40 MOUNTBATTEN CLOSE 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 40 MOUNTBATTEN CLOSE sales between December 2013 and May 2024 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 January 2019 sale was for 40% above the HPI. So the extrapolation line tracks at 40% above the HPI over time, until the May 2024 sale, where it rises to 51% above the HPI. The line then continues to track at 51% above the HPI.
