It is not what I think your property is worth. It is what the market will pay. Understanding the difference is the single most useful thing a seller can do.
Few things cause more confusion than property value. Online estimates say one number, the neighbour’s sale suggests another, and the suburb median tells a different story again. None of them is the answer. This guide explains how value is really set, why estimates vary so widely, and why some homes sell well above their suburb’s average while others sell below.
Automated estimates from property websites are built from broad data: past sales, suburb trends and general patterns. They cannot see inside your home. They do not know about the renovation you completed, the aspect of the living room, the quiet position on the street or the work still to be done. That is why two estimates for the same home can differ by a wide margin, and why a confident looking number can be well off the mark in either direction.
They are a useful starting point for orientation, nothing more. They are not a valuation, and they are not what a buyer will pay.
A suburb median is simply the middle figure of recent sales. It blends unrenovated cottages with rebuilt family homes, busy roads with quiet streets, and small allotments with large ones. Your home is not the median. It sits somewhere above or below it depending on its own qualities.
This matters in the Eastern Suburbs in particular, where a single street can hold original homes and architect rebuilds side by side. The median describes the suburb. It does not describe your property.
Buyers do not value a home with a spreadsheet. They compare it against the other homes they have seen and ask a simple question: is this better or worse, and by how much? Value is set by that comparison, in real time, by real people with their own needs and emotions.
The factors that shape it are consistent:
Value is rarely set by one buyer in isolation. It is set when several buyers want the same home and respond to one another. A home with three interested parties will almost always achieve more than the same home with one, regardless of any opinion about what it “should” be worth.
This is why presentation, pricing and the method of sale matter so much. Their job is to bring genuine buyers together in the same window. Get that right and the market itself sets a fair, often strong, result.
Value does not sit still. Interest rates, buyer confidence, the number of homes for sale and the time of year all shift what buyers are willing and able to pay. The same home can achieve different results in different conditions, through no fault of the home or the owner.
That is why a current, local read matters more than last year’s sale down the road. If you would like to understand how shifting conditions change strategy, see Selling In A Changing Market.
Some homes consistently sell above what the suburb data would predict. Usually it comes down to a combination of things done well: genuine presentation, a position or feature buyers prize, accurate pricing that invites competition rather than deterring it, and a campaign that reaches the right buyers. None of it is luck. It is the result of good decisions made in the right order.
A market appraisal is an agent’s informed opinion of your likely selling range; a valuation is a formal, certified figure from a licensed valuer, usually for finance or legal purposes. They’re not the same thing — here’s a full breakdown of appraisal vs valuation and which one you actually need.
The honest answer is a range, not a single figure, and it depends on your specific home, its condition and current buyer demand. A current market appraisal looking at comparable local sales will give you a realistic range. It is not what I think it is worth that matters, it is what the market will pay.
Online estimates are built from broad data and cannot see inside your home or judge its position, condition or appeal. An appraisal considers the things that actually move a buyer. The two will often differ, sometimes significantly.
Not usually. Overpricing tends to deter the very buyers who would compete for a home, leaving it to sit on the market and often sell for less in the end. Accurate pricing that invites competition is far more likely to produce a strong result.
