House price forecasts have weakened: what that means for your suburb
House price forecasts have become more cautious, giving Western Sydney buyers and sellers another reason to review their plans. But a forecast is a scenario for a broad market, not a valuation of the home you are considering.
What CommBank changed in its November outlook
In an update published on 3 November 2026, CommBank economists forecast national dwelling values to fall around 14% from peak to trough, compared with around 9% in their September outlook. Their forecast for Sydney was revised to around 16%, from 13% previously.
The bank's update cited a 1.2% national fall in October and values 6.7% below their March peak. The recorded changes describe what had already happened. The peak-to-trough forecasts describe the bank's expectation for the whole decline, including the portion already recorded.
It would therefore be misleading to read a 14% peak-to-trough forecast as a prediction that prices will fall another 14% from today. National and city indices also cover different property mixes and starting points. They should not be applied directly to an individual address.
Use house price forecasts alongside local evidence
For Edmondson Park, Austral, Leppington and Bardia, start with completed sales of genuinely similar homes. Compare land size, accommodation, condition, street position and the timing of the sale. Asking prices show a seller's expectation, not necessarily the amount a buyer will pay.
A detached family home and a small apartment can respond differently to the same interest-rate environment. Even within one suburb, presentation, maintenance and competing listings can affect the result. A city forecast is a prompt to investigate, not a substitute for that investigation.
For buyers: prepare rather than try to pick the bottom
Decide what you can comfortably afford and why you are buying. Moneysmart notes that a lender's maximum offer is not always an amount a household will feel comfortable borrowing. Leave room for buying costs and ongoing expenses, and have your lender confirm the current finance position.
If you wait, consider how rent, savings and the availability of suitable homes affect your plan. If you proceed, avoid assuming that a lower asking price removes the need for inspections and contract review. No forecast can guarantee the best date to buy.
For sellers: review the competition, not just the headline
Ask for a current appraisal supported by recent comparable sales and competing properties. An older estimate may no longer reflect current conditions, but subtracting a broad forecast percentage is not a reliable pricing method either.
If you are also purchasing, look at the sale and purchase together, including settlement timing and costs. Keep your decision tied to your household's needs rather than an expectation that every property will move by the same amount.
CommBank's outlook remains a forecast and may change as interest rates, employment and demand evolve. This article is general information, not personal financial or legal advice. Speak with a licensed adviser or conveyancer about your circumstances.
