30 ST HELIER CLOSE 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 30 ST HELIER CLOSE sales between February 2006 and July 2025 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 December 2012 sale was for 39% below the HPI. So the extrapolation line tracks at 39% below the HPI over time, until the July 2025 sale, where it rises to 36% below the HPI. The line then continues to track at 36% below the HPI.
