I have a 4 bedroom town house in coopers plains rented to 2 taiwanese tenants. They signed for a 6 months leased extension. Comes inspection time, all bedrooms are full. They had another 3 occupier. I suspect they had illegally rented out the 3 bedrooms and earn extra cash. Supposedly they can rent out 200 per week for one bedroom, they would be staying for free. In this case what can I do? Is there any compensation I can get from them? a. I can chase them out of the house and issue a termination notice? for breach of tenancy agreement? Considering the market is not strong, I may have to wait 1-2 months for tenancy. b. I can make all of them to sign on the lease. Which considering they are students, would I incur more wear and tear? what kind of compensation is justifiable? the current rent is $575 per week, just renewed. I am thinking, why not I take over all of them and renegotiate the terms again? c. I can force chase out the extra tenants citing they are not in the lease in the first place and only allow the original 2 tenants. Can I do that? What other course of actions do I have? I want to quickly resolve this and not let the tenants profit on my property.
