TRELAWN 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 two TRELAWN sales from March 2016 and October 2024 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 March 2016 sale was for 44% below the HPI. So the extrapolation line tracks at 44% below the HPI over time, until the October 2024 sale, where it rises to 23% below the HPI. The line then continues to track at 23% below the HPI.

What might TRELAWN be worth now?

TRELAWN might now be worth an estimated £402,544.

This is based on house price deflation of 0.6%, between October 2024 and February 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 0.6% deflationary decrease is applied to the most recent sale price for TRELAWN of £405,000 on 23rd October 2024. For the value to have decreased from £405,000 to £402,544 over the one year and eight months to February 2025, the following assumptions must hold true:

• The value of TRELAWN has moved in line with the HPI for detached houses in the Wiltshire local authority area.
• The October 2024 sale price of £405,000 represented a fair market value for the property.
• The size, condition, and specification of TRELAWN has not materially changed since October 2024.
