Land registry data shows three sales for 23 DEANE AVENUE since 1st January 1995. The below table shows the price paid for the three sales, along with the average semi-detached price in the Hillingdon local authority area for the corresponding sale date.

The average price is sourced from the Office for National Statistics' House Price Index (HPI).
| Date | Price | HPI Price | Variation from HPI |
|---|---|---|---|
2012 31 MAY | £300,000 | £300,442 | Close to HPI |
2004 5 OCT | £258,950 | £252,734 | 2% above HPI |

The below graph shows the average semi-detached house price in the Hillingdon local authority area over time, sourced from the HPI. The three 23 DEANE AVENUE sales between July 2000 and May 2012 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 October 2004 sale was for 2% above the HPI. So the extrapolation line tracks at 2% above the HPI over time, until the May 2012 sale, where it falls to roughly the same level as the HPI. The line then continues to track in line with the HPI.

23 DEANE AVENUE might now be worth an estimated £580,767.
This is based on house price inflation of 93.6%, between May 2012 and April 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 93.6% inflationary increase is applied to the most recent sale price for 23 DEANE AVENUE of £300,000 on 31st May 2012. For the value to have increased from £300,000 to £580,767 over the fourteen years and one month to April 2026, the following assumptions must hold true:
