The below graph shows the average detached house price in the Cornwall local authority area over time, sourced from the HPI. The four 14 ARWENACK AVENUE sales between February 1997 and September 2017 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 June 2014 sale was for 33% above the HPI. So the extrapolation line tracks at 33% above the HPI over time, until the September 2017 sale, where it rises to 43% above the HPI. The line then continues to track at 43% above the HPI.

14 ARWENACK AVENUE might now be worth an estimated £626,352.
This is based on house price inflation of 34.1%, between September 2017 and August 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).
