18 THE RETREAT 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 18 THE RETREAT sales between February 2002 and April 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 July 2016 sale was for 35% below the HPI. So the extrapolation line tracks at 35% below the HPI over time, until the April 2021 sale, where it falls to 42% below the HPI. The line then continues to track at 42% below the HPI.

What might 18 THE RETREAT be worth now?

18 THE RETREAT might now be worth an estimated £690,746.

This is based on house price inflation of 7.9%, between April 2021 and March 2025, 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 7.9% inflationary increase is applied to the most recent sale price for 18 THE RETREAT of £640,000 on 30th April 2021. For the value to have increased from £640,000 to £690,746 over the four years and one month to March 2025, the following assumptions must hold true:

• The value of 18 THE RETREAT has moved in line with the HPI for detached houses in the Harrow local authority area.
• The April 2021 sale price of £640,000 represented a fair market value for the property.
