135 LANSDOWNE ROAD Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Cardiff local authority area over time, sourced from the HPI. The three 135 LANSDOWNE ROAD sales between September 1998 and March 2026 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 November 2010 sale was for 4% below the HPI. So the extrapolation line tracks at 4% below the HPI over time, until the March 2026 sale, where it falls to 22% below the HPI. The line then continues to track at 22% below the HPI.
