I have been told by my PM that once your tenant signs a 12 month lease you can not put the rent up during that lease. So maybe if you want to up the rent after 6 months, only do 6 month leases...
As for pets... In Victoria it appears that the landlord has absolutely no rights even with a NO PET clause in the lease.... They can do what they(The Tenant) like as long as there is no damage...
Why they even have that clause in the lease is a joke to me!
