18 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 four 18 ISAAC SQUARE sales between June 2002 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 2010 sale was for 34% above the HPI. So the extrapolation line tracks at 34% above the HPI over time, until the November 2023 sale, where it falls to 19% above the HPI. The line then continues to track at 19% above the HPI.

What might 18 ISAAC SQUARE be worth now?

The 1.6% inflationary increase is applied to the most recent sale price for 18 ISAAC SQUARE of £485,000 on 6th November 2023. For the value to have increased from £485,000 to £492,973 over the eleven months to December 2024, the following assumptions must hold true:
