I own and manage some real estate. A few weeks ago, a tenant moved into one of the properties I manage after signing a 12-month contract. The property in question has a jacuzzi in the back garden for which the tenant has requested instructions for use. You should check the terms of your rental agreement – it is possible that your rental agreement contains an explicit provision allowing the tenant to remove the tenant`s furniture within a short period of time after the expiry of the term, although such a term does not bind an entering tenant/user to the terms of a new rental agreement. What constitutes a “device” is most often obvious, including elements such as fixed lighting, heating systems, sanitary taps, etc.
