The below graph shows the average semi-detached house price in the West Berkshire local authority area over time, sourced from the HPI. The two 5 WILLIAMSON CLOSE sales from August 2011 and December 2015 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 August 2011 sale was for 45% above the HPI. So the extrapolation line tracks at 45% above the HPI over time, until the December 2015 sale, where it falls to 23% above the HPI. The line then continues to track at 23% above the HPI.

5 WILLIAMSON CLOSE might now be worth an estimated £509,289.
This is based on house price inflation of 32.3%, between December 2015 and April 2026, for semi-detached houses, in the West Berkshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 32.3% inflationary increase is applied to the most recent sale price for 5 WILLIAMSON CLOSE of £384,950 on 9th December 2015. For the value to have increased from £384,950 to £509,289 over the eleven years and eight months to April 2026, the following assumptions must hold true:
