The below graph shows the average semi-detached house price in the Amber Valley local authority area over time, sourced from the HPI. The two 11 BARTON KNOWLE sales from June 2000 and November 2002 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 June 2000 sale was for 38% above the HPI. So the extrapolation line tracks at 38% above the HPI over time, until the November 2002 sale, where it rises to 40% above the HPI. The line then continues to track at 40% above the HPI.

11 BARTON KNOWLE might now be worth an estimated £310,476.

The 202.9% inflationary increase is applied to the most recent sale price for 11 BARTON KNOWLE of £102,500 on 8th November 2002. For the value to have increased from £102,500 to £310,476 over the 24 years and seven months to April 2026, the following assumptions must hold true:
