The below graph shows the average detached house price in the Cornwall local authority area over time, sourced from the HPI. The five 21 ROBARTES TERRACE sales between June 1997 and October 2020 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 2011 sale was for 5% above the HPI. So the extrapolation line tracks at 5% above the HPI over time, until the October 2020 sale, where it falls to 3% above the HPI. The line then continues to track at 3% above the HPI.

21 ROBARTES TERRACE might now be worth an estimated £439,779.
This is based on house price inflation of 15.7%, between October 2020 and May 2026, 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).
The 15.7% inflationary increase is applied to the most recent sale price for 21 ROBARTES TERRACE of £380,000 on 19th October 2020. For the value to have increased from £380,000 to £439,779 over the six years and five months to May 2026, the following assumptions must hold true:
