43 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 43 LONGBOURN sales between June 2004 and July 2011 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 2010 sale was for 139% above the HPI. So the extrapolation line tracks at 139% above the HPI over time, until the July 2011 sale, where it rises to 151% above the HPI. The line then continues to track at 151% above the HPI.

What might 43 LONGBOURN be worth now?

43 LONGBOURN might now be worth an estimated £1,549,086.

This is based on house price inflation of 83.3%, between July 2011 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 83.3% inflationary increase is applied to the most recent sale price for 43 LONGBOURN of £845,000 on 29th July 2011. For the value to have increased from £845,000 to £1,549,086 over the fourteen years and five months to February 2025, the following assumptions must hold true:
