12 BLACK ROCK ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Monmouthshire local authority area over time, sourced from the HPI. The three 12 BLACK ROCK ROAD sales between November 2001 and October 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 November 2012 sale was for 52% below the HPI. So the extrapolation line tracks at 52% below the HPI over time, until the October 2024 sale, where it rises to roughly the same level as the HPI. The line then continues to track in line with the HPI.
