Rigorous and regular analytics

Every day, rigorous analytics are run on every residential property in Australia to create a value index. This is headlined by CoreLogic’s Hedonic Home Value Index, which provides the a timely and robust benchmark for assessing the performance of the residential property market. Click here for an overview on our indices.


Leveraging the industry's best practice hedonic methodology, CoreLogic Indices are one of the best measure of housing market performance in the country with full historical trends available dating back to the 1980s. Not only are CoreLogic Indices trusted by regulators and major institutions such as the ASX, Reuters Bloomberg, policy makers and the banking sector, they are built on 30+ years of industry experience on collecting and compiling the broadest and deepest property level information database in the country. 

Features include: 

  • Rigorous hedonic regression method
  • Daily home value indices
  • Indices available on a daily, monthly and quarterly basis
  • Available across capital cities and regional markets by subscription
  • Back series available

Types of Indices

CoreLogic has a suite of world-class property price indices that have transformed the way Australians measure and understand changes in the value of residential real estate. Click here for more information on the types of indices.

There are three different indices:

  1. CoreLogic Hedonic Indices
    Also known as the CoreLogic Daily Home Value Index Construct, this indices is a hedonic model that uses 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. It also imputes 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.
  2. CoreLogic Stratified Median Price Indices 
    The second class of indices is a “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.
  3. CoreLogic Repeat Sales Indices 
    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. 

    Repeat sales indices seek to control 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.

New methodology

On 1 September 2017, CoreLogic released an improved and enhanced methodology behind its Home Value Index. New features include improved sampling, better handling of off-the-plan-sales, dynamic stock weights, model upgrades, updated geographic boundaries and a scalable production environment. Click here for more information.


The outcome of the improvements and enhancements include:

  1. Less volatility in the day-to-day and month-to-month readings without sacrificing capital return estimates.
  2. Longer back series (from 1980 in most areas)
  3. Improved valuation estimates = higher precision in the index results
  4. Full geographical hierarchy of reporting (National through to SA2)
  5. A method that aligns with best practice across Europe and that is endorsed by the IMF and BIS
