The below graph shows the average detached house price in the Cornwall local authority area over time, sourced from the HPI. The four 21 TRELAWNE ROAD sales between February 2000 and November 2013 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 January 2013 sale was for 18% below the HPI. So the extrapolation line tracks at 18% below the HPI over time, until the November 2013 sale, where it rises to 16% below the HPI. The line then continues to track at 16% below the HPI.
21 TRELAWNE ROAD might now be worth an estimated £367,821.
This is based on house price inflation of 54.9%, between November 2013 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).
