33 BLENHEIM ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Slough local authority area over time, sourced from the HPI. The two 33 BLENHEIM ROAD sales from February 1998 and June 2020 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 February 1998 sale was for 10% above the HPI. So the extrapolation line tracks at 10% above the HPI over time, until the June 2020 sale, where it rises to 32% above the HPI. The line then continues to track at 32% above the HPI.
