Sydney property prices are falling more sharply, yet buying a home is not automatically becoming easier. Higher interest rates are squeezing borrowing power at the same time as values retreat. For buyers with secure finance, weaker competition can create room to negotiate. For households already stretched, a cheaper property may still come with an unaffordable mortgage.
Sydney property prices keep falling
Cotality’s September figures put Sydney dwelling values 8.6% below their February peak. National dwelling values fell 1.1% during September, extending the downturn to six consecutive months and leaving values 5.2% below their March peak. Reuters
The slowdown is also visible in activity. Cotality estimates Sydney home sales over the past three months were 26.5% lower than a year earlier. Fewer transactions point to buyers holding back, rather than a market where every lower asking price immediately attracts an offer.
These are broad dwelling measures covering houses and units. They do not mean every Sydney property has lost the same amount. Recent comparable sales remain more useful for pricing an individual home than applying the citywide decline mechanically.
Lower prices, tighter borrowing
On 29 September, the Reserve Bank raised the cash rate by 0.25 percentage points to 4.60%. That adds another financing hurdle for buyers and repayment pressure for existing borrowers. RBA
Emerging University of Sydney research helps explain why this matters beyond the next repayment. Dr James Graham’s modelling suggests a single 0.25 percentage point rate shock can reduce home purchases immediately and affect home ownership rates for more than a decade, with younger, lower-income households most exposed.

These are early modelled findings, not a prediction that every buyer will be delayed for ten years. The practical lesson is to refresh borrowing capacity and protect deposit savings rather than assume falling prices will solve affordability.
The recovery remains uncertain
Westpac’s September Housing Pulse forecasts a 7.3% peak-to-trough decline across its combined five-major-capital-city measure. It forecasts Sydney dwelling prices falling 10% during calendar 2026, with stabilisation and recovery a 2027 prospect. These forecasts were finalised before this week’s RBA decision. library.westpaciq.com.au
The distinction matters: a Sydney calendar-year forecast and a five-city peak-to-trough forecast measure different things. Neither establishes where today’s market bottom sits.
Westpac also identifies limited selling pressure and relatively tight supply as potential cushions. Listings can accumulate when sales slow even without widespread forced selling. Buyers may gain negotiating time, but the evidence does not justify assuming every vendor must accept a heavy discount. Westpac IQ
Prestige faces different pressures
John McGrath’s commentary highlights why scarce prestige homes can behave differently: wealthy buyers often rely less on mortgages, while capital availability, property quality and international uncertainty carry more weight. Real Estate
However, the latest McGrath Sydney Spring report shows a mixed picture. Sales above $5 million fell 19% in the year to the second quarter of 2026, while sales above $10 million increased 2%. That supports resilience at the very top, alongside softer activity across the wider prestige segment. McGrath Estate Agents
For Sydney buyers, the approach is straightforward: confirm finance, assess current comparable sales, investigate the property thoroughly and leave a cash buffer. Sellers need pricing that reflects today’s evidence. A weaker market rewards preparation; it does not remove the cost of buying or selling the wrong property.
