17 SYDENHAM CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cherwell local authority area over time, sourced from the HPI. The two 17 SYDENHAM CLOSE sales from May 2006 and September 2019 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 2006 sale was for 2% above the HPI. So the extrapolation line tracks at 2% above the HPI over time, until the September 2019 sale, where it falls to 23% below the HPI. The line then continues to track at 23% below the HPI.
