Kernrechtsfrage
Whether the parties had a valid lease agreement with an agreed rent or instead an incomplete mixed contract requiring gap filling.
Extrahierter Entscheid
The parties had a mixed contract: use of the property in exchange for services, with the contract incomplete on the consequences of withdrawing the management mandate.
Extrahierte Begründung
The factual findings showed agreement on services in return for housing, but no proven agreement on the exact monetary rent. The contract had to be interpreted as a unitary mixed contract.
