Key legal question
Whether the contract required the buyers to pay the mortgage debts in addition to the agreed price
Extracted holding
The sellers failed to show that the contract imposed any payment obligation beyond the agreed price of CHF 1,930,000.
Extracted reasoning
The cantonal court's factual finding of the parties' common intent was not shown to be arbitrary; the contractual wording and surrounding evidence supported a total price including the mortgage debt burden borne by the sellers.
