The below graph shows the average terraced house price in the Windsor and Maidenhead local authority area over time, sourced from the HPI. The two 100 PENN ROAD sales from April 1995 and February 2002 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 April 1995 sale was for 38% below the HPI. So the extrapolation line tracks at 38% below the HPI over time, until the February 2002 sale, which was also at 38% below the HPI.

100 PENN ROAD might now be worth an estimated £302,670.
This is based on house price inflation of 188.4%, between February 2002 and May 2026, for terraced 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 188.4% inflationary increase is applied to the most recent sale price for 100 PENN ROAD of £104,950 on 1st February 2002. For the value to have increased from £104,950 to £302,670 over the 23 years and nine months to May 2026, the following assumptions must hold true:
