The below graph shows the average semi-detached house price in the Cornwall local authority area over time, sourced from the HPI. The three 19 PORTHIA ROAD sales between May 1997 and April 2015 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 November 2010 sale was for 4% below the HPI. So the extrapolation line tracks at 4% below the HPI over time, until the April 2015 sale, where it rises to 4% above the HPI. The line then continues to track at 4% above the HPI.
19 PORTHIA ROAD might now be worth an estimated £298,545.
This is based on house price inflation of 49.3%, between April 2015 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 49.3% inflationary increase is applied to the most recent sale price for 19 PORTHIA ROAD of £199,950 on 17th April 2015. For the value to have increased from £199,950 to £298,545 over the ten years and two months to February 2025, the following assumptions must hold true:
