Plot on a slope in the Munich outskirts - how to decide?

the issue with a slope is that you should build WITH the slope, especially if you want to optimize costs. And therefore it's better to build the ground floor into the slope rather than having a full basement. The more extreme the slope, the more I would prefer to go to an experienced slope architect from the region rather than a prefab builder who (in my opinion) mostly relies on standard solutions.

Yes, you are right. I also expressed myself poorly there. I certainly meant a basement level, but built with the technique of a cellar, just with a lot of glass.

Pinkiponk, to my knowledge there are no standardized prefab houses for slopes - as I said: because every slope is different. But maybe you know some?

Speculation tax, to my knowledge, only disappears after 10 years.

And in a hillside house I would not call the basement a souterrain. That gives a false impression. You exit there at ground level; at the height of the terrain there. Souterrain is below the top edge of the terrain.

I meant that prefab house builders also offer houses for a slope, and I may have, perhaps mistakenly, referred to these houses as "off-the-shelf houses" in contrast to an "architect-designed house."

No, there was nothing mistaken about that. The general contractors – you can lump the Steiners with the wood builders in the same bag, at least the big names; the smaller ones like Wirlebenhaus, Staudenschreiner & Co probably behave a bit more properly – "all" of them can’t keep their plans-in-the-drawer fingers to themselves when someone comes with a sloped plot: oh, we have our standard model zero-eight-fifty in the always-popular edition; we just add a basement under it and presto, you can hardly tell it anymore; it suits you excellently, dear lady, it even makes you look slim. Against this stands the not-at-all genuine myth that an architect would plan and/or build at a higher cost. I belong to the people who explicitly do not believe that you only build a house once, but for a catalog house with a wallpapered hobby basement, my money would be too precious.

Thank you for the numerous responses - that already helps us a lot!

We have an initial consultation/site visit with an architect at the property over the weekend.
What questions should definitely be asked about the sloping plot? What must be clarified without fail?

In the south of Munich, the ground is sometimes difficult to build on. A soil survey would therefore be important so that the problem of the slope does not also become the problem of the soil.

Buy! The slope isn't that steep. Don't buy if you are eyeing a mainstream standard villa from a catalog. You should tailor the house a bit to the plot. But I only see 100-120cm over 10 meters... that's fine ;)
