20 ISAAC SQUARE 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 20 ISAAC SQUARE sales between April 2002 and July 2019 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 October 2006 sale was for 21% below the HPI. So the extrapolation line tracks at 21% below the HPI over time, until the July 2019 sale, where it falls to 33% below the HPI. The line then continues to track at 33% below the HPI.

What might 20 ISAAC SQUARE be worth now?

20 ISAAC SQUARE might now be worth an estimated £450,009.

This is based on house price inflation of 12.5%, between July 2019 and December 2024, 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 12.5% inflationary increase is applied to the most recent sale price for 20 ISAAC SQUARE of £400,000 on 11th July 2019. For the value to have increased from £400,000 to £450,009 over the four years and seven months to December 2024, the following assumptions must hold true:

• The value of 20 ISAAC SQUARE has moved in line with the HPI for detached houses in the Chelmsford local authority area.
• The July 2019 sale price of £400,000 represented a fair market value for the property.
