143 PARK AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Hillingdon local authority area over time, sourced from the HPI. The two 143 PARK AVENUE sales from October 2008 and November 2018 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 2008 sale was for 2% below the HPI. So the extrapolation line tracks at 2% below the HPI over time, until the November 2018 sale, where it rises to 52% above the HPI. The line then continues to track at 52% above the HPI.

What might 143 PARK AVENUE be worth now?

143 PARK AVENUE might now be worth an estimated £1,399,799.

This is based on house price inflation of 12%, between November 2018 and December 2024, for 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 12% inflationary increase is applied to the most recent sale price for 143 PARK AVENUE of £1,250,000 on 23rd November 2018. For the value to have increased from £1,250,000 to £1,399,799 over the five years and eleven months to December 2024, the following assumptions must hold true:

• The value of 143 PARK AVENUE has moved in line with the HPI for detached houses in the Hillingdon local authority area.
• The November 2018 sale price of £1,250,000 represented a fair market value for the property.
• The size, condition, and specification of 143 PARK AVENUE has not materially changed since November 2018.
