40 SEVEN ASH GREEN Price Paid vs. HPI Average

The below graph shows the average detached house price in the Chelmsford local authority area over time, sourced from the HPI. The three 40 SEVEN ASH GREEN sales between July 1996 and November 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 August 2003 sale was for 56% above the HPI. So the extrapolation line tracks at 56% above the HPI over time, until the November 2023 sale, where it falls to 50% above the HPI. The line then continues to track at 50% above the HPI.

What might 40 SEVEN ASH GREEN be worth now?

This is based on house price inflation of 3.7%, between November 2023 and August 2025, for detached houses, in the Chelmsford local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 3.7% inflationary increase is applied to the most recent sale price for 40 SEVEN ASH GREEN of £1,000,000 on 24th November 2023. For the value to have increased from £1,000,000 to £1,036,531 over the two years and three months to August 2025, the following assumptions must hold true:
