03 Feb Mosman Premium Property Market: What 2025 Revealed About Prestige Housing

A Record-Breaking Year for the Mosman Property Market

2025 was a landmark year for the Mosman property market, particularly at the prestige end. With a new suburb house record of approximately $50 million, and two additional Mosman luxury homes selling above $40 million, Mosman has firmly cemented its status as one of Sydney’s most tightly held premium suburbs.

While Mosman does not yet rival the absolute peak prices achieved in parts of Sydney’s Eastern Suburbs, the depth, resilience and consistency of the Mosman prestige property market remains exceptionally strong.

Many of Mosman’s most valuable homes never transact at all. Large waterfront estates and tightly held landholdings along Hopetoun Avenue and Burran Avenue are rarely offered for sale. If these trophy properties were to come to market, they would likely reset Mosman’s suburb price record once again.

Mosman’s New Prestige Sales Benchmarks

The $43.5 Million Chinaman’s Beach Sale

In the second half of 2025, Mosman’s long-standing $40 million benchmark was surpassed by the $43.5 million sale at 4 McLean Crescent.

With absolute beachfront access to Chinaman’s Beach, expansive water views and exceptional privacy, this property represents the type of irreplaceable asset that continues to attract both local and international buyers to Mosman’s luxury home market.

The ~$50 Million Golden Triangle Record

Shortly after, Mosman’s suburb record was broken again with the circa $50 million sale on Kirkoswald Avenue.

Located in the heart of Mosman’s tightly held Golden Triangle, this prestige home combines scale, elevation and sweeping water views over Balmoral Beach — a combination that consistently commands a premium and underpins long-term value.

A ~$40 Million Sale in December

In December 2025, another prestige Mosman home sold at 28 Ruby Street.
While the price was undisclosed, it is understood to have transacted at approximately $40 million, reinforcing the depth of buyer demand for large landholdings with views — even beyond headline-grabbing record sales.

What the Data Shows About Mosman’s Price Depth

Mosman’s premium strength is not limited to a handful of exceptional sales. The suburb continues to demonstrate strong transaction volume across multiple high-value price brackets.

Mosman house sales by price range (2025):

• $20m+: 6 sales
• $15m–$20m: 10 sales
• $10m–$15m: 30 sales (~20% of all Mosman house sales)
• $7m–$10m: 44 sales (~29% of all Mosman house sales)
• $6m–$7m: 25 sales
• $5m–$6m: 35 sales

👉 Around 31% of Mosman house sales in 2025 transacted above $10 million, underscoring the suburb’s depth at the prestige end of the market.

Flow-On Effects Across the Broader Mosman Market

These ultra-premium transactions have a clear halo effect across Mosman, particularly for homes outside the Low and Mid-Rise (LMR) Housing Policy zones.

Buyers are increasingly paying a premium for properties that offer certainty around:

• Long-term views and natural light
• Privacy and streetscape character
• Traffic, density and congestion
• Lifestyle protection and resale appeal

As a result, tightly held streets unaffected by future density changes continue to outperform.

Buying Opportunities Within Low and Mid-Rise Zones

For homes within or on the periphery of LMR zones, buyer sentiment is more cautious. Uncertainty around future development, overshadowing and congestion has softened demand in some pockets.

For well-advised purchasers, this has created select opportunities to secure Mosman homes below intrinsic market value, particularly for buyers with a longer-term outlook who are comfortable balancing planning risk against price.

Why Local Expertise Matters in Mosman

Mosman’s prestige property market is not slowing — it is becoming more segmented.
The gap between exceptional homes and compromised homes continues to widen.

For buyers, understanding which streets, aspects and planning overlays truly protect value is critical. This is where working with an experienced Mosman buyers’ agent can make a meaningful difference
