The below graph shows the average detached house price in the Broadland local authority area over time, sourced from the HPI. The two 20 THORPE AVENUE sales from January 2002 and February 2008 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 January 2002 sale was for 45% below the HPI. So the extrapolation line tracks at 45% below the HPI over time, until the February 2008 sale, where it rises to 18% below the HPI. The line then continues to track at 18% below the HPI.

20 THORPE AVENUE might now be worth an estimated £342,202.
This is based on house price inflation of 59.2%, between February 2008 and October 2025, for detached houses, in the Broadland local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 59.2% inflationary increase is applied to the most recent sale price for 20 THORPE AVENUE of £215,000 on 12th February 2008. For the value to have increased from £215,000 to £342,202 over the sixteen years and four months to October 2025, the following assumptions must hold true:
