The article is number 14, so it's a basic right – articles 1 through 19 – we open our constitution with our rights, we don't add them as an afterthought in some amendments. ;-)
So paragraph 1 guarantees property and inheritance. And makes both subject to limitations, set out by law (freedom of art, for example, is not limited by laws, at least not literally in the text of the constitution).
Paragraph 2 lays out one such limitation: social benefit.
Paragraph 3 lays out a means to achieve that: expropriation (exceedingly rare, I think it is sometimes used for huge infrastructure projects like Autobahnen or railroad tracks, but only after years of negotiations).
So it is indeed a general rule, not a detail to expropriation.
To your question about the limits on paragraph 2 let me just throw in a bit from the German Wikipedia, without having checked it:
* Not all property is subject to this limit to the basic right to property, but only such property that has "social relevance"
I would interpret it so that apartments and housing are clearly having social relevance, but your Porsche probably hasn't.
Furthermore:
* Those limitations to the basic right to property must be rooted in fomal law, not just regulations or jurisprudence.
