CoreLogic indices

Australia's authoritative source on home price trends.

CoreLogic has a high performing and timely suite of world-class property indices that have transformed the way Australian's measure and understand changes in the value of residential real estate.

CoreLogic Indices are available on a daily, monthly and quarterly basis for Australian geographic demarcations that conform with the Australian Statistical Geography Standard (ASGS) as well as non-standard boundaries such as suburbs, postcodes and council areas. These indices draw on the most comprehensive property database in Australia and are computed using some of the most advanced global index construction techniques. Customised versions of CoreLogic Indices are also available.

CoreLogic Indices are constructed from the latest possible property sales information thereby avoiding the 6 to 8 week reporting lags associated with some other published indices.

CommSec's chief economist, Craig James, commented:

"The CoreLogic index has emerged as Australia's authoritative source on home price trends. The property database is Australia's largest and, unlike the Bureau of Statistics, all properties are counted, not just free-standing homes."

Westpac's interest rate strategist, Rory Robertson, commented:

"The CoreLogic monthly estimates are more timely and reliable than the ABS's quarterly readings."

Application

The CoreLogic Daily Home Value Index is useful for any individual or organisation interested in:

Tracking changes in the value of a market portfolio containing all known properties (or any smaller portfolio) due to market value changes (as opposed to changes in composition);

The patented CoreLogic Home Value Index can be produced for various geographic demarcations, from suburb to state or nationally.

It can also be produced across all properties or divided between property types such as units and houses. While the CoreLogic Home Value Index is the benchmark index produced by CoreLogic and defines a new global standard in index construction, there are three “classes” of CoreLogic Indices produced:

The first class of index, known as the “hedonic” model, had not been commercially produced in Australia prior its introduction by CoreLogic. The CoreLogic Home Value Index is a hedonic model. This index utilises comprehensive information on the attributes and characteristics of residential properties (such as location, land size, and bedrooms) to measure “quality-adjusted” changes in property value over time and to also impute the value of dwellings having a certain set of characteristics (but no current sales price) by observing the sales prices and characteristics of other dwellings which have recently been observed as selling.

The hedonic method has the advantage that it utilises attribute (or characteristic) information of each dwelling to mitigate biases that are otherwise prevalent in median and repeat sales property price indices. Another important advantage of a hedonic imputation index is that its calculation frequency can be daily and that it tracks the value of an entire portfolio of property, not just the prices of properties observed to sell in a given period.

The second class of indices CoreLogic have produced are based on a median and “stratified” median price series. Stratification is a process for creating subsets of houses which are qualitatively similar. Unique price series are created for these subsets which are then aggregated to estimate suburb-adjusted price movements in the overall market. The strata definitions used to classify properties into subsets are based on price, geography, land size, and interactions of these variables. The stratified median index that CoreLogic produces for units and apartments, groups suburbs by their long-term median transaction price. The stratified median index that CoreLogic produces for houses groups suburbs by their long-term price to land size ratio.

Median and stratified median indices are simple to calculate and provide the price of the middle ranking property observed to sell in a given measurement period. Further, rather than selecting the 50th percentile (ie, the median) from whatever properties are observed to sell over a particular measurement period, other percentiles such as the 25th or 75th percentile can equally be selected using the same method so as to create other percentile series.

The major shortcoming of median (or any other selected percentile) price series is that they do not represent changes in the value of the residential property market portfolio. Median prices do not track the same properties through time. In fact, it is most unlikely that any of the properties observed selling in one period will be the same as the properties selling in the next measurement period when examining quarterly or monthly median price series. By way of example, in one period the median priced house observed may happen to be a 3 bedroom home and in the next period it may be a 4 bedroom home. Further, in order to provide useful statistics, one needs to aggregate a sufficiently large numbers of property sales over what can be long periods of time. As such, the publication frequency of median price series is often limited to quarterly, although CoreLogic do offer a monthly median series.

The fact that median or other percentile based series cannot be used to track changes in value of a market portfolio does not make them wrong: it is simply that they have different applications than hedonic indices. For example, median price series are useful in answering economic policy questions relating to housing affordability.

The third type of index estimates the performance of the market by analysing the returns on individual properties for which there are at least two observed sales prices, each at different points in time. CoreLogic publish a suite of five different "repeat-sales" indices, all replicating methods in the academic literature.

The first is called the "linear" weighted repeat-sales model (see Case and Shiller (1987)). This was the first repeat-sales model to identify that the dispersion of price appreciation of properties is likely to be related to the time between sales, making explicit adjustments that mitigate the biasing effect of this.

The second and third repeat-sales models, developed by Calhoun (1996) and Webb (1988), extend the Case and Shiller model to allow for “non-linearities” in the relationship between time and return dispersion.

The fourth repeat-sales model of Goetzmann and Spiegel (1995) is motivated by the fact that in many cases the features of properties are not constant through time. The Goetzmann and Spiegel model attempts to controls for elements of price appreciation that are not related to the time between sales (such as the addition of a bedroom) using statistical methods, but, without the use of attribute data to confirm whether there have, or have not, in fact been changes in property attributes. To the extent that a property appreciates faster than other properties, the Goetzmann and Spiegal model is likely to assume its appreciation is as a result of a non-temporal change such as a renovation.

The fifth repeat-sales model is based on the seminal paper of Bailey, Mourse and North (1967).

Repeat sales indices seek to control for changes in the composition of properties selling in different periods without requiring any property attribute data (other than address). They do this by only examining properties which have two separate sales records.

The disadvantage of repeat sales indices is that: (i) they only cover between 30% and 50% of the properties in a given city; (ii) new properties cannot be accounted for (and neither can old properties for which there is no prior sales information on record); (iii) improvements to properties cannot be explicitly accounted for; (iv) there is potential significant sample selectivity bias toward more frequently traded properties (eg, apartments or lower value homes may trade more or less frequently than higher value homes); and they substantially revise through time.

The hedonic regression model is a method used to calculate the patented CoreLogic Home Value Index.

This methodology seeks to overcome the issue of compositional bias associated with median price and repeat sales measures. The premise for this lies in hedonic theory which says that the value of a composite good, such as a house, is the sum of its components. Thus, by separating the sample of houses into their various structural and locational attributes, the differences in these qualitative factors across houses can be controlled.

Hedonic imputation is a method of imputing the value of dwellings having a certain set of characteristics (but no current sales price) by observing the sales prices and characteristics of other dwellings that do have recent sales prices.

Daily indices

The patented CoreLogic Daily Home Value Index is part of the suite of housing market indices produced by CoreLogic. Since the launch of Hedonic Home Value Indices in 2007, CoreLogic established a new quality benchmark for accurately measuring value changes across the Australian housing market.

The CoreLogic Daily Home Value Index aims to measure daily movements in the value of Australian housing markets. Rather than relying solely on transacted sale prices to provide a measure of housing market conditions, the CoreLogic Daily Home Value Index is based on a ‘hedonic’ methodology which includes the attributes of properties that are transacting as part of the analysis.

Understanding factors such as the number of bedrooms and bathrooms, the land area and the geographic context of the property allows for a much more accurate analysis of the true value of movements across specific housing markets. This method also allows for compositional change in consumer buying patterns when measuring capital gains.

The CoreLogic Daily Home Value Index provides daily capital growth measurements for all dwellings, including both houses and units. The index results are released daily for Sydney, Melbourne, Brisbane (including Gold Coast), Adelaide, Perth and the combined capitals, which is a composite of these cities. Historical back series are available on a subscription basis.

The CoreLogic Home Value Index is part of the suite of housing market indices produced by CoreLogic. Since being launched in 2007, the Index has established a new benchmark for measuring value changes across the Australian housing market.

The Home Value Index aims to measure month to month movements in the value of Australian housing markets. Rather than relying solely on transacted sale prices to provide a measure of housing market conditions, the CoreLogic Home Value Index is based on a ‘hedonic’ methodology which includes the attributes of properties that are transacting as part of the analysis.

Understanding factors such as the number of bedrooms and bathrooms, the land area and the geographic context of the property allows for a much more accurate analysis of true value movements across specific housing markets. This method also allows for compositional change in consumer buying patterns when measuring capital gains.

The Home Values Index provides monthly capital growth measurements across three broad housing types: detached houses, units and a combined dwellings index that includes both houses and units. The Index results are released on the last working day of each month and are available on a subscription basis.

Note: On October 1st 2021 Perth’s hedonic indices back series was revised.

CoreLogic’s Unimproved Land Value Index is a measure of the change in underlying land values for detached housing for various geographic demarcations. Unimproved land value (also referred to as Unimproved Capital Value) is the estimated value of the underlying land which a property is built upon, excluding any improvements on the land such as the dwelling itself and other structures (e.g., swimming pools, carports, etc.). This is distinct from the market value of the property which accounts for both the improvements as well as the unimproved land. Leveraging the same hedonic methodology as the Home Value Index, CoreLogic’s Unimproved Land Value Index is derived from a statistical analysis of observed market transactions of residential houses. The model is optimised to control for the contribution of various attributes to changes in observed market sales prices by factoring only the land area and location attributes to the hedonic model (for further details on the model see ‘Methodology’ tab).

Unimproved Land Values are typically used by local councils and state governments to assess various rates and taxes. While each jurisdiction will assess the Unimproved Land Value of individual properties differently, CoreLogic’s Unimproved Land Value Index serves as an additional point of reference for real estate industry observers to monitor how the overall market is changing over time. As CoreLogic’s indices are a statistical assessment of broader market activity, these indices should not be used as a substitute to formal valuations conducted by a registered valuer, and are best used as a supplementary indicator. As commissioned by the respective local councils, CoreLogic has generated the following Unimproved Land Value indices for public reference.
