Construction costs are currently skyrocketing

You always assume that the plots and houses become more expensive - wrong! The euro just becomes less valuable

Nonsense. Then it would be inflation and other countries also use the euro...

No nonsense - and inflation is completely wrong in this context

Hmm...then it is interesting that the devaluation of the euro in Germany alone was quite different regionally last year.
According to your logic, the euro lost about 12% of its value in metropolitan areas. In urban districts only about 7%.
All based on the price development of single-family and two-family houses.

The depreciation of the euro looks different again when it comes to apartments.
Strange ..

You received a concrete offer without a proper planning being carried out? How is that possible?

The process was as follows: 1. Planning was done. This could still be adjusted for months. 2. Offer received based on the planning. 3. Planning contract concluded (5% of the offer amount). If this is concluded within 2 weeks after the offer, the prices apply until the end of construction. 4. Building application made at the end of December. Building permit expected around the end of July. 5. Sampling already carried out. The additional services are agreed directly with the trade. 6. Construction contract will be concluded in June. 7. Financing then afterwards. I have already obtained offers in advance. €30,000 paid so far from equity capital. I will reclaim this amount through the financing.

You always assume that the plots and houses get more expensive - mistake! The euro just keeps losing value

And how do you explain that the exchange rate in Poland is rising. It was already at 1 € = 4.60 PLN. Before the pandemic at 1 € = 4.20 PLN

In our municipality, just under a dozen building plots were released for slightly under 100 €/sqm. The interest is said to be quite high.

Where are they located? In the Hunsrück? Or did you actually mean to write 1000€/sqm? :)
