There is always a lot of legend, memory gaps, and truth mixed together and apples are mixed with pears. Even in 2005, the house that today costs 500 K € did not cost 250 K €. I still remember that in our village around 1992, a bungalow was built for 500 TDM (that was the talk of the village back then because it was insanely expensive and the builders had to sell it shortly afterward due to divorce). By the way, if you look at that thing today, it looks like a normal bungalow. Don't say that it hasn't also become more expensive (beyond the normal price increases), but you also get different houses.
