What is the interest rate lock period in construction financing?

Our Interhyp advisor told us that ING can switch twice for free and from the third time on a processing fee of €100 would be due.

That’s what we were told too.

I believe that if you make the repayment change online, it is even always free (I think I remember having read that)...

Yes, I also think I remember that it should be significantly more than just 2 times at ING. At Volksbank, it is possible up to 5 times for free, and beyond that it is chargeable (only manageable processing fees).
