21 THE MOUNT Price Paid vs. HPI Average

The below graph shows the average detached house price in the Three Rivers local authority area over time, sourced from the HPI. The four 21 THE MOUNT sales between April 1996 and October 2024 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 2015 sale was for 41% above the HPI. So the extrapolation line tracks at 41% above the HPI over time, until the October 2024 sale, which was also at 41% above the HPI.

What might 21 THE MOUNT be worth now?

This is based on house price deflation of 6.5%, between October 2024 and February 2025, for detached houses, in the Three Rivers local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 6.5% deflationary decrease is applied to the most recent sale price for 21 THE MOUNT of £1,700,000 on 31st October 2024. For the value to have decreased from £1,700,000 to £1,590,052 over the one year and eight months to February 2025, the following assumptions must hold true:

• The value of 21 THE MOUNT has moved in line with the HPI for detached houses in the Three Rivers local authority area.
• The October 2024 sale price of £1,700,000 represented a fair market value for the property.
