21 ILEX CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the South Oxfordshire local authority area over time, sourced from the HPI. The two 21 ILEX CLOSE sales from November 2006 and May 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 November 2006 sale was for 7% below the HPI. So the extrapolation line tracks at 7% below the HPI over time, until the May 2025 sale, where it falls to 14% below the HPI. The line then continues to track at 14% below the HPI.
