TREWIN 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 TREWIN sales between December 2002 and September 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 2005 sale was for 15% above the HPI. So the extrapolation line tracks at 15% above the HPI over time, until the September 2025 sale, where it falls to 4% below the HPI. The line then continues to track at 4% below the HPI.

What might TREWIN be worth now?

TREWIN might now be worth an estimated £405,409.

This is based on house price deflation of 1.6%, between September 2025 and April 2026, 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 1.6% deflationary decrease is applied to the most recent sale price for TREWIN of £412,000 on 10th September 2025. For the value to have decreased from £412,000 to £405,409 over the one year and five months to April 2026, the following assumptions must hold true:

• The value of TREWIN has moved in line with the HPI for detached houses in the Cornwall local authority area.
• The September 2025 sale price of £412,000 represented a fair market value for the property.
• The size, condition, and specification of TREWIN has not materially changed since September 2025.
