Is this price reasonable?
How to sanity-check a specific listing or sale price using real comparable sales and suburb context — the method professional valuers use, not a black-box number.
Key points
- A suburb median describes the whole suburb, not any one property — it can't tell you whether a specific listing or sale is priced fairly on its own.
- Professional valuers primarily use the sales comparison approach: comparing a property against genuinely similar properties that have actually sold recently.
- Only a confirmed, settled sale price reflects what a real buyer actually paid — an asking price or online estimate hasn't been tested by the market yet.
- LANDATA, Victoria's official land information service, sells reports showing real comparable sale prices for a specific property or nearby similar properties.
- A price that looks like an outlier usually has a real, identifiable reason — a bigger block, development potential, or auction competition — not a mysterious one.
The question a suburb median can't answer
"Is this a good price?" is one of the most common questions a buyer asks about a specific listing or a sale they've just seen — and a suburb median genuinely can't answer it. A median describes every house or unit that sold across an entire suburb, in every condition, on every kind of block (Valuer-General Victoria / Land Use Victoria, verified 29 Jul 2026); it was never built to tell you whether one specific address, with its own condition, land and features, is priced fairly. Confusing the two is the single most common mistake in this kind of research — comparing a specific listing directly against the suburb-wide average, rather than against genuinely similar properties.
The method professional valuers actually use
Professional valuers primarily use the "sales comparison approach" — estimating a property's value by comparing it against genuinely comparable properties that have actually sold, then adjusting for real differences between them (Australian Property Institute, verified 21 Aug 2026). You can apply the same logic yourself, at a more general level, without a formal valuation. A genuine comparable sale shares the essentials: the same property type (house vs. unit vs. townhouse), a similar land size or floor area, a similar condition and standard of finish, and — importantly — it actually sold recently, not just listed. A single comparable tells you very little; look for several, and be honest with yourself about how closely each one actually matches, rather than picking the one that supports the number you were hoping for.
Confirmed sale prices, not asking prices
An asking price, an "offers over" figure or an online estimate hasn't been tested by the market yet — only a confirmed, settled sale price tells you what a genuine buyer actually paid. Victoria's own underquoting laws exist precisely because advertised price guides can understate what a property is likely to sell for, with real penalties for an agent who breaches them (Consumer Affairs Victoria, verified 30 Jul 2026) — see understanding price guides for the full detail on reading an asking price honestly. For Victorian sales that become unconditional on or after 1 October 2026, the selling agent must also publish the sold price on the listing's Property Price Statement within 7 days and keep it public for at least 18 months, with limited exceptions (Consumer Affairs Victoria, verified 27 Sep 2026). For comparable sales specifically, LANDATA — Victoria's official land information service — sells sales-history reports covering a specific property's past sale prices, and a Rates Objection report covering sales for similar nearby properties over the surrounding 12 months, the same evidence the Victorian government itself requires to formally object to a council rates or land tax valuation (LANDATA (operated by SERV, Victorian Government), verified 21 Aug 2026).
Use the suburb's own data as a backdrop, not a verdict
Delora's own suburb pages give you real, sourced context to sanity-check your comparable sales against: the current median, recent growth, and — critically — how many sales that median is based on (see sales volume and market depth for why that count matters). If your comparable sales all cluster well above or below the suburb median, that's worth a second look — either the property type or pocket you're comparing against genuinely commands a premium or discount, or one of your "comparables" isn't as comparable as it looked.
When a price looks like an outlier, there's usually a real reason
A price that looks well above what comparable sales suggest usually has a genuine explanation, not a mysterious one: a larger or better-positioned block, real development or renovation potential a simple comparison misses, a feature (a view, a particular street) the comparable sales don't share — or, very commonly at auction, competition and emotion pushing the result past what the evidence alone would predict. None of that means the comparable-sales method failed; it means that specific result had a specific cause, and it's worth identifying which one before assuming the whole market has simply moved.
Common mistake: comparing a specific listing or sale directly against the suburb median, rather than against a small number of genuinely similar recent sales — and treating an asking price as if it were a confirmed, settled sale price.

Frequently asked
Can Delora just tell me if a specific listing is a good price?
No, deliberately. Delora's own suburb-level fair-value model is transparent about its limits — see why online property estimates never agree — and doesn't extend to individual properties. This page teaches the method professional valuers actually use (comparable sales) so you can apply it yourself, rather than adding another black-box property estimate to the pile.
Why can't I just compare a listing to the suburb median?
A suburb median describes the whole suburb across every property type and condition, not one specific listing. A genuine comparison needs sales of similar properties — similar type, size and condition, sold recently, nearby — not the suburb-wide average of everything that sold.
Where do I actually find real comparable sales, not just listing prices?
Confirmed sale prices, not asking prices, are what matter — a listing's asking price hasn't been tested by the market yet. LANDATA, Victoria's official land information service, sells sales-history reports showing actual settled prices for a specific property or for similar nearby properties, the same evidence the government itself requires to formally object to a council valuation.
A sale price looks way higher than I'd expect — what usually explains that?
Common, genuine explanations include a larger or better-positioned block, renovation or development potential a straightforward comparison misses, or — very commonly at auction — buyer competition and emotion pushing a price past what the comparable evidence alone would suggest. None of these mean the comparable-sales method was wrong; they mean that specific sale had a specific reason to be an outlier.
Practical checklist
Before deciding whether a price looks reasonable
- Find several genuinely comparable sales — similar type, size and condition, sold recently, nearby
- Use confirmed settled sale prices, not asking prices or online estimates
- Check the suburb's median and how many sales it's based on as a sanity-check backdrop
- If a price looks like an outlier, look for a specific reason before assuming the market has moved
- Get a professional valuation before relying on any figure for a decision involving real money
Questions for a professional
- Based on genuinely comparable recent sales, does this asking or sale price look reasonable?
- What in this specific property explains any gap from the comparable sales — land, condition, position or something else?

Important limitations: This teaches a general method for sanity-checking a price against comparable sales — it is not a valuation of any specific property and doesn't replace one. Delora doesn't estimate or endorse a value for any individual listing or sale. For a decision involving real money — an offer, a loan, a purchase — get a professional valuation, not just a comparable-sales sanity check.
