Mosman Property Market Report

Why the Mosman property market may be further through the downturn than the headlines suggest - but the latest rate rise adds another layer of uncertainty.

Read the latest property headlines and you could be forgiven for thinking Australia’s housing

market has only just discovered its brakes. Prices are falling, buyers are cautious and

uncertainty has made everyone feel a little nervous. But according to Mosman real estate

experts, Vernon Partners, Mosman’s story is a little different.

Rather than only now entering the downturn, the local market may already be well into its

correction phase, highlighting the lag between what agents see on the ground and what

eventually appears in broader market data. It comes down to something known as the “filtering effect".

Premium property markets tend to move earlier than the broader market, responding quickly

when conditions change. Higher-value areas can therefore feel a downturn first, before those

declines filter into more affordable markets. The reverse can also happen; premium areas may begin stabilising while prices elsewhere are still falling. And Mosman certainly qualifies as premium territory.

According to Vernon Partners, local house values are currently around 10 to 12 per cent below their previous levels on average, while apartments have experienced a slightly smaller

adjustment. More importantly, the agency believes prices are beginning to stabilise around

these levels. Not every part of the market has followed the same path.

Mosman’s prestige homes have experienced the largest correction, perhaps unsurprising given their premium values. The lower quartile has softened too, but has proved more resilient. One and two-bedroom apartments have been among the suburb’s steadier performers. Their relative affordability - a term that admittedly takes on a slightly different meaning in Mosman - has helped maintain demand, with first-home buyers continuing to compete for quality apartments.

How did we get here?

Vernon Partners traces the beginning of Mosman’s adjustment to mid-to-late 2025, with local

prices down roughly five per cent by early 2026. Since then, higher interest rates, the oil shock and uncertainty surrounding NSW State Significant Development proposals have all contributed to weaker buyer confidence and a more cautious, slower local market. However, the federal budget dealt the final blow. May triggered the sharpest drops as budget changes to negative gearing drove investors to exit.

The latest interest rate rise adds another challenge. On 29 September, the Reserve Bank increased the cash rate by 0.25 percentage points to 4.60 per cent, its highest level since 2011 and the fourth increase this year. The major banks have subsequently announced increases to variable home loan rates.

For property buyers, the effect is straightforward: borrowing capacity remains under pressure

and confidence is harder to rebuild while interest rates are still rising. Yet there is an important distinction to make: slower does not mean stopped.

Properties are still selling and buyers are still active. Transactions are simply taking longer, with purchasers becoming increasingly price-conscious and vendors adjusting their expectations. From Vernon Partners’ perspective, what Mosman is experiencing looks less like a crash and more like an overdue, prolonged price correction.

What happens next?

The latest rate rise makes the next phase less certain.

Vernon Partners expects subdued conditions to continue, with higher borrowing costs likely to keep buyers cautious and some vendors choosing to remain on the sidelines rather than sell below their expectations.

That could keep the supply of quality properties relatively limited, even as the traditional spring selling season gets underway. Limited stock may provide some support for well-priced, desirable properties, but it does not remove the broader pressure created by higher borrowing costs.

For Mosman homeowners, the bigger lesson is that national property headlines don’t always tell the local story.

Real estate markets rarely move neatly in unison, and premium suburbs like Mosman can be

several steps ahead of the broader cycle.

So while falling prices may now be dominating the headlines, locally the more interesting

question is whether Mosman is approaching a new baseline - or whether the latest round of

rate increases will extend the correction before the market finds it.
