A Guest substitution is a break of the rental contract agreed to by all parties, after which a new contract is made, with new Guests named in the contract.
For this to proceed smoothly, there needs to be agreement between the outgoing and incoming Guests on the condition of the property at the time of the change.
You, as the outgoing Guest, should liaise with the incoming Guest who will need to visit the property ahead of the new contract start date, to establish what existing damage/wear and tear there may be to the property. You should provide them with your move in inspection report, and compare the condition of the property in that report, to the condition at the time of the contract change.
Bear in mind that after you move out, they as the incoming Guest are taking responsibility for the condition of the property, which will be judged at the end of their stay. Please make sure that any possible confusions or concerns about the property condition are made transparent and resolved in good time between you all, before you leave.
If there has been property damage during your stay, you should inform the incoming Guest and work out how to compensate them/the Owner. For example we could deduct from your deposit to cover the repair cost, or you could make a direct payment to the incoming Guest to cover that cost.
Before you move out and leave responsibility for the property as a renter on the contract, please be satisfied about the condition of the property you are handing over, and confirm that to our team in writing.
