15 THIRLMERE DRIVE 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 three 15 THIRLMERE DRIVE sales between May 2005 and February 2026 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 September 2008 sale was for 14% above the HPI. So the extrapolation line tracks at 14% above the HPI over time, until the February 2026 sale, where it rises to 19% above the HPI. The line then continues to track at 19% above the HPI.

What might 15 THIRLMERE DRIVE be worth now?
