Request for advice on property financing

Thank you for the tip,
I will check the possibilities of a regular consumer loan.
However, I have informed myself again about the fees for the [Grundschuld] cancellation.
I think that the fees for the registration and cancellation of the [Grundschuld] on the property are within an acceptable and manageable range.

An assignment should be cheaper than deletion and new. A consumer loan with a term of 1-2 years will be significantly more expensive than the other two options.
