25 HARRIETS HEIGHTS Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Blackburn with Darwen local authority area over time, sourced from the HPI. The two 25 HARRIETS HEIGHTS sales from April 2019 and April 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 April 2019 sale was for 50% above the HPI. So the extrapolation line tracks at 50% above the HPI over time, until the April 2024 sale, where it falls to 45% above the HPI. The line then continues to track at 45% above the HPI.
