17 CORNHILL Price Paid vs. HPI Average

The below graph shows the average detached house price in the City of Derby local authority area over time, sourced from the HPI. The five 17 CORNHILL sales between November 1998 and August 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 August 2019 sale was for 74% above the HPI. So the extrapolation line tracks at 74% above the HPI over time, until the August 2025 sale, where it falls to 35% above the HPI. The line then continues to track at 35% above the HPI.

What might 17 CORNHILL be worth now?
