55 LONGBOURN 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 three 55 LONGBOURN sales between June 2004 and June 2021 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 2010 sale was for 71% above the HPI. So the extrapolation line tracks at 71% above the HPI over time, until the June 2021 sale, where it falls to 49% above the HPI. The line then continues to track at 49% above the HPI.

What might 55 LONGBOURN be worth now?

55 LONGBOURN might now be worth an estimated £922,380.

This is based on house price inflation of 19%, between June 2021 and February 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 19% inflationary increase is applied to the most recent sale price for 55 LONGBOURN of £775,000 on 7th June 2021. For the value to have increased from £775,000 to £922,380 over the four years and four months to February 2025, the following assumptions must hold true:
