18 FORTH GWEDHEN Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Cornwall local authority area over time, sourced from the HPI. The six 18 FORTH GWEDHEN sales between July 2002 and October 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 September 2020 sale was for 9% above the HPI. So the extrapolation line tracks at 9% above the HPI over time, until the October 2022 sale, where it rises to 18% above the HPI. The line then continues to track at 18% above the HPI.

What might 18 FORTH GWEDHEN be worth now?

18 FORTH GWEDHEN might now be worth an estimated £323,551.

This is based on house price deflation of 8.5%, between October 2022 and June 2025, for semi-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 8.5% deflationary decrease is applied to the most recent sale price for 18 FORTH GWEDHEN of £353,500 on 3rd October 2022. For the value to have decreased from £353,500 to £323,551 over the three years and four months to June 2025, the following assumptions must hold true:

  • The value of 18 FORTH GWEDHEN has moved in line with the HPI for semi-detached houses in the Cornwall local authority area.
  • The October 2022 sale price of £353,500 represented a fair market value for the property.
  • The size, condition, and specification of 18 FORTH GWEDHEN has not materially changed since October 2022.
