17 GERDDI TAF Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cardiff local authority area over time, sourced from the HPI. The three 17 GERDDI TAF sales between June 2002 and May 2025 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the April 2006 sale was for 32% above the HPI. So the extrapolation line tracks at 32% above the HPI over time, until the May 2025 sale, where it rises to 33% above the HPI. The line then continues to track at 33% above the HPI.
