Construction costs are currently skyrocketing

Allianz 30 years full amortization, +0.48% in the last 3 weeks

What was the overall interest rate? I would be interested.

But unfortunately not in connection with the increased purchasing costs.
Realistically, almost no one could afford today's house prices if the interest rates were at 3%. As long as interest rates and house costs are not considered together, it is completely pointless to discuss absolute levels.

However, even with a 3% nominal interest rate, prices will not fall. Demand is there; only potential buyers without equity are excluded from the start. So, it's just 20 instead of 100 fighting over a property.

On January 28th, Schwäbisch Hall offered 100% loan-to-value ratio and 10 years fixed interest standard condition at 1.8%, today new condition 2.35%. 100% loan-to-value and 30 years fixed interest rate 3.2%. And this is only in anticipation because the ECB is announcing interest rate hikes. Those who only took out 10 years fixed interest to save 0.2% will be surprised... despite inflation and possibly salary increases over time. We have sold almost exclusively maximum fixed interest rates to our customers.

can you tell me why Schwäbisch Hall is so expensive? Is it a home savings contract? Sure, it is an insurer and not a bank. What advantages does concluding with SHA have compared to a bank?

With significantly rising interest rates, newly built houses will definitely become significantly cheaper.

Why?
You can follow the discussions here: 180 sqm for two people, gym and wellness in the basement, KNX costs €75k, we would like wood-aluminum windows with floor-to-ceiling glazing, expensive exterior blinds, children already need 25 sqm for themselves.
We will come back to building what we need and can afford. That's how our parents/grandparents were able to build with interest rates of 8%.

P.S. With such rates, only a repayment of 1% was necessary to pay off the house in 32 years.

P.S. At such rates, by the way, only a 1% amortization was necessary to have paid off the house in 32 years.

I have a different opinion here. I think that houses nowadays are really built simply and down-to-earth. Sure, those who have some buffer build a bit more luxuriously (KNX, 3 bathrooms, huge windows...). However, the vast majority do without that. Look at the houses from the 70s. Those were almost exclusively architect-designed houses, with elaborate floor plans, often split-level, party cellars, sauna, maybe an outdoor pool... plot size 1000 sqm... In our area, these houses are very sought after and rarely available for less than 1 million. I've only found a handful of new builds with similar features in this area.

Sure, it is an insurer and not a bank.

It is a bank and building society with a mortgage bond license - not an insurer ;)
