The below graph shows the average detached house price in the Vale of White Horse local authority area over time, sourced from the HPI. The two 7 CHILBROOK sales from August 1996 and January 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 August 1996 sale was for 78% above the HPI. So the extrapolation line tracks at 78% above the HPI over time, until the January 2018 sale, where it falls to 24% above the HPI. The line then continues to track at 24% above the HPI.

7 CHILBROOK might now be worth an estimated £817,687.
This is based on house price inflation of 23.9%, between January 2018 and May 2026, for detached houses, in the Vale of White Horse local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 23.9% inflationary increase is applied to the most recent sale price for 7 CHILBROOK of £660,000 on 12th January 2018. For the value to have increased from £660,000 to £817,687 over the seven years and eight months to May 2026, the following assumptions must hold true:
