18 COCK GREEN Price Paid vs. HPI Average

The below graph shows the average detached house price in the Harlow local authority area over time, sourced from the HPI. The five 18 COCK GREEN sales between July 1998 and November 2018 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 March 2013 sale was for 10% above the HPI. So the extrapolation line tracks at 10% above the HPI over time, until the November 2018 sale, where it falls to 4% above the HPI. The line then continues to track at 4% above the HPI.

What might 18 COCK GREEN be worth now?

18 COCK GREEN might now be worth an estimated £644,155.

This is based on house price inflation of 12%, between November 2018 and December 2024, for detached houses, in the Harlow local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 12% inflationary increase is applied to the most recent sale price for 18 COCK GREEN of £575,000 on 13th November 2018. For the value to have increased from £575,000 to £644,155 over the five years and eleven months to December 2024, the following assumptions must hold true:

• The value of 18 COCK GREEN has moved in line with the HPI for detached houses in the Harlow local authority area.
• The November 2018 sale price of £575,000 represented a fair market value for the property.
• The size, condition, and specification of 18 COCK GREEN has not materially changed since November 2018.
