Kernrechtsfrage
Whether the buyers breached precontractual duties so that the seller could set off damages under culpa in contrahendo against the repayment claim.
Extrahierter Entscheid
No recoverable culpa in contrahendo damages were established; the buyers' conduct did not justify set-off.
Extrahierte Begründung
On the binding findings, the seller knew of the buyers' financing uncertainty and of the unemployment issue, and no deceptive conduct or proved duty to disclose was shown. The buyers also had no duty to conclude a contract absent a valid preliminary contract in the required form.
