21 OLDACRES Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Windsor and Maidenhead local authority area over time, sourced from the HPI. The two 21 OLDACRES sales from July 2011 and January 2025 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 July 2011 sale was for 4% below the HPI. So the extrapolation line tracks at 4% below the HPI over time, until the January 2025 sale, where it rises to 19% above the HPI. The line then continues to track at 19% above the HPI.

What might 21 OLDACRES be worth now?

This is based on house price inflation of 0.3%, between January 2025 and June 2025, for semi-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 0.3% inflationary increase is applied to the most recent sale price for 21 OLDACRES of £721,000 on 20th January 2025. For the value to have increased from £721,000 to £723,436 over the seven months to June 2025, the following assumptions must hold true:
