Every four years, Landgate revalues all properties in Western Australia for rating and taxing purposes under the Valuation Land Act 1978. Landgate collect and analyse property details to determine the Gross Rental Value (GRV).

Understanding your property revaluation

Every four years, Landgate revalues all properties in Western Australia for rating and taxing purposes under the Valuation Land Act 1978.

In 2023, the City of Mandurah received the latest property revaluation information from Landgate for all properties in Mandurah and the new value will apply to how your rates are calculated. 

Why does it occur?

A property’s Gross Rental Value (GRV) provides a basis to determine property rates, service charges and levies. In this situation, the GRV directly impacts the money you pay in rates.
The GRV information is provided to your local government, water provider and other rating authorities to calculate your charges.

Want to know more?

If you have any questions about the GRV valuation or to lodge a revaluation objection, please contact Landgate.
