TREVEAL Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cornwall local authority area over time, sourced from the HPI. The three TREVEAL sales between March 2016 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 March 2018 sale was for 161% above the HPI. So the extrapolation line tracks at 161% above the HPI over time, until the March 2025 sale, where it falls to 156% above the HPI. The line then continues to track at 156% above the HPI.

What might TREVEAL be worth now?

TREVEAL might now be worth an estimated £1,123,847.

This is based on house price inflation of 0.3%, between March 2025 and August 2025, for detached houses, in the Cornwall local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 0.3% inflationary increase is applied to the most recent sale price for TREVEAL of £1,120,000 on 19th March 2025. For the value to have increased from £1,120,000 to £1,123,847 over the seven months to August 2025, the following assumptions must hold true:

• The value of TREVEAL has moved in line with the HPI for detached houses in the Cornwall local authority area.
• The March 2025 sale price of £1,120,000 represented a fair market value for the property.
• The size, condition, and specification of TREVEAL has not materially changed since March 2025.
