23 CASTLE AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Hillingdon local authority area over time, sourced from the HPI. The two 23 CASTLE AVENUE sales from May 2002 and November 2004 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 May 2002 sale was for 35% below the HPI. So the extrapolation line tracks at 35% below the HPI over time, until the November 2004 sale, where it rises to 25% below the HPI. The line then continues to track at 25% below the HPI.

What might 23 CASTLE AVENUE be worth now?

23 CASTLE AVENUE might now be worth an estimated £424,554.

This is based on house price inflation of 123.4%, between November 2004 and December 2024, 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 123.4% inflationary increase is applied to the most recent sale price for 23 CASTLE AVENUE of £190,000 on 5th November 2004. For the value to have increased from £190,000 to £424,554 over the nineteen years and eleven months to December 2024, the following assumptions must hold true:
