Compare your proposed rent with recent listings for similar properties nearby, considering the number of bedrooms, condition, parking, inclusions and location. Check several established rental websites and, where possible, look at comparable properties that have recently been leased rather than only advertised prices. Rent increase notice periods, frequency limits and dispute options vary between Australian states and territories, so check your state or territory’s tenancy authority before responding. If the increase seems unreasonable, you can ask the property manager for evidence or seek advice from a local tenants’ advice service.
