70 ILLINGWORTH Price Paid vs. HPI Average

The below graph shows the average detached house price in the Windsor and Maidenhead local authority area over time, sourced from the HPI. The two 70 ILLINGWORTH sales from November 2002 and April 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 November 2002 sale was for 9% above the HPI. So the extrapolation line tracks at 9% above the HPI over time, until the April 2015 sale, where it falls to 5% below the HPI. The line then continues to track at 5% below the HPI.

What might 70 ILLINGWORTH be worth now?

This is based on house price inflation of 33.7%, between April 2015 and December 2024, for detached houses, in the Windsor and Maidenhead local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 33.7% inflationary increase is applied to the most recent sale price for 70 ILLINGWORTH of £789,950 on 22nd April 2015. For the value to have increased from £789,950 to £1,056,476 over the eight years and four months to December 2024, the following assumptions must hold true:
