We are beginning to plan the construction of our house

Yes, exactly - repay one percent. Then take a look at what happens with the annuity loan when the interest rate is high - then you definitely know the difference (That's why it's called "initial repayment"). It has been (at least for a while) a problem that many repaid very little with the low interest rates, and then the financing runs until the 80th year of life...

From my family circle, I basically only know classic annuity loans for the loan (70s-90s), but life insurance was also (back then) not a bad thing. It was probably a TA loan similar to a building savings contract, right?

But I am 100% convinced that the Americanism regarding living on credit is getting worse and worse. I also sometimes financed something myself (0% financing, 3-12 months), but there are people who need the latest, biggest iPhone every year and at the same time want 4 vacations - and all on credit. Madness...

I'm really stuck now and don't understand this. Feel free to message me privately due to the missing topic in the thread

The higher the interest rate, the sooner the loan is repaid with the same initial repayment. For example, in the past, 1% initial repayment was enough for the loan to be paid off in 30 years. With the current interest rate, about 2.5% initial repayment is needed.

All right, but I will take the 4% repayment today then.

Then you would have been finished after 14 years at 8% interest, now at 2% interest you will only be finished after 20 years.

Ypg means it more like, if mA. has 10% available, the difference is 2% repayment earlier to 8% repayment nowadays. After all, even if the term were longer, one could afford a loan twice as expensive and still have 3% repayment in the same installment...
