| Date | Price | HPI Price | Variation from HPI |

The below graph shows the average semi-detached house price in the Harlow local authority area over time, sourced from the HPI. The three 20 NORTHBROOKS sales between February 2003 and September 2006 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 April 2006 sale was for 57% below the HPI. So the extrapolation line tracks at 57% below the HPI over time, until the September 2006 sale, where it rises to 52% below the HPI. The line then continues to track at 52% below the HPI.

20 NORTHBROOKS might now be worth an estimated £204,318.
This is based on house price inflation of 94.6%, between September 2006 and May 2026, for semi-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 94.6% inflationary increase is applied to the most recent sale price for 20 NORTHBROOKS of £105,000 on 29th September 2006. For the value to have increased from £105,000 to £204,318 over the twenty years and four months to May 2026, the following assumptions must hold true:
