Kernrechtsfrage
Whether the buyer could invalidate the sale for essential mistake about permanent habitability.
Extrahierter Entscheid
No. In light of the contractual warranty exclusion and the buyer's own declaration about verifying zoning and use possibilities, permanent habitability was not an essential element on which she could rely to avoid the contract.
Extrahierte Begründung
The parties expressly shifted the legal risks linked to the property's location outside the building zone to the buyer; the buyer could not in good faith treat permanent habitability as a necessary contractual element.
