A tenancy is associated with a property. You must therefore identify and select the required property:
From the resulting view of property details select the "Tenancies" tab. This tab will list all tenancies associated with the property (if any). Then...
- Identify the required tenancy
- Click on Action "Edit" (Pencil Icon) to the right of the identified tenancy
You may make changes at this point, then select Update Tenancy or Cancel if no changes have been made.
