The below graph shows the average detached house price in the Wiltshire local authority area over time, sourced from the HPI. The two 1 THE THORNS sales from August 2002 and March 2014 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 2002 sale was for 9% below the HPI. So the extrapolation line tracks at 9% below the HPI over time, until the March 2014 sale, where it falls to 17% below the HPI. The line then continues to track at 17% below the HPI.
1 THE THORNS might now be worth an estimated £432,822.
This is based on house price inflation of 57.4%, between March 2014 and December 2024, for detached houses, in the Wiltshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 57.4% inflationary increase is applied to the most recent sale price for 1 THE THORNS of £275,000 on 26th March 2014. For the value to have increased from £275,000 to £432,822 over the nine years and three months to December 2024, the following assumptions must hold true:
