How so? Surely some tenants will be glad to have security of tenure for a speficified period under a fixed term lease even if others want more flexibility? I'd assume that the legal position is that which pertains to any similar contract between private parties.
A better rental model would be :
- open ended contract i.e. no end date
- controlled annual rent increases
- 1 month notice required by the tenant to the landlord
- 3 month notice required by the landlord to the tenant
