Cotality's September index, published on 1 October, put Sydney dwelling values down 7.0% over 12 months. Nationally, values fell 1.1% in September, the sixth monthly fall in a row, and sit 5.2% below the March peak. Those are real figures. They are also not figures for the Central Coast, and I will not pretend otherwise. This article sets out what the numbers say, what they cannot say about our suburbs, and how I would use them if I were deciding whether to sell.
Key points
- Sydney dwelling values are down 7.0% over 12 months to September (Cotality), and national values have fallen six months in a row.
- The most current Central Coast figure I could find is for the Wyong area: up 1.3% over 12 months. I found no reliable figure for Gosford, Erina, Kincumber or Terrigal.
- A median blends house types and is a poor guide to pricing your own home.
The headline numbers
Cotality reported national values down 1.1% in September, unchanged over 12 months and 5.2% below the March peak. Sydney fell 1.4% in the month and 4.9% over the quarter. It is down 7.0% over 12 months, with a median value of $1,198,596 across all dwellings, and sits 8.6% below its February peak. That Sydney median covers houses and units together, so it says little about any single street.
Why the national and Sydney figures differ
National values are flat over the year, but Sydney is down 7.0%. A national figure blends capital cities with regional areas, and different places move at different speeds. Sydney is large, expensive and sensitive to borrowing costs, so rate rises tend to show up there early. The lesson is that no single number describes a market. Each one answers a narrower question than its headline suggests.
Why Sydney matters on the Coast
Many Central Coast owners and buyers have a Sydney link: work, family, or a home they sold to move north. When Sydney confidence and borrowing capacity change, some of that reaches the Coast. How much, and how fast, differs by suburb and by property type, and I have not found published data that measures it for the suburbs I work in.
What the Wyong figure does and does not say
The most current Central Coast number I could find from Cotality is for the Wyong area, in the northern part of the region: a median of $915,725 and growth of 1.3% over 12 months to 30 September 2026. It says the northern Coast has not followed Sydney down over the year. It says nothing about East Gosford, Erina, Kincumber or Terrigal, which are different markets with different buyers. I have not found a reputable current median for those suburbs, so I am not going to quote one. If you see a confident figure for your suburb, ask where it comes from and what period it covers.
How to read a median
A median is the middle sale in a period. It mixes houses, units and townhouses, waterfront and inland, renovated and original. It describes sales that have already happened, not what a buyer can choose from this week. Use it for direction, not for pricing your home.
Three questions to ask of any price figure
- What period does it cover? A monthly fall and a 12-month change can point in different directions, as the national numbers above show.
- What does it include? Houses and units together behave differently from houses alone.
- How many sales sit behind it? A small suburb with few sales can swing sharply on a handful of results.
The mistakes I see in price news
- Anchoring on the peak. Being 5% below a peak is not the same as being worth 5% less than your neighbour paid last year.
- Treating a city figure as a street figure. Sydney's 7.0% fall says very little about a particular home in a particular Central Coast street.
- Waiting for a headline to turn. By the time a recovery is reported, buyers have often already moved.
What this means if you plan to sell
Treat the Sydney figures as a mood indicator, not a price for your home. What decides your result is the evidence closest to you: sales of genuinely comparable homes, what is currently for sale nearby, and how your property presents against both. A broad fall in a distant market does not stop a well-priced, well-presented home attracting offers, and a flat headline does not rescue one that is priced above the evidence.
What I will be watching next
- The RBA decision on 3 November.
- Cotality's next monthly index, due in early November.
- The Domain September-quarter report, which had not been published when I checked on 12 October.
Each will add or remove a piece of the picture. None will replace comparable sales for your street.
Property type changes the answer
A suburb figure blends houses, units and townhouses, and they do not move together. On the Coast a villa near East Gosford's village, a family house on a larger block in Springfield and a waterfront-positioned home in Saratoga draw very different buyers. A broad fall or rise tells you little about which of those you own.
What buyers tend to do in a market like this
When prices are flat or falling, buyers usually take more time. They inspect more than once, ask for building and pest reports before they bid, check that their finance approval is current, and compare against what else is listed. A seller who expects a quick, emotional decision may be disappointed. One who has answers ready usually is not.
What you can do to strengthen the evidence for your home
Gather what a buyer will ask for before they ask: council and plan information, records of any work done and the approvals for it, recent building and pest reports if you have them, and a list of what is included in the sale. Evidence of a well-kept home supports your price better than any suburb headline.
Why I use one source and name it
When I looked for Central Coast figures, one aggregator site published a Wyong house growth figure that conflicts with Cotality's. When sources disagree, I use the one that explains its method and its date, and I say what I could not confirm. That is why this article quotes one Wyong figure, not two.
Questions owners ask
Are Central Coast prices falling?
I cannot say from reliable published data for the suburbs I work in. The northern Coast figure from Cotality was up 1.3% over 12 months to 30 September, while Sydney was down 7.0%.
Should I wait for a recovery before selling?
That depends on your reasons, your loan and your next purchase. Waiting has costs as well as possible benefits. My checklist for owners walks through both.
How do I find the median for my suburb?
Check Cotality, Domain or PropTrack reports, and read the period, the property types included and the number of sales behind the figure. An agent can also explain what sits behind a number.
How I price when local data is thin
My approach is to build the case from the ground up. I find the comparable sales that match on property type, land, accommodation, condition and position, then look at what buyers can choose from now, and only then decide a price range. If the evidence is thin, I say so and explain what is missing, rather than filling the gap with a confident number.
Sydney is a useful warning light. Your street is the evidence that counts. If you want that evidence for your home, request a free appraisal, compare the Central Coast suburb reports, or read what four rate rises mean for Central Coast owners.
