Construction costs are currently skyrocketing

How high do you expect interest rates to rise in the next 10 to 15 years that you want to commit yourself to 2.92% for 30 years?

Can't you exit after 10 years anyway? So in case the interest rates are then below just under 3%

Can’t you just opt out after 10 years anyway? I mean in case the interest rates then are below just under 3%

Yes. But you have paid the interest surcharge for 30 years compared to 10 or 15 years for 10 years. That can easily amount to several hundred EUR/month…

So 10 and 20 years are not that much cheaper and if the interest rates go significantly down sometime between year 10 and 30 I can simply switch and if not I did everything right anyway

And I still have a loan on my other property, which is partially sold and rented out, at 1.8 percent interest, which still runs for 15 years

June commissioned and today the heat pump is being delivered spontaneously ([Großhändler hat/hatte aktuell 3x unser Modell - Novelan WSV 6.2K auf Lager]), so no instantaneous water heater will be purchased for the winter after all.

When we financed back then, we also preferred to rely on security rather than saving the last cent on interest. When we bought, the fixed interest rate for 10 years was still between 0.6 and 0.8%, and everyone laughed at us and shook their heads because we took the loan at 1.45% with a 30-year fixed interest rate and explained to us how much interest we could have saved monthly.

To be honest: We simply didn’t feel like worrying about what the interest rate level might be on day X, what the remaining debt would be until then, how to secure it, etc.
