The below graph shows the average terraced house price in the Cornwall local authority area over time, sourced from the HPI. The four 15 TREGELLAS ROAD sales between September 1997 and August 2024 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 March 2021 sale was for 11% above the HPI. So the extrapolation line tracks at 11% above the HPI over time, until the August 2024 sale, where it rises to 19% above the HPI. The line then continues to track at 19% above the HPI.

15 TREGELLAS ROAD might now be worth an estimated £282,742.
This is based on house price inflation of 2.8%, between August 2024 and August 2025, for terraced 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 2.8% inflationary increase is applied to the most recent sale price for 15 TREGELLAS ROAD of £275,000 on 21st August 2024. For the value to have increased from £275,000 to £282,742 over the one year to August 2025, the following assumptions must hold true:
