings

Yes, that's true,

the residential location is really very pleasant - I feel "at home" there.

However, I will still hire a building surveyor to inspect the condition of the property - better safe than sorry ;)

Thank you very much for your opinions.
