20 THE SPINNEY Price Paid vs. HPI Average

The below graph shows the average detached house price in the Harrow local authority area over time, sourced from the HPI. The three 20 THE SPINNEY sales between March 2000 and July 2008 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 June 2002 sale was for 36% above the HPI. So the extrapolation line tracks at 36% above the HPI over time, until the July 2008 sale, where it falls to 6% above the HPI. The line then continues to track at 6% above the HPI.

What might 20 THE SPINNEY be worth now?

20 THE SPINNEY might now be worth an estimated £1,249,715.

This is based on house price inflation of 78.5%, between July 2008 and December 2024, for detached houses, in the Harrow local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 78.5% inflationary increase is applied to the most recent sale price for 20 THE SPINNEY of £700,000 on 24th July 2008. For the value to have increased from £700,000 to £1,249,715 over the fifteen years and seven months to December 2024, the following assumptions must hold true:

• The value of 20 THE SPINNEY has moved in line with the HPI for detached houses in the Harrow local authority area.
• The July 2008 sale price of £700,000 represented a fair market value for the property.
