The below graph shows the average detached house price in the Cornwall local authority area over time, sourced from the HPI. The two 25 TRELYN sales from July 2003 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 July 2003 sale was for 6% above the HPI. So the extrapolation line tracks at 6% above the HPI over time, until the November 2013 sale, where it rises to 57% above the HPI. The line then continues to track at 57% above the HPI.
25 TRELYN might now be worth an estimated £685,308.
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).
The 54.9% inflationary increase is applied to the most recent sale price for 25 TRELYN of £442,500 on 12th November 2013. For the value to have increased from £442,500 to £685,308 over the twelve years and nine months to February 2025, the following assumptions must hold true:
