These properties in better locations can hardly or no longer be afforded by your home handymen. Now only the people who bring the 600,000€ for the demolition house from the 1960s come, and they certainly will not move in there initially. In other words - it will be extensively renovated by companies. And indeed, values come out that would be above a corresponding new build - because the market (which is completely bad here) simply allows for the fact that in addition to the land value, dream values for the old stones are also paid. There are hardly any alternatives and the desperation is great. A house from 2010 costs on the oh-so-efficient market gladly only about 70,000€ more than a renovation case 50 years older. But we don’t have a bubble. ;)
No, that simply makes no sense. The market does not work that way. You also have to compare apples with apples. The new build would have to be built on a plot of equal size in an equally good location. That simply does not happen. If a plot in the 'old building' area actually comes onto the market, it costs almost as much as the old building, but you start from zero. A renovated old building at new build level is simply, due to e.g. better location, still having a cellar, larger plot, etc., also worth more than the new build in a new build area. The market works very reliably there. People regularly come here and calculate that they cannot afford old building + renovation, so they would build new... there is always a lot of naivety involved.
