12 ISAAC SQUARE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Chelmsford local authority area over time, sourced from the HPI. The three 12 ISAAC SQUARE sales between June 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 February 2006 sale was for 41% above the HPI. So the extrapolation line tracks at 41% above the HPI over time, until the June 2021 sale, where it falls to 35% above the HPI. The line then continues to track at 35% above the HPI.

What might 12 ISAAC SQUARE be worth now?

This is based on house price inflation of 13.1%, between June 2021 and December 2024, for semi-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 13.1% inflationary increase is applied to the most recent sale price for 12 ISAAC SQUARE of £495,000 on 3rd June 2021. For the value to have increased from £495,000 to £559,917 over the two years and six months to December 2024, the following assumptions must hold true:
