Current financing offer from the house bank

Well, the Bundesbank states 15-40% in big cities. You always have to consider that new rents aren't cheaper either. So there's only one alternative left: moving to a cheaper city. And will that happen? Questionable.
East a bit the dilemma one has

And for exactly those reasons and so as not to burden ourselves with the topic at all, we have agreed on a fixed interest rate for the entire term (30 years) at 1.45% and have waived all components that, for example, only have a 10-year fixed interest period. At the same time, we have not fully utilized the installment and the property, so that the installment can easily be paid even in an emergency with one income or with the current inflation.

I have written and read this here several times: Everyone has to make a risk assessment for themselves and consider what they can and want to afford. Restricting our lifestyle because of a house would never have been an option for us and we will not have to do so despite the current inflation.

The ECB cannot do anything more this year, there will be at most one interest rate hike. For bigger steps, it would have had to announce earlier; currently, it is rather in the "hmm yeah maybe it won't stay at 0%" rethinking phase.

The long end of the yield curve is only partly related to ECB decisions. Interest rate swaps have already risen significantly, and given inflation, this was also foreseeable. As long as Germany remains in the Eurozone, we will probably not see mortgage rates of 5% or more, but I consider 3% realistic in a few years. Due to inflation, this is not such a big problem. Most people will also earn 20% more in 10 years...

Well, the Bundesbank states 15-40% in major cities.

No, it states "cities," not just the top 7. It was already clearly communicated last year that the exaggerations are not limited to individual metropolises and their surrounding areas. That is why there is also the range.

but I consider 3% realistic in a few years. Due to inflation, this is not such a big problem. Most people will also earn 20% more in 10 years…

Translated this means: Due to the, for example, 500 € higher income, one can easily pay 700 € more every month. The calculation doesn’t really add up for me. :rolleyes:
