Construction costs are currently skyrocketing

It's not that simple. An interest rate increase ruins the highly indebted Southern European countries. That is the significant difference between the FED and ECB.
A solution to the problem is not in sight. The ECB hopes that the high inflation is only temporary... if not, we have a serious problem.

Phew, what can I say? An interest rate increase is of course a problem for some member states. But what is the solution: to provide permanently free money and thereby risk inflation getting out of control sooner or later? For some time, the money printing machine will certainly still be running, but that cannot be a permanent state - especially when interest rates are being raised around us in a globalized world.

As someone else already wrote in this thread: Depending on the financing amount, even 0.5% higher follow-up interest rates can lead to real problems.

These have long been decoupled from inflation in Germany. And it appears that nothing significant will change about that. How could it?

Can you provide official sources? I only find the opposite. Slightly rising real wages on average over the last 30 years. In the period 2000-2009 they indeed fell, but the situation relaxed again afterwards.

Every major investment is a bet on the future. And yet, the sentence often proved true for me that my old boss used to say repeatedly: "Waiting costs money." Sounds like capitalism, is capitalism. But even with many uncertainties, it still holds true again and again. In a way, it's a bit comparable to the retroactive installation of a [Photovoltaik Anlage]: subsidies are lower than they were 10 years ago, and so is the feed-in tariff. And yet: with every day you don't do it, you simply don't have it. :)

I am currently reading that NRW has announced a new funding program for homeownership. And in Hamburg, the real estate transfer tax is supposed to become more expensive from 2023, but special discounts are planned for families.

The Building Energy Act is supposed to be revised and tightened this year. It is supposed to introduce stricter new construction requirements and the solar roof obligation. In Baden-Württemberg, they are pretty fast, the solar roof obligation already applies from next May, so in four months. Other federal states will follow in 2023.

In addition, since 01.01.2022, as announced, the new rules for chimney height have applied.

I am curious whether and what consequences this will have for single-family house construction and whether all this will also affect multi-family house construction.

Regarding property tax, I do not yet dare to make an assessment whether it will rise or fall in Saxony. Saxony has not joined the federal model. For the undeveloped 567 sqm plot, we currently pay 56 euros annually. :)

In Baden-Württemberg, they are pretty quick, the solar roof mandate applies already from next May, so in four months

But it has nothing to do with the traffic light coalition, rather that we have a green minister-president ;) That was the result of the coalition negotiations from almost a year ago
