18 TREWITHAN PARC 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 three 18 TREWITHAN PARC sales between June 2004 and January 2021 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 August 2006 sale was for 16% above the HPI. So the extrapolation line tracks at 16% above the HPI over time, until the January 2021 sale, where it rises to 17% above the HPI. The line then continues to track at 17% above the HPI.

What might 18 TREWITHAN PARC be worth now?

This is based on house price inflation of 16.7%, between January 2021 and February 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 16.7% inflationary increase is applied to the most recent sale price for 18 TREWITHAN PARC of £290,000 on 28th January 2021. For the value to have increased from £290,000 to £338,512 over the three years and eleven months to February 2025, the following assumptions must hold true:
