1 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 1 CASTLE AVENUE sales from August 2001 and March 2006 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 August 2001 sale was for 26% below the HPI. So the extrapolation line tracks at 26% below the HPI over time, until the March 2006 sale, where it rises to 19% below the HPI. The line then continues to track at 19% below the HPI.

What might 1 CASTLE AVENUE be worth now?

1 CASTLE AVENUE might now be worth an estimated £460,648.

This is based on house price inflation of 119.4%, between March 2006 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 119.4% inflationary increase is applied to the most recent sale price for 1 CASTLE AVENUE of £210,000 on 31st March 2006. For the value to have increased from £210,000 to £460,648 over the seventeen years and three months to December 2024, the following assumptions must hold true:

• The value of 1 CASTLE AVENUE has moved in line with the HPI for semi-detached houses in the Hillingdon local authority area.
• The March 2006 sale price of £210,000 represented a fair market value for the property.
• The size, condition, and specification of 1 CASTLE AVENUE has not materially changed since March 2006.
