The graph traces the past 12 months of index values for each of the major capital city and combined capital city dwelling markets. The graph is updated daily and provides a rolling 365 day view of how dwelling values have changed based on the Cotality Daily Home Value Index.

On the 1st day of each month the daily back series will revise for the past 12 months in line with the revision across all of Cotality's Hedonic Indices. Because data from the most recent month is already up to date, it will not shift, but the 11 months prior will experience some revision.

Methodologies

Understanding our methodology

Understand the Hedonic Regression Model behind our home value indices.

This methodology seeks to overcome theissue of compositional bias associated with median price and repeat salesmeasures. The premise for this lies in hedonic theory which says that the valueof a composite good, such as a house, is the sum of its components. Thus, byseparating the sample of houses into their various structural and locationalattributes, the differences in these qualitative factors across houses can becontrolled.

Hedonic imputation is a method ofimputing the value of dwellings having a certain set of characteristics (but nocurrent sales price) by observing the sales prices and characteristics of otherdwellings that do have recent sales prices.
