27 HARLYN DRIVE 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 27 HARLYN DRIVE sales from July 1995 and January 2011 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 July 1995 sale was for 32% below the HPI. So the extrapolation line tracks at 32% below the HPI over time, until the January 2011 sale, where it rises to roughly the same level as the HPI. The line then continues to track in line with the HPI.

What might 27 HARLYN DRIVE be worth now?

27 HARLYN DRIVE might now be worth an estimated £915,511.

This is based on house price inflation of 83.1%, between January 2011 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 83.1% inflationary increase is applied to the most recent sale price for 27 HARLYN DRIVE of £500,000 on 12th January 2011. For the value to have increased from £500,000 to £915,511 over the twelve years and one month to December 2024, the following assumptions must hold true:

• The value of 27 HARLYN DRIVE has moved in line with the HPI for detached houses in the Hillingdon local authority area.
• The January 2011 sale price of £500,000 represented a fair market value for the property.
