The below graph shows the average semi-detached house price in the Castle Point local authority area over time, sourced from the HPI. The three 17 SIDWELL AVENUE sales between December 2004 and February 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 October 2006 sale was for 19% above the HPI. So the extrapolation line tracks at 19% above the HPI over time, until the February 2018 sale, where it falls to 15% above the HPI. The line then continues to track at 15% above the HPI.
17 SIDWELL AVENUE might now be worth an estimated £387,451.
This is based on house price inflation of 21.1%, between February 2018 and March 2025, for semi-detached houses, in the Castle Point local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 21.1% inflationary increase is applied to the most recent sale price for 17 SIDWELL AVENUE of £320,000 on 12th February 2018. For the value to have increased from £320,000 to £387,451 over the six years and eleven months to March 2025, the following assumptions must hold true:
