11 WILLIAM STREET Price Paid vs. HPI Average

The below graph shows the average detached house price in the Oxford local authority area over time, sourced from the HPI. The five 11 WILLIAM STREET sales between January 1998 and March 2022 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 July 2016 sale was for 11% below the HPI. So the extrapolation line tracks at 11% below the HPI over time, until the March 2022 sale, where it falls to 13% below the HPI. The line then continues to track at 13% below the HPI.
