Know what you're buying.
Independent property intelligence for the moment between finding a home and making an offer. You get a decision, not a data dump.
- What is it really worth?
- What risks should I know about?
- What should I offer?
Our first principle
A property is not a price. It is a set of characteristics.
Two homes at the same asking price can hold entirely different futures. BuyDNA weighs what actually decides the outcome — property value, comparable sales, risks, location, market conditions, rental potential and offer strategy — and shows the evidence behind each one.
- What is this property actually worth?
- Is the asking price realistic?
- What have comparable properties sold for?
- Are there risks I should know about?
- What's happening in this suburb and market?
- What should I consider offering — and when does it stop making sense?
The property's DNA
Seven signals. One clearer buying decision.
Built from property, market and government evidence — and combined into a single BuyDNA Score out of 100.
BuyDNA Score
0–100
The seven signals weighted for how you intend to buy — to live in, or to hold.
ValueDNA
Is the asking price supported by comparable sales, and what does the evidence say it's worth?
GrowthDNA
Long-run price behaviour, supply approvals and how tightly owners hold in this market.
RentDNA
Achievable rent, yield and vacancy — read for the property, not the postcode.
RiskDNA
Flood, bushfire, zoning and condition questions, mapped to the property boundary.
LocationDNA
Measured distances to schools, stations, transport and services from the property itself.
LivingDNA
Size, configuration and liveability — what it's like to actually own and occupy.
DealDNA
Days on market, price changes and competition: how much pressure sits with the vendor.
Each signal is scored only from evidence we could source for the specific property. If a dataset is unavailable, the report says so rather than filling the gap.
The method
Three moves, and nothing hidden in between.
Property decisions are easier when you can see the evidence behind them. BuyDNA shows you the view, the evidence behind it, and how confident the available data allows us to be.

- 01
Enter the property you're considering
Any realestate.com.au or Domain URL. Nothing to fill in, nothing to upload.
- 02
We analyse it against property and market data
Comparable sales, planning overlays, supply pipeline, street character and campaign history.
- 03
You get a decision, not a data dump
What it's worth, whether the asking price is realistic, the risks worth checking, and what to consider offering.

A real Saturday
The listing tells you what they're selling. BuyDNA tells you what you're buying.
You've found a home you love. You love the kitchen, your partner loves the location, and the selling agent says there is strong interest.
But is the asking price reasonable? What have comparable homes sold for? Is there anything you're overlooking? And what should your first offer be?
Below is that same Saturday, read end to end — an illustration of report structure, not a real listing or real market data. Your report is built from data retrieved for the address you enter.

Why we like it
- Quiet no-through family street, 300m from the park edge
- Owner-occupier demand: 78% of recent buyers were live-in
- Inside both a primary and secondary school catchment
What we'd investigate
- Original 1948 electrical system — request a compliance check
- Overland flow path across the rear third; confirm drainage
- Kitchen and wet areas nearing the end of useful life
Leading concern
One bathroom, original kitchen with gas cooking, external laundry and no recorded build year. Budget for a building and pest inspection before you commit.
Where the evidence comes from
Real data, or we say so. Never an estimate dressed as a fact.
Every figure in a BuyDNA report is retrieved for the specific property, attributed to a named source and stamped with the date we pulled it.
Property and market data
Licensed valuation, sales history, comparable sales, rental and market-cycle data for the exact address.
Government spatial and statistics
Flood and bushfire mapping, zoning, schools, transport, health facilities and area demographics, read from official services.
The listing itself
Asking price, campaign history, method of sale and the attributes the agent has disclosed.
Why there is no national market dashboard here
Street resolution
Suburbs are too blunt. We analyse the individual property.
Two houses 300 metres apart can differ materially on resale. Flood lines, arterial frontage, rail noise and catchment boundaries all run mid-street — so hazard mapping, zoning, school and transport distances are read for the individual property, not averaged across a postcode.
Mapped to the property
Flood and bushfire overlays and zoning are queried against the property boundary, then reported with the layer and authority they came from.
Measured, not assumed
Distances to schools, stations, transport stops and hospitals are calculated from the property's coordinates — no suburb-level proxies.
Where a state or council does not publish a layer we can query for an address, the report records the dataset as unavailable instead of substituting a score.
An independent second opinion
Every buyer deserves good property intelligence.
Before one of the biggest financial decisions of your life, you shouldn't have to rely on the listing, the selling agent and a suburb median. BuyDNA is the evidence-based second opinion — not legal, financial or valuation advice, and never a substitute for a building and pest inspection.
