15 SPEEDWELL CLOSE 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 two 15 SPEEDWELL CLOSE sales from September 2006 and September 2022 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 September 2006 sale was for 10% above the HPI. So the extrapolation line tracks at 10% above the HPI over time, until the September 2022 sale, where it falls to 3% above the HPI.
