[*]House + land approx. €407,000 WITHOUT the aforementioned ancillary building and other costs.
[*]NRW - Krefeld
[*]Broker commission only on the land, is about €4,000
Ok. Then the land registry and notary alone are almost €37k, plus broker, so you're already out about €41k for the incidental purchase costs.
In addition, there are further ancillary building costs such as utility connections, civil engineering work, drainage, government fees, etc., which are another €20k or more.
Outdoor facilities, carport/garage, surveying, furnishings, kitchen are also missing.
And who knows what else is missing in the turnkey offer!
You can forget the estimated sum of the broker.
