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 three 8 RAVENSWING AVENUE sales between August 1996 and September 2017 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 August 2003 sale was for 256% above the HPI. So the extrapolation line tracks at 256% above the HPI over time, until the September 2017 sale, where it falls to 122% above the HPI. The line then continues to track at 122% above the HPI.

8 RAVENSWING AVENUE might now be worth an estimated £387,379.

The 48.4% inflationary increase is applied to the most recent sale price for 8 RAVENSWING AVENUE of £261,000 on 29th September 2017. For the value to have increased from £261,000 to £387,379 over the eight years and one month to August 2025, the following assumptions must hold true:
