4 BARNSWAY 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 4 BARNSWAY sales from March 2000 and February 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 2000 sale was for 13% above the HPI. So the extrapolation line tracks at 13% above the HPI over time, until the February 2021 sale, where it rises to 22% above the HPI. The line then continues to track at 22% above the HPI.

What might 4 BARNSWAY be worth now?

4 BARNSWAY might now be worth an estimated £1,119,708.

This is based on house price inflation of 12%, between February 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 12% inflationary increase is applied to the most recent sale price for 4 BARNSWAY of £1,000,000 on 25th February 2021. For the value to have increased from £1,000,000 to £1,119,708 over the four years to February 2025, the following assumptions must hold true:

• The value of 4 BARNSWAY has moved in line with the HPI for detached houses in the Dacorum local authority area.
• The February 2021 sale price of £1,000,000 represented a fair market value for the property.
• The size, condition, and specification of 4 BARNSWAY has not materially changed since February 2021.
