Refinance existing loans with a construction loan

Outdoor facilities and incidental costs are already set too low.
I would estimate additional construction costs at the house price to be at least 60,000.

Explanation?

The bank calculates as explained in #51.

Nevertheless, I come to 639k.

Only the notary will already cost you 3000 euros for 466,000. In general, about 10 to 15% of the house price is assumed as additional construction costs. Sorry, I had previously put an incorrect value of 6000 here.

Which notary? I've never done this before, is a construction contract also signed at the notary's office?
