1 MILLFIELD COTTAGE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Dacorum local authority area over time, sourced from the HPI. The two 1 MILLFIELD COTTAGE sales from January 2018 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 January 2018 sale was for 2% below the HPI. So the extrapolation line tracks at 2% below the HPI over time, until the September 2021 sale, where it rises to 60% above the HPI. The line then continues to track at 60% above the HPI.

What might 1 MILLFIELD COTTAGE be worth now?

1 MILLFIELD COTTAGE might now be worth an estimated £1,471,778.

This is based on house price inflation of 9%, between September 2021 and February 2025, for detached houses, in the Dacorum local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 9% inflationary increase is applied to the most recent sale price for 1 MILLFIELD COTTAGE of £1,350,000 on 3rd September 2021. For the value to have increased from £1,350,000 to £1,471,778 over the four years and seven months to February 2025, the following assumptions must hold true:

• The value of 1 MILLFIELD COTTAGE has moved in line with the HPI for detached houses in the Dacorum local authority area.
• The September 2021 sale price of £1,350,000 represented a fair market value for the property.
