The below graph shows the average terraced house price in the Hillingdon local authority area over time, sourced from the HPI. The two 17 CORNWALL ROAD sales from April 1995 and March 2019 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 April 1995 sale was for 62% above the HPI. So the extrapolation line tracks at 62% above the HPI over time, until the March 2019 sale, where it rises to 65% above the HPI. The line then continues to track at 65% above the HPI.

17 CORNWALL ROAD might now be worth an estimated £754,467.
This is based on house price inflation of 17.4%, between March 2019 and April 2026, for terraced houses, in the Hillingdon local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 17.4% inflationary increase is applied to the most recent sale price for 17 CORNWALL ROAD of £642,500 on 12th March 2019. For the value to have increased from £642,500 to £754,467 over the six years and eleven months to April 2026, the following assumptions must hold true:
