20 SEVENACRES Price Paid vs. HPI Average

The below graph shows the average detached house price in the East Hertfordshire local authority area over time, sourced from the HPI. The two 20 SEVENACRES sales from September 2015 and March 2023 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 September 2015 sale was for 7% above the HPI. So the extrapolation line tracks at 7% above the HPI over time, until the March 2023 sale, where it rises to 13% above the HPI. The line then continues to track at 13% above the HPI.

What might 20 SEVENACRES be worth now?

This is based on house price deflation of 1.3%, between March 2023 and February 2025, for detached houses, in the East Hertfordshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 1.3% deflationary decrease is applied to the most recent sale price for 20 SEVENACRES of £975,000 on 10th March 2023. For the value to have decreased from £975,000 to £962,758 over the two years and one month to February 2025, the following assumptions must hold true:

• The March 2023 sale price of £975,000 represented a fair market value for the property.
