R|O RatioScaleStore Reports, LGA PagesRenter to Owner Ratio is the proportion of Renter households to the Owner Occupier or Mortgagee Households. The higher the number, the more renters there are relative to owner occupiers.

U|H RatioScaleStore ReportsUnit to House Ratio is the proportion of total unit dwellings to that of houses in the area. Calculated by apportioning the number of units sold in the last 2 years to that of houses. The higher the number, the more units there are relative to houses.

Frequently Asked Questions

How do I get the HtAG Market Insights data?

1. Download a report from the HtAG Store.
2. Unzip the html file and open it.
3. Apply filters and/or toggle additional columns as required.
4. Export to CSV file using the export button in the middle.
5. Open the exported file using Excel or another spreadsheet software.

Export buttons can be found at the bottom of the downloaded html file and look like this:

How do I prepare the downloaded data for property market analysis?

1. Format the columns in the spreadsheet based on their data type i.e. currency, percentage or number.
2. Apply “Text to Columns” feature to scale metrics i.e. R|O and U|H Ratios using the pipe symbol (|) as a separator.
3. You will then need to apply number filters to metric columns based on the ranges defined on this page.

Note that percent column filters should be typed in as decimal points i.e. 3% will be “less than” or ” more than” 0.03.

How do I shortlist suburbs based on supply and demand metric ranges?

The starting point should be to shortlist suburbs by filtering out Unfavourable, Low Demand and High Supply markets. The resulting list is then up to you to work through by applying additional filters based on property market metrics of your choice, whilst also gauging the potential Capital Growth and ROI based on provided data.

The more metrics fall into the Favourable, High Demand, Low Supply bands for a particular market, the more likely it is that Capital Growth will be towards the high range of the forecast. Be mindful that Neutral/Balanced markets frequently provide great outlooks and should not be discounted from research.

How did you establish the High / Balanced / Low and the Unfavourable / Neutral / Opportune ranges?

The ranges are determined by data distribution for every metric with 25th and 75th quantiles serving as cut offs between the 3 bands. Note that the data distribution is reflective of the current market conditions. Whereas generic metrics such as R|O Ratio have a constant distribution and ranges, Demand and Supply ranges are subject to change. Given that the ranges are established based on data for the past 3 months, they can migrate up or down as new data is collected between data releases.

Why is the HtAG reported metric value different from another provider i.e. SQM?

When comparing the data from two or more data providers it is always important to ensure that the providers use the same data curation method. If the method is different, then the property market metric values will most likely also be different.

For example, differences in the HtAG Vacancy Rate and that reported by SQM can be explained by different reporting period. HtAG reports it for the rolling quarter (3 months), whereas SQM reports it for the fixed month period.

We are working on a change that will report vacancy rates for the relevant market segment i.e. houses or units. Currently Vacancy Rates are reported for these segments jointly by all data providers.

Why did a metric value increas or decrease since the last data release?

Most metrics are known to fluctuate at the suburb level quite notably between data releases. For example, a change in Vacancy Rate from 2.4% to 2.0% is not significant. This fluctuation is not because the rates are changing, but because of the sparsity in the underlying data, which results in data noise between updates. That’s why the rates should always be ball-parked against a wide enough range.

Why did the Capital Growth and Total ROI values change since the last data release?

As HtAG projections are based on a forecast algorithm, which caries a degree of uncertainty, the CG (Capital Growth) values should be treated as an estimate of the general trend in the rate of growth and not as an exact percentage value. Note that changes of up to plus or minus 3% in CG and all other property market metrics are normal between data releases. Changes in low and very low confidence suburbs can be higher than 3%. This is due to the underlying data sparsity at the suburb level.

Although changes are common between data releases, we find that fluctuations in the reported data even out over time. This is another reason why the values should be treated as ballpark ranges and not exact figures.
