# How a Melbourne Buyers Agent Screens Development Sites Every Day: 31 Councils, 500 m², and Why 'Unknown' Is Never 'No'

*By Joey Don, Co-Founder & CEO at PremiumRea — 2026-11-03*

> Every morning we re-read every house listing across metropolitan Melbourne's 31 councils against three tests: land of 500 m² or more, a price inside our candidate cap, and a suburb inside the metropolitan boundary. The part most buyers never see is the third verdict — pending — which is where the best blocks hide.

**Short answer.** Our development-site screen reads every house listed for sale on the public listing portals across the 31 metropolitan Melbourne councils (533 localities, plus a handful of cross-border suburbs), checked daily, applies three tests — land of 500 m² or more, a listed or indicated price inside our candidate cap of $1.2 million, and a suburb inside the metropolitan boundary — and returns one of three verdicts: match, no, or pending. Pending means a fact is missing, usually the land area, and the listing goes into a second pass that reads the land size from the description text and the property's own profile page before anyone is allowed to say no. That one rule is the difference between a buyer who sees the market and a buyer who sees the portal's filter.

This article explains the screen as we actually run it, because a private buyer can copy most of it by hand for the two or three suburbs they care about. What it does not do is publish the listings the screen finds; those belong to our clients.

## What counts as 'metropolitan Melbourne' in the screen?

We use the Victorian planning definition: the 31 metropolitan local government areas, which together contain 533 named localities. A further nine localities straddle the metropolitan boundary and are included by name, and common aliases (old suburb names, duplicated names such as the two Bellfields and two Hillsides, which we tell apart by postcode) are mapped to the official locality.

The reason to be this precise is that the listing portal has no 'Greater Melbourne' search. Its regional search areas, used together, reach 517 of the 533 localities; the remaining sixteen — Sunbury, Wildwood, Whittlesea, Eden Park, Little River, Cambarville and ten Cardinia Shire localities — sit only inside rural search regions and are searched by name. A screen that only ticks the regions whose names sound like Melbourne silently drops Sunbury, every day, forever.

Once a day the screen also re-reads the portal's own membership lists for each search region and compares them against the 533-locality list, so a suburb that the portal moves from one region to another is noticed the day it happens rather than the month a client asks why nothing in that suburb was ever sent.

## The three tests, and why the price test has two doors

**Land.** 500 m² or more. Below that, the rooming-house and two-dwelling products we buy for do not fit once the minimum garden area and a 3 m side driveway are drawn, so the line is a product line, not a market opinion.

**Suburb.** Inside the metropolitan list above. A suburb we do not recognise is not rejected; it is written to a daily review list, because the most common cause is a new estate name that has not yet reached the locality file.

**Price.** This is where most hand-built screens leak. Victorian agents must publish an indicative price, but a large share of listings show no figure at all ('Contact agent', 'Expressions of interest', auction without a guide). Those listings still sit in a hidden search band that the agent sets in the portal back-end, and the portal filters on that hidden band, not on the words on the page. So the screen has two doors: a listing passes if its published price is inside the cap, or if it has no published price but appears in a search capped at the candidate line — which tells us the agent's own hidden band is inside the cap. A listing with a published price slightly above the cap that nevertheless appears in a capped search is passed with a 'please verify' flag, because the agent has either made a typo or is signalling a lower acceptable figure. A listing whose published price is far above the cap but which appears in a capped search is rejected on the published price: we have seen a $2.4 million house sitting in a sub-$800,000 band, and that is a data error, not a bargain.

Since 18 October 2026 the candidate cap for published-price listings in metropolitan Melbourne is $1.2 million. The cap exists to bound the daily workload; the sites that get recommended to clients are a far smaller subset, chosen on same-suburb sale comparables and feasibility, not on price alone.

## Why we never let the portal filter on land size

Every listing portal lets you filter 'land size from 500 m²'. We do not use it, because the filter removes every listing whose land-area field is blank — and in the suburbs we buy in, that field is blank on a material share of listings.

We measured it on 1 October 2026 in Hampton Park, a suburb where we hold a large client portfolio. The filtered search returned 40 houses on 500 m² or more. Without the filter, reading land size from the listing text and the property profile, there were 14 more qualifying listings that the filter had silently dropped — 35 per cent more than the filtered result showed. We opened four of the fourteen: 654 m², 601 m², 786 m² and 646 m². All four were exactly the kind of block the filter was meant to find. Across the metropolitan search regions, somewhere between 16 and 28 per cent of listing cards arrive with no land-area value at all.

So the screen searches on price and dwelling type only and decides land size itself, in this order: first the listing description, accepting a figure only when it sits in a land context ('block', 'allotment', 'land', 'lot', 'site', 'parcel', 'acreage') and ignoring house floor areas, deck sizes, community-park sizes and ranges that describe a whole estate; second, the portal's own property profile page for that address, accepted only when the profile points back at the same listing identifier, because the wrong profile would pin a neighbour's land size onto the listing; third, if neither source answers, the listing stays pending and is retried every three days, up to three attempts, counting an attempt only when it produced a definite answer. A description figure can only move a listing towards 'match' — a small number in the text is never used to reject, because it may describe something other than the land.

## Match, no, pending: the verdict that stops leakage

Most screens have two states: in or out. Ours has three, and the third is doing most of the work.

- **Match** — every fact is known and every test passes.
- **No** — every fact is known and one test clearly fails: land of 420 m², a suburb outside the list, a published price above the cap, a property already sold.
- **Pending** — a fact needed for the decision is missing: the land area is unknown, the price is unknown and the listing did not appear in a capped search, or the suburb could not be resolved. Pending listings are never discarded. They go to the land-size backfill above, they are re-judged the moment a fact arrives, and if the backfill is exhausted they are written to a human review list with the reason.

As Joey Don puts it to new staff: "Not knowing is not the same as not qualifying. Every leak we have ever traced in a buying pipeline was a pending that somebody treated as a no."

'Sold' is also judged strictly from the portal's status badge, not from marketing text. A headline that reads 'Call before it's SOLD!' is a listing, not a sale, and a screen that keyword-matches on the word loses it.

## How we know nothing was missed: the reconciliation step

A search result is paginated and the market moves while you page through it: a listing sold on page three while you are reading page nine simply vanishes, and a listing added at the end appears nowhere. A count that happens to match proves nothing — we have reproduced three distinct ways a page-by-page read can 'add up' and still miss a listing.

So every search region is read in price bands small enough to sit below the portal's hard cap on results per search, each band is read from the oldest listing to the newest and then the first and last pages are re-read, and the number of distinct listings collected in each band is compared to the total the portal reports for that band. The region is only marked complete when every band reconciles and the union of all bands matches a whole-of-region total read at the start and again at the end of the run. If any band fails, the region is marked incomplete for that day, nothing in it is treated as 'withdrawn', and the run is retried. Estates and projects are opened individually, because a project card shows at most five of its lots in search results and the rest exist only on the project page.

None of this is visible to a client, and none of it needs to be. What it buys is a single sentence we can stand behind: if a qualifying house was listed in metropolitan Melbourne and stayed listed for a day, it was in our morning list.

## What a private buyer can copy from this

You do not need software to adopt the habits that matter.

1. **Search without the land filter** in your target suburbs, sort by newest, and read land size from the text and the property profile yourself. Expect roughly one listing in five to need that second look.
2. **Keep a pending column.** Any listing where you could not confirm land, price or title goes there, not in the bin, and you re-check it in three days.
3. **Treat 'no price' as a hidden price.** Run the same search capped at your ceiling; if the listing appears, the agent's own band is inside your budget.
4. **Reconcile.** Note the total the portal reports for your search and count what you actually read. If they differ, something moved and you have a gap.
5. **Only then compare price** — against sold results for the same suburb and the same land-size band over the last twelve months, never against the asking prices around it. That comparison, and the feasibility test that follows it, is the part of our process a buyers agent is paid for; the screen is only there to make sure the comparison is run on every eligible block and not on the subset a filter happened to show.

## How we rank what passes: a 100-point rubric (a ranking method, not a rent forecast)

Passing the three tests puts a block on the list; it does not order the list. Every block that also clears our hard gates — frontage of 15 m or more, a nine-room single-storey footprint of 12.39 × 23.94 m that fits with a 9 m street setback and 1 m to every other boundary and easement, at least two compliant car spaces and the zone's garden area — is then scored out of 100 so a human looks at the best first. The score never decides whether a block qualifies, only the order; below 50 we do not circulate it.

**Price — 40 points.** How far the asking price sits below the twelve-month sold median for the same suburb and the same 100 m² land band (at least eight sales, otherwise twenty-four months): nothing at 0 per cent below, full marks at 25 per cent or more, linear between.

**Demand — 30 points.** The number of rooming houses already registered within 2 km on the Consumer Affairs Victoria public register (10 or more full; 5–9 three-quarters; 3–4 half; 1–2 a quarter), read as evidence that operators have already judged the area, not as a saturation warning.

**Transport and daily life — 30 points.** Half for the nearest train station with at least two services an hour each way (800 m or less full; 1.2 km 0.8; 2 km 0.53; 3 km 0.27; nothing beyond 3 km). One-third for the nearest public hospital with an emergency department on the AIHW MyHospitals list (1.5 km or less full; 3 km 0.7; 5 km 0.3). One-sixth for a bus stop within 400 m with two or more services an hour (0.6 for any stop within 400 m, 0.2 within 800 m). All distances are straight-line from the parcel centroid, so walking distances run longer.

**Risk deductions.** Heritage Overlay −15. Flood overlays (LSIO, SBO or FO) −10. A lot-number-only address −10. Bushfire Management Overlay −5. Erosion Management Overlay −5. Terrain that cannot be read −5; a measured fall across the parcel of 1–2 m −5, 2–3 m −10, more than 3 m −15. Frontage to an arterial road (Vicmap road class 2 or better, or a Transport Zone 2 road, where a new or altered crossover needs a Clause 52.29 permit and referral) −10; 20,000 or more vehicles a day on the frontage road −5; a Public Acquisition Overlay on the frontage −5.

**Access bonuses.** Corner block +15. Side lane +15 or rear lane +15; both +20; corner plus lane capped at +25 — a lane or second street is a mapping observation from Vicmap, not evidence that a crossover will be approved, and most councils require a vehicle-crossing permit. A frequent station within 500 m walking +10, within 800 m +5.

**Grades.** 70 or more is an A, 50–69 a B, below 50 a C. The rubric exists to decide which blocks are worth driving to first; it is not a return on any property, and nothing in it is a rent or a yield.

## What this screen is not

It is not a valuation, a recommendation or a list of bargains. It is the first of several gates, and most listings that match it are rejected at the next gate — a sold-price median for the same suburb and land band, a frontage measurement from the Victorian cadastre, a slope read from state elevation data, a layout test that draws the proposed building and its car parking on the parcel, and a planning check of zone and overlays. Those later gates are described in our other articles on [rooming house car parking and garden area](/rooming-house-parking-victoria-clause-52-06) and [development potential checks](/development-potential-check). The screen's only promise is the modest one above: nothing eligible was missed because a field was blank.
