11 OBSERVATORY ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Blackburn with Darwen local authority area over time, sourced from the HPI. The three 11 OBSERVATORY ROAD sales between October 1998 and April 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 November 2002 sale was for 33% below the HPI. So the extrapolation line tracks at 33% below the HPI over time, until the April 2022 sale, where it falls to 40% below the HPI. The line then continues to track at 40% below the HPI.
