Choosing an investment property based on recent price growth can be tempting. But yesterday's strongest-performing suburb isn't necessarily where the best opportunity sits today.
For investors considering living on the NSW South Coast or Canberra, the more useful question is: what does the data tell you about the forces that could drive demand over the years ahead?
Good property research starts well before comparing individual houses. It means examining the economy, population, employment, infrastructure and future housing supply before drilling down into suburb-level indicators and, eventually, the property itself.
Here are some of the key numbers I look at when researching property investment opportunities for iStrategic clients.
Start With the Bigger Property Market Fundamentals
There are short-term property market cycles, and then there are long-term fundamentals.
I think about market cycles as waves and the underlying fundamentals as the tide. Waves can create significant short-term movements, but the direction of the tide has a much greater influence on where you ultimately end up.
That distinction matters when researching markets across areas such as the NSW South Coast and Canberra. Instead of starting with the suburb that has recently recorded the strongest capital growth, I first want to understand the broader city, region or Local Government Area (LGA).
1. Local Economic Growth
One of the first numbers I examine is Gross Regional Product (GRP).
GRP can help investors understand the size and direction of a regional economy. I look at how the local economy has performed over several years and, where reliable projections are available, its outlook.
Ideally, I want to see resilience and consistent economic growth. Growth above state or national averages can be encouraging, but it isn't an absolute requirement.
LGA-level economic and industry data can be researched through sources such as .id, alongside information published by local council websites.
2. Industry Diversification
The headline economic growth number doesn't tell the entire story. Investors should also understand where local employment and economic activity come from.
An area supported by industries such as healthcare, education, construction, government, professional services, manufacturing and logistics generally has a different risk profile from an economy heavily dependent on a single industry.
This is particularly relevant when comparing different NSW South Coast markets with Canberra. The economic and employment drivers of individual locations can vary considerably, which is why investors should investigate the underlying industry mix rather than treating every regional market the same way.
3. Population Growth
Property ultimately comes back to supply and demand.
Growing populations need somewhere to live, but the headline population number is only the beginning. I want to know:
- How quickly has the population been growing?
- Where are new residents coming from?
- Is growth driven by overseas migration, interstate or intrastate migration, or natural increase?
- What is the projected population over the coming years?
The Australian Bureau of Statistics (ABS) and .id are useful starting points for investigating population and migration trends.
For investors, the objective isn't simply to find the fastest-growing population. It is to understand whether population growth is sustainable and how that demand interacts with the available housing supply.
Look Beyond the Big Infrastructure Headline
Infrastructure investment can be another important part of property market research, but investors need to look beyond announcements.
Public investment might include hospitals, defence facilities, highways, rail infrastructure and schools. Private investment can include manufacturing facilities, logistics hubs, renewable energy projects, major retail developments and private education.
What matters isn't simply finding one large project.
I prefer to identify a weight of investment capable of supporting employment and economic activity over many years.
Hospitals, defence and education projects can be particularly interesting because they may create employment during construction while also supporting ongoing jobs once operational.
For NSW South Coast and Canberra property investors, council websites, government project information and regional economic data can help build a clearer picture of the investment pipeline.
Future Housing Supply Can Change the Equation
Strong population growth isn't necessarily enough to make an area attractive.
You also need to know how much housing is being built.
Building approvals, commencements and completions can provide insight into the future supply pipeline. ABS construction and housing data is one source I use when assessing these trends.
Consider two hypothetical markets experiencing similar population growth. One has a substantial pipeline of new houses and apartments under construction. The other has limited new housing supply.
Those two markets could experience very different supply-and-demand conditions.
When population and employment are expanding while housing construction remains constrained, it can create the type of imbalance worth investigating further.
Then Zoom In to Suburb-Level Property Data
Once I'm comfortable with the broader fundamentals, the research becomes much more granular.
This is where I look at indicators including vacancy rates, property listings, sales volumes, days on market and rental growth.
As general benchmarks, I tend to prefer:
- Vacancy rates below 2%
- Inventory of approximately three months or less
- Days on market below 30 days
These aren't rigid rules. More importantly, today's number should be considered alongside the trend.
A vacancy rate might look acceptable in isolation, for example, but investors should also ask whether it has been rising or falling.
Sources including SQM Research, Cotality and Hotspotting can help investors investigate these local property market indicators.
Why Sales Volumes Can Matter More Than Recent Price Growth
Sales volumes are one metric I watch particularly closely because they can provide an early indication of changing demand.
Increasing transaction volumes can indicate strengthening buyer activity before that demand is fully reflected in property prices.
Capital growth, by comparison, is one of the more lagging indicators available to investors — yet it is often the first number people look at.
Rather than asking, "Which suburb increased the most last year?", I prefer to ask, "What conditions are developing that could support future performance?"
Capital growth is ultimately the result of numerous underlying forces, including supply, demand, population, employment, borrowing conditions and buyer competition.
Finally, Analyse the Individual Property
Strong regional and suburb data doesn't automatically make an individual property a good investment.
At property level, comparable sales and comparable rents become critical.
The purchase price should be supported by genuine comparable transactions, while the expected rental income should make sense against actual local leasing evidence.
Platforms including realestate.com.au, Domain, Allhomes and PropertyValue can assist with property-level research and comparable evidence. Landchecker can also provide useful information on zoning, site characteristics and other property-specific factors.
The property itself should also match local tenant and owner-occupier demand.
A dwelling near a major hospital, university or employment precinct may need to appeal to a different demographic from a house in a family-oriented outer suburb. The goal is not simply to buy a technically good property. It is to buy the right type of property for the people who actually want to live in that location.
Don't Ignore Property-Specific Risks
Before making a final decision, investors also need to overlay potential risks.
These can include flood exposure, bushfire risk, local crime and concentrations of social housing, among other location-specific factors.
This stage can be particularly important when assessing different NSW South Coast locations, where environmental risks can vary significantly between suburbs and even individual streets.
It is another reason property research should eventually move from national and regional statistics right down to the individual site.
You Don't Need a Perfect 10 Out of 10 Investment
In reality, finding an investment that ticks every possible box is extremely difficult.
For iStrategic clients, I'm generally looking for what I would describe as an 8-out-of-10 opportunity: strong underlying fundamentals, compelling local indicators, manageable risks and a purchase price that still represents value while producing an appropriate rental yield.
If a market looks like a 10 out of 10 to everybody, there's a reasonable chance many of those advantages are already widely recognised.
The opportunity can instead be in identifying improving conditions earlier — before simply following recent capital growth.
And there is another major set of numbers investors need to consider: cash flow, including gross and net rental yield. That's an important topic in its own right and one we'll explore separately.
Make Property Decisions Based on Evidence, Not Headlines
Whether you're researching Canberra or the NSW South Coast, or elsewhere, property investment decisions shouldn't rest on a single statistic.
Economic strength, industry diversification, population, infrastructure, housing supply, vacancy rates, sales activity and property-level evidence all help build a more complete picture.
That's the research and property selection process at the heart of what I do for iStrategic clients.
Good property investing isn't simply about predicting the next wave. It's about understanding which way the tide is moving.

Frequently Asked Questions
1. What property data should I look at before buying an investment property?What property data should I look at before buying an investment property?
Start with the broader economy, population growth, employment and industry diversification, infrastructure investment and future housing supply. Then investigate suburb-level vacancy rates, listings, sales volumes, days on market and rental growth before analysing comparable sales, rents and risks for the individual property.
2. What is a good vacancy rate for an investment property area?
As a general research benchmark, I prefer vacancy rates below 2%. However, investors should also examine the direction of the vacancy-rate trend rather than relying on a single figure.
3. Is recent capital growth a good way to choose an investment suburb?
Recent capital growth provides useful historical information, but it is a lagging indicator. Investors should also investigate the underlying factors that could influence future demand, including population, employment, housing supply, transaction volumes and rental conditions.
4. What should I research when investing on the NSW South Coast?
Look at the fundamentals of the specific South Coast market you're considering rather than treating the region as one property market. Examine population and employment trends, industry diversity, infrastructure, future housing supply and environmental risks before drilling down to suburb and property-level data.
5. What data should I consider when buying an investment property in Canberra?
Canberra investors can use the same framework: analyse the broader economy and employment base, population trends, infrastructure and housing supply before examining suburb-level vacancy rates, inventory, sales volumes, rental performance and individual property comparables.
