| Date | Price | HPI Price | Variation from HPI |

The below graph shows the average semi-detached house price in the Hillingdon local authority area over time, sourced from the HPI. The two 21 COLLEGE DRIVE sales from November 2002 and April 2023 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 2002 sale was for 29% above the HPI. So the extrapolation line tracks at 29% above the HPI over time, until the April 2023 sale, where it rises to 57% above the HPI. The line then continues to track at 57% above the HPI.

21 COLLEGE DRIVE might now be worth an estimated £911,977.
This is based on house price inflation of 4.5%, between April 2023 and May 2026, for semi-detached 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 4.5% inflationary increase is applied to the most recent sale price for 21 COLLEGE DRIVE of £872,667 on 12th April 2023. For the value to have increased from £872,667 to £911,977 over the two years and eleven months to May 2026, the following assumptions must hold true:
