The below graph shows the average semi-detached house price in the Cornwall local authority area over time, sourced from the HPI. The three 4 GWEAL WARTHA sales between March 1998 and September 2014 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 October 2002 sale was for 4% above the HPI. So the extrapolation line tracks at 4% above the HPI over time, until the September 2014 sale, where it falls to 14% below the HPI. The line then continues to track at 14% below the HPI.
4 GWEAL WARTHA might now be worth an estimated £248,605.
This is based on house price inflation of 50.3%, between September 2014 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 50.3% inflationary increase is applied to the most recent sale price for 4 GWEAL WARTHA of £165,400 on 5th September 2014. For the value to have increased from £165,400 to £248,605 over the eleven years and seven months to February 2025, the following assumptions must hold true:
