The below graph shows the average semi-detached house price in the Basildon local authority area over time, sourced from the HPI. The three 21 THE FIRLE sales between June 2001 and February 2016 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 May 2012 sale was for 39% above the HPI. So the extrapolation line tracks at 39% above the HPI over time, until the February 2016 sale, where it falls to 27% above the HPI. The line then continues to track at 27% above the HPI.
21 THE FIRLE might now be worth an estimated £528,694.
This is based on house price inflation of 41%, between February 2016 and February 2025, for semi-detached houses, in the Basildon local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 41% inflationary increase is applied to the most recent sale price for 21 THE FIRLE of £375,000 on 5th February 2016. For the value to have increased from £375,000 to £528,694 over the nine years to February 2025, the following assumptions must hold true:
