Things That Can Invalidate Your Property Valuation

Why Out of Date Valuations Are Risky

Getting an accurate property valuation is essential for various transactions, from securing a mortgage to determining the selling price. However, certain factors can make a valuation outdated, which poses risks for both buyers and sellers.

The Impact of Age on Valuation

Time-Sensitive Nature

As time passes, the relevancy of a property valuation diminishes. This is mainly because property markets can change rapidly, influenced by economic conditions and local demand.

The Safe Timeframe

Most experts, such as Sydney property lawyers, recommend that a valuation be no older than three months for it to be considered reliable.

Home Improvements That Matter


Significant renovations, like kitchen remodels or bathroom upgrades, can greatly affect your property’s value. An older valuation may not reflect these changes.


Adding a room or an outdoor structure like a shed or pool can also invalidate a previous valuation.

Market Shifts and Their Effect

Economic Indicators

Factors such as unemployment rates, interest rates, and GDP growth can impact property values. An out of date valuation won’t capture these shifts.

Local Factors

Changes in the local area, like new schools or shopping centres, can also significantly impact property value.

Factors You Might Overlook

  • Zoning changes
  • Environmental factors
  • Changes in strata fees
  • Local council rates

Legal Changes

Sometimes, new legislation can affect property values. For example, changes in property taxes or strata laws can invalidate an older valuation.

Steps to Update Your Valuation

  1. Consult a property valuation expert familiar with your area.
  2. Disclose any renovations or additions you’ve made to your property.
  3. Review current market conditions.
  4. Get a fresh valuation report.

By being aware of what can invalidate property valuation, you can take the necessary steps to ensure you have the most accurate and up-to-date information at your disposal.
