128 MERCIAN WAY Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Slough local authority area over time, sourced from the HPI. The three 128 MERCIAN WAY sales between July 1996 and June 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 March 2021 sale was for 5% above the HPI. So the extrapolation line tracks at 5% above the HPI over time, until the June 2025 sale, where it falls to roughly the same level as the HPI. The line then continues to track in line with the HPI.
