# The Software Buyers Agents Use to Pick Suburbs. I Am Showing You For Free.

*By Yan Zhu, Co-Founder & Chief Data Officer at PremiumRea — 2023-01-23*

> I am genuinely tired of watching buyers agents charge $20,000 to sit at a desk and click through a piece of software. So I am going to show you exactly how they do it. Every filter. Every metric. Every shortcut. If you learn this, you can replicate half of what a buyers agent does for free.

I am genuinely tired of watching buyers agents charge $18,000 to $22,000 to sit at a desk and click through a piece of software. So I am going to show you exactly how they do it. Every filter. Every metric. Every shortcut.

This might cost me some friends in the industry. Frankly, I do not care.

The software is called HTAG, and it is the backbone of data-driven suburb selection across the Australian property industry. Most buyers agents will never tell you it exists because the moment you understand how to use it, their mystique evaporates. They are not geniuses. They are people who know how to operate a dashboard.

I am not saying buyers agents are worthless. The good ones add value in negotiation, off-market access, and risk identification that software cannot replicate. But the suburb selection piece? That is a learnable skill, and I am going to teach it to you right now [1].

## What HTAG actually does (and what it does not do)

HTAG aggregates property data from multiple sources: the ABS census, state valuation authorities, rental databases, and historical sales records. It lets you filter and rank suburbs across dozens of metrics.

What it does well: quantitative screening. You can filter 15,000 suburbs across Australia down to a shortlist of 20 in about ten minutes. Affordability ratios, growth rates, vacancy rates, population density, dwelling composition. All of it is sortable and filterable.

What it does not do: tell you whether a specific property is worth buying. HTAG identifies suburbs, not properties. It cannot tell you that the house at 14 Smith Street has rising damp, that the neighbours run a panel-beating workshop from their garage, or that the easement cuts through the only spot where you could build a granny flat. That is where fieldwork and due diligence come in [2].

Think of HTAG as the funnel. It narrows 15,000 options down to 20. Then you need boots on the ground to narrow 20 down to one.

## Step one: set your non-negotiable filters

Start with the filters that eliminate entire suburbs before you look at a single data point.

Affordability ratio: I set a maximum of 10 times median household income. Anything above 10 means the suburb is pricing out most buyers, which slows growth unless overseas capital keeps flowing. For investment-grade suburbs in the $600,000 to $800,000 range, you typically see affordability ratios of 7 to 9 [3].

Owner-occupier ratio: minimum 60 per cent. I prefer 70 per cent or above, but 60 per cent is my hard floor. Below 60 per cent means the suburb is renter-dominated, which correlates with weaker capital growth and higher turnover.

Vacancy rate: maximum 2.5 per cent. Below 2 per cent is ideal. Above 3 per cent is a red flag that supply is outpacing demand [4].

Unit proportion: maximum 30 per cent. Above 30 per cent and apartment supply is diluting the scarcity premium on houses. This filter alone eliminates suburbs like Doncaster (47 per cent units) from an investment shortlist.

These four filters typically reduce your suburb universe from 15,000 to about 300.

## Step two: rank by growth and yield metrics

Once you have your filtered list, sort by the metrics that matter for your strategy.

For capital growth investors: sort by ten-year median house price growth. I look for a minimum of 50 per cent over ten years, which equates to roughly 4.1 per cent compound annual growth. Anything above 70 per cent puts the suburb in the top quartile nationally.

For cash flow investors: sort by gross rental yield. I look for suburbs where the median yield is above 4 per cent. In Melbourne, that typically means you are looking at the outer southeast, Geelong region, or regional Victoria. Suburbs like Doveton, St Albans, and the Cranbourne corridor regularly hit this threshold after light renovation [5].

For balanced investors: I use a composite score that weights growth at 60 per cent and yield at 40 per cent. This tends to surface suburbs in the $600,000 to $750,000 range with moderate growth and above-average yield potential.

Days on market is your urgency indicator. If a suburb has strong fundamentals but properties are sitting for 40-plus days, there is a demand issue that the aggregate data is not capturing. Conversely, if days on market is below 20, you need to be prepared to move fast because every other data-literate buyer has identified the same opportunity.

## Step three: cross-reference with on-the-ground reality

This is where most data-only investors get burned. HTAG tells you that a suburb looks good on paper. It does not tell you what the streets actually feel like.

I have seen suburbs with perfect HTAG metrics that are genuinely unpleasant to live in. Industrial noise, poor streetscaping, lack of tree cover, social housing clusters that create pockets of antisocial behaviour. None of this shows up in a database.

Conversely, I have seen suburbs with average HTAG metrics that are quietly gentrifying. New cafes opening, young families replacing retirees, council investing in parks and streetscaping. These suburbs are about to show up in the data, but by the time they do, the opportunity window has narrowed.

Our process at PremiumRea involves driving every suburb on our shortlist. Not once. Multiple times. Morning, afternoon, weekend, weeknight. You learn more about a suburb sitting in your car at 10 PM on a Thursday than you learn from a hundred spreadsheets [6].

The data gets you to the neighbourhood. Your eyes and ears tell you whether to buy in it.

## Why I am giving this away for free

Because the software is not the moat. The moat is everything that comes after the software.

Negotiating $30,000 to $50,000 off the asking price. Identifying structural defects that the building inspector missed. Knowing which selling agents will call you back and which ones will ghost you. Understanding council planning overlays well enough to predict whether a granny flat application will sail through or get rejected.

That is the 80 per cent of a buyers agent's value that no software can replicate. The suburb selection piece is maybe 20 per cent. I am giving you the 20 per cent so you can make an informed decision about whether the other 80 per cent is worth paying for [7].

Across our 350-plus transactions, the average client saves $35,000 to $50,000 through our negotiation process alone. That is two to three times the service fee. The suburb selection is just the starting line.

Download HTAG. Learn the filters. Drive the suburbs. And if you want someone to handle the hard bit, the negotiation, the due diligence, the conversion strategy, you know where to find us.
