171 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 171 PARK AVENUE sales from May 2014 and January 2022 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 2014 sale was for 13% above the HPI. So the extrapolation line tracks at 13% above the HPI over time, until the January 2022 sale, where it rises to 19% above the HPI. The line then continues to track at 19% above the HPI.

What might 171 PARK AVENUE be worth now?

This is based on house price inflation of 2.4%, between January 2022 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 2.4% inflationary increase is applied to the most recent sale price for 171 PARK AVENUE of £1,067,500 on 28th January 2022. For the value to have increased from £1,067,500 to £1,092,963 over the one year and one month to December 2024, the following assumptions must hold true:
