7 THE DELL 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 7 THE DELL sales between November 2002 and September 2021 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 August 2011 sale was for 71% above the HPI. So the extrapolation line tracks at 71% above the HPI over time, until the September 2021 sale, where it falls to 53% above the HPI. The line then continues to track at 53% above the HPI.

What might 7 THE DELL be worth now?

7 THE DELL might now be worth an estimated £1,806,038.

This is based on house price inflation of 2.6%, between September 2021 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 2.6% inflationary increase is applied to the most recent sale price for 7 THE DELL of £1,760,000 on 30th September 2021. For the value to have increased from £1,760,000 to £1,806,038 over the two years and nine months to December 2024, the following assumptions must hold true:

• The value of 7 THE DELL has moved in line with the HPI for detached houses in the Harrow local authority area.
• The September 2021 sale price of £1,760,000 represented a fair market value for the property.
• The size, condition, and specification of 7 THE DELL has not materially changed since September 2021.
