15 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 two 15 THE MOUNT sales from March 2002 and June 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 March 2002 sale was for 19% above the HPI. So the extrapolation line tracks at 19% above the HPI over time, until the June 2021 sale, where it rises to 48% above the HPI. The line then continues to track at 48% above the HPI.

What might 15 THE MOUNT be worth now?

15 THE MOUNT might now be worth an estimated £1,679,890.

This is based on house price inflation of 5%, between June 2021 and March 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 5% inflationary increase is applied to the most recent sale price for 15 THE MOUNT of £1,600,000 on 28th June 2021. For the value to have increased from £1,600,000 to £1,679,890 over the four years and three months to March 2025, the following assumptions must hold true:

• The value of 15 THE MOUNT has moved in line with the HPI for detached houses in the Three Rivers local authority area.
• The June 2021 sale price of £1,600,000 represented a fair market value for the property.
• The size, condition, and specification of 15 THE MOUNT has not materially changed since June 2021.
