What is the interest rate lock period in construction financing?

I was thinking about a house sale.. for whatever reasons..
You mean 2 1/2 years?? Where does the 1/2 year come from?

The 1/2 year is the notice period of 6 months that you have after the 10 years.

So the prepayment penalty is calculated up to the reaching of 10.5 years.

It's currently coming up for us too :rolleyes:

The half year is the 6-month notice period that you have after 10 years. So the early repayment compensation is calculated up to reaching 10.5 years. This is also currently due for us :rolleyes:

...but everything is only calculated from the full repayment of the loan and not from the start of the credit agreement.

...but everything is calculated only from the full disbursement of the loan and not from the start of the credit agreement.

... and if contractual changes took place after full disbursement, only from that date

How is it actually after the fixed interest period?

Can I also do the follow-up financing with another bank?
Or is the effort usually too great because the new bank has to be registered again in the land register?

...but everything is calculated only from the full disbursement of the loan and not from the beginning of the credit agreement.

So if I understand correctly.. (example house sale after 8 years)
with a 10-year contract - 2 years prepayment penalty
with a 15-year contract - at least 2 1/2, but rather up to 3 or 3 1/2 years prepayment penalty?

Doesn't that make the decision about which term is "better" not easier either, right??
Personally, I tend to prefer shorter terms.. But this feeling probably dates back to times when interest rates were 5%. I closed my first mortgage in 2000 with a 5-year term. I was lucky.. it steadily went down. The follow-up financing was always for 5 years as well. This later benefitted me when selling the house. The prepayment penalty was limited. For the current house, we chose 10 years (about 1% interest rate).

I am a friend of security. We are now terminating an ongoing financing at the end of the 10 years (had 15 years fixed interest rate back then) and refinancing with a fixed interest rate for 25 years. Ten years ago, interest rates were significantly higher and hardly anything was repaid, plus the new loan has to be higher. Still, the future installment will be almost 100€ lower and everything will be paid off in 25 years. The offers for a shorter fixed interest period were only slightly cheaper, and so we have the security that we know exactly what we pay and when everything is paid off.
