Construction costs are currently skyrocketing

Something about the current situation here on site. In a popular storage area, there is currently the tempting opportunity to buy a single-family house and a semi-detached house in an advanced shell construction stage. The single-family house with 160m2 for only €500,000 and the semi-detached houses with 135m2 for only €400,000. For that price, only

That's still acceptable.;)
A good year ago, the shell of a bungalow was standing in the area for 520k. But it had already stood there for about 3 years. Roof on, windows in, no rough installation, or similar.
In an area where plots of land cost around ~100k.

Depending on the area, I consider it a fair offer. In the case of the 135m2, that is 2962€/m2 and the land is already included. How big are the plots and what is the BRW? And I assume you can still negotiate. It’s a great opportunity for anyone who wants something new but doesn’t want a 2-year lead time and all the current uncertainties.

The BRW is at 95€ and in half an hour you can be in the state capital by car. So it’s not badly located, BUT I would have concerns with such a project (with several semi-detached houses) and a street in a residential area whether the developer will at least build the road to the houses. Or you don’t want to buy your semi-detached house and the one next door just rusting away in shell condition. That would be too risky for me, but clearly it might be an option for some.

Okay, with the BRW I would still try a lot during the negotiation.

Yes, exactly. It's flat land. And the next supermarket is 8km away. And until 2019, you paid 3k per m2 with land and everything turnkey.

With us, existing houses - 20 years and older - are like lead in the net. At the same time, new rental properties (semi-detached house and granny flat) are selling like hotcakes at high prices.
