4 THE FOLLY Price Paid vs. HPI Average

The below graph shows the average detached house price in the Wiltshire local authority area over time, sourced from the HPI. The four 4 THE FOLLY sales between December 1995 and March 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 December 2024 sale was for 61% below the HPI. So the extrapolation line tracks at 61% below the HPI over time, until the March 2025 sale, where it rises to 32% above the HPI. The line then continues to track at 32% above the HPI.

What might 4 THE FOLLY be worth now?

4 THE FOLLY might now be worth an estimated £676,795.

This is based on house price deflation of 0.5%, between March 2025 and June 2025, 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 0.5% deflationary decrease is applied to the most recent sale price for 4 THE FOLLY of £680,000 on 25th March 2025. For the value to have decreased from £680,000 to £676,795 over the nine months to June 2025, the following assumptions must hold true:

• The value of 4 THE FOLLY has moved in line with the HPI for detached houses in the Wiltshire local authority area.
• The March 2025 sale price of £680,000 represented a fair market value for the property.
• The size, condition, and specification of 4 THE FOLLY has not materially changed since March 2025.
