TREGARTHEN 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 two TREGARTHEN sales from February 2012 and June 2022 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 February 2012 sale was for 14% above the HPI. So the extrapolation line tracks at 14% above the HPI over time, until the June 2022 sale, where it rises to 34% above the HPI. The line then continues to track at 34% above the HPI.

What might TREGARTHEN be worth now?

TREGARTHEN might now be worth an estimated £584,848.

This is based on house price deflation of 0.9%, between June 2022 and February 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 0.9% deflationary decrease is applied to the most recent sale price for TREGARTHEN of £590,000 on 7th June 2022. For the value to have decreased from £590,000 to £584,848 over the three years and four months to February 2025, the following assumptions must hold true:

• The value of TREGARTHEN has moved in line with the HPI for detached houses in the Cornwall local authority area.
• The June 2022 sale price of £590,000 represented a fair market value for the property.
• The size, condition, and specification of TREGARTHEN has not materially changed since June 2022.
