16 LONGBOURN 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 three 16 LONGBOURN sales between January 2005 and February 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 January 2008 sale was for 77% above the HPI. So the extrapolation line tracks at 77% above the HPI over time, until the February 2018 sale, where it falls to 41% above the HPI. The line then continues to track at 41% above the HPI.

What might 16 LONGBOURN be worth now?

16 LONGBOURN might now be worth an estimated £1,558,359.

This is based on house price inflation of 16.7%, between February 2018 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 16.7% inflationary increase is applied to the most recent sale price for 16 LONGBOURN of £1,335,000 on 27th February 2018. For the value to have increased from £1,335,000 to £1,558,359 over the five years and two months to December 2024, the following assumptions must hold true:
