11 HELENA ROAD Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Windsor and Maidenhead local authority area over time, sourced from the HPI. The five 11 HELENA ROAD sales between November 2003 and January 2025 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 2008 sale was for 69% above the HPI. So the extrapolation line tracks at 69% above the HPI over time, until the January 2025 sale, where it falls to 25% above the HPI. The line then continues to track at 25% above the HPI.

What might 11 HELENA ROAD be worth now?
