21 BOWDEN ROAD 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 21 BOWDEN ROAD sales between July 2000 and September 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 May 2007 sale was for 11% above the HPI. So the extrapolation line tracks at 11% above the HPI over time, until the September 2015 sale, where it falls to 3% below the HPI. The line then continues to track at 3% below the HPI.

What might 21 BOWDEN ROAD be worth now?

21 BOWDEN ROAD might now be worth an estimated £1,112,215.

This is based on house price inflation of 34%, between September 2015 and February 2025, 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 34% inflationary increase is applied to the most recent sale price for 21 BOWDEN ROAD of £830,000 on 4th September 2015. For the value to have increased from £830,000 to £1,112,215 over the ten years and seven months to February 2025, the following assumptions must hold true:

  • The value of 21 BOWDEN ROAD has moved in line with the HPI for detached houses in the Windsor and Maidenhead local authority area.
  • The September 2015 sale price of £830,000 represented a fair market value for the property.
  • The size, condition, and specification of 21 BOWDEN ROAD has not materially changed since September 2015.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
