22 FLAG WALK Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Hillingdon local authority area over time, sourced from the HPI. The two 22 FLAG WALK sales from March 1995 and July 1999 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 March 1995 sale was for 35% above the HPI. So the extrapolation line tracks at 35% above the HPI over time, until the July 1999 sale, where it rises to 60% above the HPI. The line then continues to track at 60% above the HPI.

What might 22 FLAG WALK be worth now?

22 FLAG WALK might now be worth an estimated £731,069.

This is based on house price inflation of 357.1%, between July 1999 and April 2026, for terraced 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 357.1% inflationary increase is applied to the most recent sale price for 22 FLAG WALK of £159,950 on 16th July 1999. For the value to have increased from £159,950 to £731,069 over the 27 years and three months to April 2026, the following assumptions must hold true:

• The value of 22 FLAG WALK has moved in line with the HPI for terraced houses in the Hillingdon local authority area.
• The July 1999 sale price of £159,950 represented a fair market value for the property.
