25 COCKHILL Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Wiltshire local authority area over time, sourced from the HPI. The two 25 COCKHILL sales from August 1997 and July 1999 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 1997 sale was for 20% below the HPI. So the extrapolation line tracks at 20% below the HPI over time, until the July 1999 sale, where it rises to 26% above the HPI. The line then continues to track at 26% above the HPI.

What might 25 COCKHILL be worth now?

25 COCKHILL might now be worth an estimated £414,515.

This is based on house price inflation of 285.6%, between July 1999 and December 2024, for semi-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 285.6% inflationary increase is applied to the most recent sale price for 25 COCKHILL of £107,500 on 19th July 1999. For the value to have increased from £107,500 to £414,515 over the 24 years and seven months to December 2024, the following assumptions must hold true:

• The value of 25 COCKHILL has moved in line with the HPI for semi-detached houses in the Wiltshire local authority area.
• The July 1999 sale price of £107,500 represented a fair market value for the property.
